Miniature Circular Waterproof Shielded Connector (Bayonet Lock Type), LF Series

Brand :

HIROSE ELECTRIC

Caution

Product Description

This is a small waterproof round connector. The structure makes the shield connection and connector assembly easy, and the bayonet lock also makes attaching and detaching it simple.

[Features]
・Easily connected shielded wire: The cable's shielded wire is fixed to the outside of the cable using metal fittings attached to the connector, which makes it easy to connect to the connector shell.
・Waterproof structure: The waterproofing performance is IP67 in the connector fitted state.
・The connector does not use small screws, so the structure is simple.
・Bio-Net Lock: The lock has good operability, and has a strong, vibration-resistant structure.
・Safety standards are met.
・4 cores at 10 A comply with overseas safety standards (TUV).
・In addition, 3 cores and 4 cores comply with UL standards.
