0B series Push-pull self-lock Connectors have a very simple locking mechanism:
As the plug is pushed into the receptacle, locking fingers on the plug snap into the receptacle,
creating a reliable connection between plug and receptacle.
Pulling on the cable or the rear of plug causes the locking fingers to grab harder and a separation of plug and receptacle is almost impossible.
Pulling on the outer plug housing causes the locking fingers to retract and the plug and receptacle separate easily.

The Advantages of Push-Pull-Connectors:
* Quick and easy mating and demating
* Quick and easy separating
* Easy blind mating in difficult-to-reach places
* Less panel space required
* Definite and secure locking condition
* Less mating required
* Easy cleaning of housing possible
Important Applications for Push-Pull Connectors:
* Surveying
* Medical Electronics
* Test and Laboratory
* Measurement Instrumentation
* Data and Telecom Systems
* Audio and Video Applications
* Military and Aerospace
* Industrial Controls
* computer automation measurement
* To specify a connector, you'll need to determine the style, size, contact configuration, cable collect, and the options you desire.
