GS82-AA02 E-Bike Speed Sensor

With the increasing popularity and growing trend of e-bikes, bicycle system suppliers have set goals to optimize power and performance of their drive systems. In order to support the driver in the best possible way, sensors are needed to deliver the required data and therefore adapt the engine's power support. An essential component is the ZF e-bike sensor for measuring the current speed, which is based on Hall technology with significant advantages over conventional reed switches.

Especially for high-quality e-bikes, all components need to be functional, from the drive to the battery and cabling. This is also the case with the ZF e-bike sensor. Speed sensors of the GS series have been specially developed for use in Pedelecs and S-Pedelecs. The extremely compact design meets the necessary requirements for the use in e-bikes.

The sensors are based on the principle of Hall-effect and therefore they are non-contact and durable. In combination with ferromagnetic target wheels, a high-resolution speed measurement with over 50 pulses per revolution can be implemented without any problems. In practice, this leads to a finer and quicker response from the e-bike drive - especially at lower speeds (e.g. when starting up a hill). The differential measurement of the magnetic flux also increases the robustness of the sensor against vibrations. In addition, there is no need for an external magnet, which is used with conventional reed switches. These are frail against even slight shifts on the spoke, which leads to functional failures and shut down of the drive unit.

The GS82-AA02 sensor is compact at 21.75mm length, 9.35mm diameter. As an interface to the drive system, the Higo connector has a cross-section of only 0.14mm² and due to its small size is prevalent in the e-bike industry. Depending on the customer's requirements the contact via connector, as well as the cable length, can be preselected individually. The sensor requires a constant voltage supply of 6.5 - 20 VDC and measures frequencies between 1 and 2,500 Hz. They are designed for a temperature range from -25 ° C to + 85°C to fulfill the declaration of conformity in the e-bike industry.  This sensor was originally developed for ABS applications. In addition to e-bikes, other target markets include e-scooters and various sports equipment for this small and efficient sensor.

ZF E-bike Speed Sensor Enriches the New Trend of ABS Applications

The ABS system has become indispensable in passenger and commercial vehicles. This safety function is also becoming increasingly popular for e-bikes. Bicycle accidents are often caused by uncontrolled braking, especially during emergency stops or braking on gravel and wet roads. The anti-lock braking system ensures a safe slowdown by evenly deaccelerating the front and rear wheels. To do this, the speed on both wheels must be measured constantly and precisely. The Hall-based speed sensor from ZF promotes this solution.

The ZF e-bike speed sensor GS82-AA02 was specially developed for use in Pedelecs and S-Pedelecs. Based on Hall technology, the sensor in combination with an external, ferromagnetic speed disk achieves a high-resolution speed measurement. The sensor targets the slot structure of the speed disc and, depending on the number of slots, it transmits up to 50 or more speed signals per wheel revolution. In practice, this leads to a finer and quicker response from the e-bike drive. The ABS system also benefits from the high resolution in speed. With the precise speed values of both wheels, the ABS control unit can adjust the wheels to each other and brake them in a controlled manner.

The extremely compact design (21.75mm long x 9.35mm in diameter) of the sensor fulfills the necessary requirements for the use in e-bikes. The speed sensor is based on the principle of the Hall effect and therefore it is contactless and wear-free. The differential measurement of the magnetic flux also increases the robustness of the sensor against vibrations. Depending on the customer's requirements the contact via connector, as well as the cable length, can be preselected individually. The sensor requires a constant voltage supply of 6.5 - 20 VDC and measures frequencies between 1 and 2,500 Hz. They are designed for a temperature range from -25 °C to + 85 °C to fulfill the declaration of conformity in the e-bike industry.

Characteristics
• Hall based non-contact and solid-state sensor
• Virtually unlimited life, no wear and tear from friction
• Immune to vibration, shock, dirt or water for an improved functional safety especially for Pedelecs, S-Pedelecs and E-Scooter
• Available standard product with Higo connector. Flexibility in terms of cable length and connector assemblies.
• High resolution in combination with speed and brake disk especially for slow speeds (e.g. hill starts)
• Hall sensor with speed disk for improved manipulation resistance and robustness
• Best suitable also for ABS-Systems

Marine engine controls benefit from ZF Hall-based position sensors

Hall-based position sensors are becoming widely used in a wide variety of applications due to their contactless and wear-free measurement method. These sensors are used in outboard marine engines to control the trim level. Marine drive manufacturers rely on the Hall-based position sensors from ZF as reliable and robust components for their overall drive system.

The Hall-based position sensors from ZF have been established as a reliable sensor solution for marine applications, especially for the inclination and trim measurement of outboard motors. To ensure optimal performance of a boat depending on the speed, the outboard motor must have a certain inclination. Both angle and linear position sensors are used with an associated external magnet carrier to monitor and realign the current inclination of the motor. The sensors are completely contactless and have an almost unlimited lifetime, as no wear and tear occur caused by abrasion. For position measurement, the external magnet is attached a few millimeters above the sensor. If the magnet rotates, the magnetic field changes, which again leads to a change in voltage within the sensor electronics. Each voltage value can be assigned to a specific angle value.

Depending on the requirements and customers’ requests, ZF offers a range of different angle sensor variants with associated magnets for triggering signals. These vary in terms of the angular range (0-360°), signal redundancy (non-, semi- or fully redundant), connection interface (cable, connector), operating temperature range and form factor. Attributed to long lasting experiences and know how in hall-based sensor technology, also customized solutions can be fulfilled.

"New compact Magnet Carrier 709-21995 for use with existing Hall-based angle sensors for precise and wear-free angle measurement".

ZF presents its new compact Magnet Carrier 709-21995 for use with existing Hall-based angle sensors for precise and wear-free angle measurement. These are ideal for harsh environments such as in the steering system of forklifts and other off-road vehicles. The combination of the new magnet carrier with the ANG angle sensor offers enormous advantages in limited space due to its small dimensions.

ZF offers several angle sensor variants that differ between the redundancy of the output signal: non-, semi or full redundancy, (primarily for safety requirements), the measuring angle and the cable connection and connector type. These variants support flexible use in individual application areas of angle detection. The ANG sensor is the newest in the ZF angle position sensing portfolio. With its length of 3.2 cm and width of 4.5 cm, it fulfills strict requirements in respect of limited space in customer applications and has an extended temperature range (-40 to 140°C), high accuracy (+/- 2% to +/- 2.5%) and is rated IP68. Depending on the desired security, the ANG angle sensor is available in a simple version with three cable outputs but without a redundant output signal, or with four cables and a semi-redundant output signal.

The brand new and extremely compact magnetic carrier from ZF is ideally suited for combination with angle sensors over a measuring range of up to 360°. It works perfectly in conjunction with the ZF Hall sensors. The plastic carrier housing contains a rare earth magnet consisting of a samarium-cobalt compound. It is equipped with two brass bushings to attach the magnet carrier to the target object reliably. The magnet carrier has primarily been designed to serve applications with limited space. It is only 2.4 cm long and 1.8 cm high.

An application example is electric steering (steer by wire) in forklifts, one that ZF sensors and magnet carriers are already well established. The target is for the precise implementation of the desired steering angle from the driver to be communicated to the vehicle. The small magnet carrier is mechanically attached to the steering axle with M3 screws and rotates without contact. It is therefore wear-free over the Hall element of the sensor.
