The P101 is a durable, affordable, high accuracy stand alone linear inductive position sensor designed for use in scientific and industrial applications.

Like all Positek sensors the P101 provides a linear output that is proportional to the displacement. The P101 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 10" (254 mm) measurement then Positek will manufacture the sensor specifically for this length.The mechanical length and calibration will be set up for 254 mm.the P101 is available with any travel from 0-5mm to 0-800mm.

The overall performance, repeat-ability and stability are outstanding over a wide temperature range. The sensor is very robust, manufactured from stainless steel the P101 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 P101 is easy to install with either M5 rod eye or body clamps. The push rod can be supplied captive or free with either M5 thread, M5 rod eye or ball end. The rod can be spring loaded if required in either direction on sensors with a stroke length of up to 300mm. The P101 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.

Positek offers a range of options for its standard sensors. Each sensor is manufactured to suit each customer's preferences. If your requirement is outside the options given below, Positek can modify/ redesign a sensor to suit your specific requirement. Standard options are available as below:


Measurement Range

Factory set to any length from 0-5mm to 0-800mm in increments of 1mm. For example, if your application requires 10" (254 mm) measurement, then Positek will manufacture the sensor specifically for this length. The mechanical length and calibration will be set up for 254 mm.
