Contrinex offers analogue photoelectric sensors

A Contrinex UK product story
Edited by the Engineeringtalk editorial team Mar 12, 2009

A range of rectangular photoelectric sensors with analogue output is available from Contrinex.

The long sensing ranges and analogue output allow multiple decisions to be made from a single Contrinex sensor enabling smarter control of processes.

Characterised by a sensing range from 10 to 100mm, excellent temperature stability and outstanding repeat accuracy these sensors are ideal for discerning different components by their size or features from a single sensing location.

An automotive customer uses the Contrinex analogue sensors to identify the difference between three different steering struts on a production line.

The struts all have similar features but slightly different lengths, which the Contrinex sensor is accurate enough to detect.

Despite the harsh manufacturing environment, the sensors reliably ensure that all struts are correctly identified and processed.

Other applications include, slow down commands on a transfer line, variable displacement of gates, deflectors and guides on conveyors, stack height feedback, hopper fill levels for liquids or powders, product verification for a single and not a double product check, plus many more options.

The analogue sensing range is independent of the target colour or surface structure and, as the output signal is not digitised, the accuracy of the resolution is virtually unlimited.

These Contrinex analogue sensors are stabilised for temperatures from -25 to +55C and remain accurate once installed.

The sensors have both voltage and current outputs and a high-speed response that provides users with system flexibility.

All sensors in this range are fully potted, come in a tough 30mm x 30mm x 15mm housing and are protected to IP 67.
