UL* Straight plug with lanyard release, alignment key and arc-shape metal guides, prevent vibration.
1. UL Straight Plug with Lanyard Release brief introduction:
The U series connector is a push-pull self-locking connector that combines the multi-key position and multi-positioning structure derived from the B-series positioning pin structure and the F-series semi-circular positioning structure. The connector is mainly used for low-frequency signal transmission in electronic equipment. Easy operation, good shielding effect, good sealing, three-key positioning and semi-circular positioning double anti-misinsertion, solid shell, anti-electromagnetic interference, good environmental resistance, long service life and other characteristics. Widely used in medical machinery, communication systems, computers, small communications and other equipment.
Making it an ideal choice for Medical, Test & Measurement, Research, Communications, Broadcast Connector, Machines, Defense, Robotic, Aerospace, public sector, Information Systems, Motorsport, Miscellaneous applications.
