Product details

Right-Angle, 4-Pin SL Header with Latch Retention

The 171974-0104: The polarizing key ensures the mating half cannot be inserted incorrectly.

For continuous operation near the 105°C upper limit, derate the current per the manufacturer's curve — the 3A rating is at 25°C ambient.

This header mates with Molex SL series crimp housings (e.g., 70066 series) that accept 22-26 AWG wire with the matching crimp terminals. The 0.240" (6.10mm) mating pin length provides good contact wipe on insertion. The through-hole leads are 0.025" square, compatible with most wave-solder processes.
