In this video from our archives, Design World’s Senior Editor Miles Budimir and I discuss Fischer Connectors’ Core series of circular push-pull connectors, which use a tough locking mechanism to keep them securely attached to the devices and cables they are connecting.
The push-pull feature means these connectors are tough and cannot be accidentally disconnected. They require a purposeful disconnection, so they are ideal in applications where an accidental disconnection can be dangerous.
The Core series of push-pull connectors comes in brass, aluminum, plastic and stainless steel, the newest design. It has been designed for extreme environments–such as nuclear and energy, medical, and food processing applications. They offer high chemical, temperature and radiation resistance.
And what’s cool about the Core series is all the different materials can work together. For example, medical devices may use a nickel-plated brass receptacle on the box, and use a plastic or disposable on the hand-held device. Or someone might choose stainless steel for washdown or sterilization.
Additionally, all Core series push-pull connectors use what Fischer calls its half moon keying. This prevents a user from damaging a connector if they try to put a plug into the wrong receptacle. It also prevents you from actually mating something that shouldn’t be mated. Fischer has four standard “keys” that it uses, and can also build custom keys.
Other standard options include colored rings and overmolds to color code plugs to receptacles, which also helps in identifying correct mates.
The Core connector series was originally established in 1954. The series has various sealing levels from IP50 to IP68/69, and ranges from quick release short plugs to hermetic bulkhead feedthroughs or completely threaded receptacles with PCB contacts. In fact there are 35 different body styles.
