David Phillips, binder UK, provides a guide to some key developments in M12 sensor connectors

12 connectors have become the de-facto standard for automation

applications and are most commonly used for sensors monitoring measurement and safety systems. These connectors are tough, can be shielded, and are normally waterproof to IP67.

M12 GOES OUTDOORS Originally intended for indoor applications, M12 connectors are now being used successfully on outdoor equipment where field attachable versions are generally rated to IP67, and moulded versions and receptacles to IP68, making them suitable for wet and dirty conditions. In extreme conditions, such as those in the off-shore oil and gas industry, where resistance to ice, snow, salt spray, UV and ozone is required, binder’s latest M12 connectors feature a UV plastic body and high-grade stainless steel to provide high temperature and chemical

resistance. Polymeric seals ensure protection to IP69K and a tough protection cap with lanyard ensures sealing even when unmated.

Connectors for difficult environments M

FOOD AND BEVERAGE SECTOR To meet the more stringent hygiene requirements for systems and components in the food and beverage sector, the new binder connectors, designed specifically for this sector, are M12 A-coded connectors for applications in all types of industrial food processing. This includes dairies, abattoirs, bottling plants and food storage, and will also find use in the pharmaceutical and chemical industries. High-quality materials such as stainless

steel and special plastics are used with smooth contours to prevent dirt adhesion. Protection to IP68 and IP69K is provided to meet with the requirements of high pressure cleaning with aggressive chemicals.

M12 for the food and beverage industry

The new range includes male and

female cable connectors and moulded leads in cream-coloured RAL 9001 polypropylene, on grey PVC jacketed cables. This specification ensures that these versions not only look different from the standard connectors, but the light-coloured surface means dirt and residue are easy to see. The sensors of tomorrow will be

required to operate in ever more difficult conditions with protection from harsh environments and aggressive chemicals. binder are only too aware of the need to develop connectors to match.
