PSCM

Rotary Multiturn Hall-Effect Position Sensor

The PSCM is a non-contact multiturn angular position sensor based on Hall-effect technology and a cost-effective replacement for absolute encoders. It is also perfectly suited to substitute wire actuated sensors by translating a linear movement into angular position. In the event of a power loss, the sensor will preserve the last measured position.

This compact and rugged sensor is configurable with angular ranges between 720 and 11.520 degrees (up to 32 revolutions) and support for low and high-voltage power supply. The PSCM offers a standard absolute linearity of 1%, which can be customized upon request to 0.1% for applications requiring high accuracy.

The high level of ingress protection, vibration and temperature resistance makes this magnetic sensor well suited for extreme environments of industrial, off-highway, marine and transportation applications. Wire and connector assemblies are available on request.

KEY FEATURES



Without any gears or mechanical interfaces the sensor is easily assembled and calibrated and subject to limited wear and tear over lifetime.
Keeps the last position on power loss with configurable electrical angles from 720 to 11.520 degrees.
The rugged package protects the sensor from dust, moisture, vibration and extreme temperatures for usage in the most demanding environments.
The non-contacting design allows for an extra-long product lifetime of up to 50 million cycles.
Programmable transfer function and switch outputs as well as different output protocols and redundancy levels available
The magnet is securely fastened to the shaft and acts as only moving component in the sensor.

4 Please note: Sensor saves last position if power is turned off, but does not count turns if not powered. For applications where the shaft may rotate while the system is not powered and the customer requires a true power-on absolute multi-turn position, Piher can also use an alternative non-contact multi-turn architecture based designed to record rotations of a magnetic system even while powered down and report the absolute position at power-up through. It supports more than 16,000°, and combines turn counting with angle sensing for absolute multi-turn position feedback that is an ideal fit for for applications such as boat lifts, actuators, winches, valves, hoists, and other equipment where the shaft can move without power and the control unit must recover the true position when power returns.
