P112 Linear Position Sensor

The Positek P112 linear position sensor is a very compact, durable, affordable, high accuracy linear inductive position sensor with a good stroke to overall length ratio; designed for gauge head positioning in scientific and industrial applications.

Like all Positek® sensors, the P112 provides a linear output that is proportional to the displacement. Each unit is supplied calibrated to the exact travel required by the customer, the P112 is available with any travel from 0-5mm to 0-50mm. For example, if your application requires 3/4″ (19 mm) measurement then Positek will manufacture the sensor specifically for this length. The calibration will be set up for 19 mm. The overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is very robust, manufactured from stainless steel the P112 has a long service life and strong environmental resistance and is particularly suitable for applications that require good sensor performance in harsh environments such as industrial machinery where cost is important.

The P112 has a spring loaded plunger with a dome end and the body has a long 1/2″ UNF mounting thread and is supplied with two lock nuts for positioning. Sealing is IP67 and the P112 has fully integrated EMC protection.
