P501 Rotary Inductive Position Sensor

Durable, high-accuracy miniature sensor calibrated between 30-140 degrees

About the P501 Rotary Inductive Position Sensor

The P501 is an affordable, durable, high-accuracy rotary sensor designed for industrial and scientific feedback applications, but requires a smaller footprint than the P500.

The sensor is supplied with the output calibrated to the angle required, between 30 and 140 degrees and with full EMC protection built in. The P501 provides a linear output propertional with input shaft rotation. There is a machined registration mark to identify the calibrated mid point.

It is particularly suitable for OEM's seeking good sensor performance for applications where space is important.

Overall performance, repeatability and stability are outstanding over a wide temperature range. The P501 has a rugged nickel plated aluminium body and integrated mounting flange. The flange has two 4.3mm by 20 degree wide slots on a 48mm pitch to simplify mounting and position adjustment. Environmental sealing is to IP67 on the cable version.

Features P501

  • Non-contacting inductive technology to eliminate wear
  • Angle set to customer’s requirement
  • Compact, durable and reliable
  • High accuracy and stability
  • Sealing to IP67
