Contrinex Inc. (www.contrinex.com) engineered its new sensors to withstand weld spatter and resist electromagnetic field interference in induction welding and hardening plants. The company says these sensors are sealed to the IP67 (ingress protection) standard and are Teflon-coated to withstand weld spatter and resist electromagnetic field interference. These sensors are available in M12, M18, M30 and C44 formats, and have identical operating distance on aluminum, brass and other non-ferrous metals.
