The P103 is a durable, affordable, high accuracy short stroke linear inductive position sensor designed for use in industrial and scientific applications. It is very compact and offers an excellent stroke to overall length ratio. Each unit is supplied calibrated to the exact travel required by the customer, for example, if your application requires 1" (25 mm) measurement then Positek will manufacture the sensor specifically for this length.The mechanical length and calibration will be set up for 25mm. The P103 is available with any travel from 0-2mm to 0-50mm.
The overall performance, repeat-ability and stability are outstanding over a wide temperature range. The sensor has a rugged stainless steel body and plunger.
The P103 sensor is particularly easy to install with either flanged housing or body clamps. The plunger can be supplied captive or free with either female M4 thread or spring loaded with dome end. The P103 is available with a wide range of electrical inputs/outputs, sealing up to IP65/IP67 dependent on connector/cable options and fully integrated EMC protection.
