PBH Push-Pull Circular Connectors, 5 and 7 Contacts
Push-pull · 5 or 7 contacts · vibration to 5000 Hz
Y27 Sealed Push-Pull Circular Connectors, up to 121 Contacts
Push-pull · 1–121 contacts · 2 m immersion · hermetic receptacles
Y27 combines straight push-in mating with a latching lock, so connectors mate blind and release with a pull on the sleeve or a lanyard. Seven sub-series cover 70 layouts from one 12 mm power contact to 121 signal contacts, with contacts from Ø0.8 mm (3 A) to Ø12 mm (250 A). Y27F, G and H are immersion-proof to 2 m, and receptacles can be rubber-sealed or glass-sealed.

Frequently asked questions
How does the push-pull lock work?
Push the plug straight in and it latches automatically. To release, pull the outer sleeve, or on pull-away plugs the lanyard, and the plug disconnects without rotation.
Which versions are waterproof?
Y27F, Y27G and Y27H are immersion-proof to 2 m. For sealed enclosures choose a rubber-sealed or glass-sealed receptacle.
