E138 Linear Inductive Position Sensor

Compact and space-efficient

About the E138 Linear Inductive Position Sensor

The E138 is designed for a wide range of industrial applications and is ideal for OEMs seeking good sensor performance in situations where a small diameter, short-bodied sensor is required for operation in hazardous areas.

The unit is compact and space-efficient, being responsive along almost its entire length.

Overall performance, repeatability and stability are outstanding over a wide temperature range. It provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 51mm to 100mm and with full EMC protection built in.

The E138 is easy to install and set up, the stainless steel mounting flange has two 3.2mm by 30 degree wide slots on a 25mm pitch. The stainless steel plunger can be supplied free or captive, with female M4 thread, or springloaded with a ball end. It also offers a range of mechanical options. Environmental sealing is to IP67.
