Specialist Recommends: Attend’s All-Plastic Connectors with Bayonet Locking

Round industrial connectors Attend, Series 227

Connectors with a bayonet locking system are circular connectors that allow for quick and secure connections, resistant to unintentional disconnection during vibrations. For many applications in the industry, they represent an ideal solution for interconnecting devices. 

"When it comes to industrial connectors from the Attend brand, I was pleasantly surprised by the high-quality all-plastic design and the bayonet lock. Unlike connectors secured against disconnection by screws, these connectors feature a bayonet locking system. It's a simple, fast, and reliable solution, so even when the devices vibrate, these connectors won't loosen spontaneously. Moreover, these connectors can be conveniently attached to or detached from a device with just one hand," says František Ďuríšek, Product Specialist at SOS electronic.  

We have added Attend‘s bayonet connectors of Series 227A, 227B, 227C, and 227D to the SOS electronic assortment, differing in dimensions, pin count (from 2 to 25), and current load capacity of contacts up to 20 A.

Marking of Attend’s bayonet connectors of Series 227

However, the method of connection (to panel, cable, PCB) is not unambiguously indicated in the name, so we recommend always verifying the specific connector on our website or directly on the Attend manufacturer's web page.

Based on basic parameters, we classify Attend's round industrial connectors as follows:
