Sensata (Cynergy3) FLPV Series Float Switch

 Cynergy3_logo.jpg

Sensasta (Cynergy3) are pleased to announce the launch of the FLPV Series of Float Switches from our Level and Flow product line to our Global Distribution Network.

The FLPV is a flameproof vertical float switch range, with single or dual float, designed to give the user a long reach with a number of switching options, catering to a wide variety of system requirements. Manufactured in stainless steel 316L material, these ATEX and PED certified switches are suitable use in many aggressive liquids or hygienic applications.

Their industry standard process connection sizes give a quick and reliable method of installation:
• Dual switch point for high/low indication
• Stainless Steel 316L material
• Fast switching, allowing precise control
• High life expectancy

Wherever there is a need to detect the level of fluid there may be a requirement for a level switch. To list all areas where this is applicable to the FLPV is prohibitive. However, the FLPV will be used as either
a process control device or system protection device. The FLPV is a reliable and robust switch due to its design and more cost effective compared to its competitors.

Typical examples of usage include storage overfill protection, pump run dry protection, and max-min level control. The FLPV Series is a great solution to address these requirements:
• Power ratings 10 VA
• Fast switching, allowing precise control
• Switching Voltage 200VAC / 120VDC
• High life expectancy
• 10 Bar Pressure rating

ZF’s New Compact Magnet Carrier Ideal For Harsh Environments

“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.

Schurter UMT-H Fuse Family: Extension 40A and 50A

Schurter Logo1.jpg

SMD Ceramic Fuse with Very High Breaking Capacity
• 26 rated currents from 0.16 to 50 A
• International approvals
• Time-Lag T characteristic
• Impermeable to potting compound

The well introduced SMD ceramic fuses of the UMT-H family have been expanded in the form of a 40 A and a 50 A version. Schurter now offers the UMT-H with its Time-Lag T characteristic in a total of 26 rated currents between 160 mA and 50 A.

The UMT-H SMD ceramic fuse now covers a current range from 160 mA to 50 A at voltages of up to 277 VAC and 250 VDC. This makes the cuboid fuse ideal for cost-efficient automated assembly. Its large solder pads ensure excellent heat dissipation.

Applications
The UMT-H was specially developed for primary protection in industrial electronics at nominal voltages of up to 277 VAC. Additional areas of application are energy supply, medical technology and telecommunications as well as e-mobility. New market developments show that currents of 40 A and 50 A are increasingly needed for battery-powered applications.

High Inrush Currents
The UMT-H is predestined for use in applications with high inrush currents (e.g. motors) due to its Time-Lag T characteristic. But also newer applications, which increasingly rely on powerful accumulators, often require slow tripping.

Impermeable to Potting Compound
The UMT-H remains tight with most commercially available potting compounds. Therefore, this fuse is especially suitable for high demands. In addition, the high breaking capacity of 1500 A and the cap distance of >10 mm make the UMT-H the ideal choice for explosion protection.
