Yamaichi Electronics' IEC 61076-2-012 compliant Y-Circ M system is IP65 / IP67 waterproof and dustproof and uses independent sealing concepts for screw and push-pull connectors, as both the socket and mating connector are equipped with their own standard O-rings to ensure effective sealing. When the push-pull socket is mated with an M12 threaded connector, sealing is achieved by an O-ring at the bottom of the socket, which is activated by a precise torque. However, when the M12 push-pull is used as a cable connector, it has its own O-ring that seals the collar of the receptacle, thus preventing ingress of media at an early stage.
Another advantage is the use of standard O-rings. Unlike form sealings, these are available worldwide without tooling costs. The use of standard O-rings also allows automatic assembly when integrating the insulators into customer housings.
Flexible switch between push-pull and screw locking
An outstanding feature of the Y-Circ M is the ability to switch flexibly between push-pull and screw locking without compromising sealing. This is because the seals are not worn by the other system during mixed mating cycles, but retain their full sealing effect.
This allows flexible switching between locking types for up to 100 specified mating cycles, guaranteed by the manufacturer, while maintaining full sealing performance. This flexibility is particularly beneficial in applications where different locking systems are used without compromising the reliability of the connection.
This forward-thinking design also allows the manufacturer to make their device "push-pull ready" and still use the classic screw locking system if required.
