P118 Slim-line, Short stroke Linear Position Sensor.


Position feedback for industrial and scientific applications
Available in any travel from 2mm to 50mm.

Our P118 LIPS® (Linear Inductive Position Sensor) is an affordable, durable, accurate position sensor designed for a wide range of industrial applications. It is particularly suitable for OEMs seeking good sensor performance in situations where a small diameter, short-bodied sensor is needed and cost is important. The unit is compact and space-efficient, being responsive along almost its entire length, and like all Positek® sensors provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 2mm to 50mm and with full EMC protection built in. Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor has a compact 19 mm diameter stainless steel body, is easy to install and set up. Mounting options include body clamps or a stainless steel mounting flange with two 3.2 mm by 30 degree wide slots on a 25 mm pitch. The stainless steel plunger can be supplied free or captive, with female M4 thread, or spring-loaded with a ball end. The P118 also offers a range of mechanical options, environmental sealing is to IP67.
