TE Connectivity – 3A-rated signal connectors provide secure mechanical termination


TE Connectivity’s Signal Double Lock connectors have a 2.5mm centreline pitch and are available in both wire-to-wire and wire-to-board configurations.

This large family of compact, single-row connectors accepts wire sizes between 26 AWG and 20 AWG with insulation diameters as large as 1.8 mm.

The Signal Double Lock connector system consists of plug and cap housings for wire termination, optional double lock plates, crimp contacts and PCB pin headers in both standard and high-profile versions. Double-lock plates ensure positive loading of contacts in the housing, and prevent contacts from being mated half-way. The connector makes an audible click when the contact is fully inserted into the housing.

TE has extended the family of Signal Double Lock connectors to include parts made in material that meets the glow wire test according to the IEC 60335-1 5th edition standard for household and similar appliances, and that conforms to the specifications of UL 94 V-0.
