Product Details Supplier Info More products

Variohm Eurosensor has launched a range of potentiometric linear position sensors for precision measurement from 10mm to 300mm.

The sensors are supplied in open housings, reducing component cost for high-accuracy position feedback applications.

The PTP series from Novotechnik is a two-part design including a multi-fingered wiper assembly and a separate open-sided extruded aluminium housing containing a conductive plastic track.

This design facilitates mounting to equipment where sealing against dust or fluid is not necessary or where customers are able to integrate these component parts within their own sealing arrangements.

The PTP series also allows for a variety of feature customisation suitable for high-volume applications.

The extruded housing has a cross section of 13 x 9.6mm and includes longitudinal slots for mounting with optional fixing clamps or alternative fixing available via pre-drilled holes.

The inner profile provides a rigid, low-friction bearing surface for the wiper assembly, which includes threaded-hole, follower-pin and rod-driving options.

The conductive plastic resistance elements comprise multiple printed layers using Novotechnik’s own specialised conductive inks in combination with multi-fingered precious-metal wipers featuring an elastomer damping mechanism to maintain complete contact, even under demanding working conditions.

The PTP series specification includes a typical life of 50 million movements, with a vibration rating to 20G at 2,000Hz and shock to 50G.

With a speed capability to 10m/sec, repeatability to 0.01mm and linearity to +/-0.05 per cent, these sensors are aimed at high-accuracy and high-reliability position measurement in clean environment applications or within customer-sealed housings.

The PTP series is part of a range of Novotechnik contacting and non-contacting angular position sensors available exclusively in the UK and Ireland from Variohm Eurosensor.

Novotechnik’s conductive plastic technology is proven across large-volume industrial and automotive applications for both rotary and linear position measurement in fully sealed and open designs, with numerous mounting styles and grades of precision including dual-redundancy versions and with customisation readily available to suit specialised applications.
