Product details

Glow wire compliance per IEC 60695-2-11 means this header can be used in lighting and industrial equipment where a glowing heating element must not sustain ignition.

Current, Voltage, and Contact Finish

In a lighting fixture that is mated once at installation, this is not a limitation. The 0.303" (7.70 mm) mating length provides enough wipe for the receptacle contact to clean the tin surface on insertion. Above 85°C ambient, derate the 7.5 A per the housing material curve — the polyamide (nylon) loses mechanical strength as it approaches its continuous-use ceiling.

Frequently asked questions

What is the mating connector for 1744489-3?
