M12 cordsets with a corrosion-resistant coupling nut are a cost effective alternative to stainless steel or even nickel plated brass. The polyamide (plastic) nut is resistant to many industrial chemicals such as acetone, ammonia, benzene, brake fluid, diesel fuel, gasoline, engine and gear oil. The molded cordsets use a PUR halogen-free cable which is environmentally friendly and have a water tight seal meeting IP65/ 68/ 69K classification. On the receptacle side, either pcb mount or panel feed through connections are possible with wave solder pins, solder cups, flying leads. A nut is included with the connectors to fasten the receptacle to the device wall.
