About the H138 Linear Inductive Position Sensor

The H138 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 incorperated electronics system is CSA approved for use in potentially explosive gas/vapour and dust atmospheres.

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 sensor has a compact 19mm 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 25mm pitch. The stainless steel plunger can be supplied free or captive, with female M4 thread, or spring-loaded with a ball end. Environmental sealing is to IP67.

As a leading supplier of linear, rotary, tilt and intrinsically safe position sensors, Althen has the expertise to supply a sensor to suit a wide variety of applications.
