ZF E-Bike Speed Sensor GS82-AA02, Targets High Resolution of Signal

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.

Schurter EC12 Snap-In Appliance Inlet with Filter and Mains Switch

Schurter Logo1.jpg

IEC C20 Appliance Inlet with Filter and Mains Switch
• Compact Power Entry Module with Filter
• Optionally with Enhanced Surge Withstand Voltage
• V-Lock Cord Retention

Schurter expands the successful EC12 appliance inlet filter family with new variants for snap-in mounting. This allows the compact power entry module to be mounted even faster and easier.

The EC12 filter series combines an IEC C20 appliance inlet with a high quality 1-stage filter and power switch.

Snap-In Mounting:
New variants of the EC12 power entry modules feature two snap-in springs instead of the screw flange for even simpler and more efficient installation. Thanks to the high-quality springs, a tight-fitting installation is ensured with good electrical contacting of the mounting panel at the same time. The wide metal flange contacts the housing over a large surface area, thus enabling optimum filtering and shielding effect.

Applications:
The EC12 filter series is available as a standard or medical version and is used in devices that require particularly high resistance to interference. This includes IT or telecom systems according to IEC 92368-1 and medical equipment according to IEC 60601-1.

Filter versions with increased surge withstand voltage capability are also available. These have interference suppression capacitors of safety class X1 for surge voltages of 4 kV between L and N and Y1 for surge voltages of 8 kV.

The series is compatible with V-Lock cord retention device connection cables. The EC12 series is certified for currents up to 16 A/250 VAC according to IEC and 20 A according to UL/CSA at 125/250 VAC. It comes with ENEC, CQC and cURus approvals.
