Weld-immune sensors from Contrinex keep production lines running

It is vital therefore that sensors used in welding applications can survive these arduous conditions and to meet this demand Contrinex makes a rugged range of weld immune sensors in which the operating state does not change, even when they are embedded at the heart of a production welding process.

With thick PTFE sensor faces and tough copper-zinc alloy bodies, the Contrinex welding sensors are sealed to IP67, Teflon coated to withstand weld spatter and are electrically double insulated to resist electromagnetic interference. The range is supplied in M12, M18, M30 and 40mm x 40mm cubic (C44) formats. They are all PNP with a ‘normally open’ output and are fitted with a three-pin industry standard M12 connector. They are also CE approved, have a built-in output status LED and are short circuit, voltage reversal and induction overload protected.

Flush-mountable, they have a sensing distance from 3mm with the M12 up to 15mm with the C44 and all sensors in the range have identical operating distance on aluminium, brass and other non-ferrous metals as on steel. This means that when working with alloy components there is no shortening of sensing distance allowing sufficient clearance from the target to avoid front face damage, the most common form of sensor failure. This is an important feature as the handling and welding of aluminium as well as other alloy components is now becoming almost as common as steel.
