MALVERN, PA — Vishay Intertechnology (NYSE: VSH) has introduced a multi-turn absolute position sensor aimed at industrial motion-control and automation applications, expanding its sensing portfolio with a device the company said offers lower cost, high accuracy and long operating life.
The company announced the Vishay Sfernice 34 PHE, a ready-to-use, non-contact Hall Effect position sensor designed for linear and rotary displacement tracking in industrial equipment, agricultural machinery, railway systems, marine applications and solar panel tracking systems.
The sensor provides a total electrical angle of 3,600 degrees across 10 turns, with linearity of up to ±1% over the full stroke, 1-degree resolution and a lifespan exceeding 10 million operating cycles. Vishay said the device is priced about 40% below previous-generation models.
The company noted that the sensor is intended for applications including industrial motors and actuators, flow-control valves, throttle and pedal position sensing, and servo-loop motion control systems.
To withstand demanding operating conditions, the device features IP65-rated sealing, vibration resistance up to 20 g and shock resistance up to 50 g. Integrated reverse-voltage and overvoltage protection eliminates the need for external protection circuitry, while optional dual analog or pulse-width modulation outputs provide built-in fault detection for safety-critical applications, according to the company.
Vishay stated that the sensor reports its position immediately after power is restored without requiring recalibration or initialization, eliminating the need for battery backup systems. The RoHS-compliant device operates from a 5-volt DC power supply and is available with configurable analog or digital output options.
