The Molex 50‑57‑9403 is a versatile three‑pole, single‑row crimp receptacle housing in black polyester, designed with a 2.54 mm (0.100″) pitch and integrated latch for reliable cable-to-board connections. This compact connector housing supports currents up to 3 A and voltages up to 250 VAC/DC. Engineered to meet UL 94 V‑0 flammability standards and operating from –40 °C to +105 °C, it is perfect for global deployment across environments. Its robust latch, RoHS compliance, and universal compatibility make it an ideal option for electronics manufacturers and system integrators worldwide.

What Sets the Molex 3-Pole, Single Row Crimp Receptacle Housing Apart?

Uniquely suited for reliable and cost-efficient wire‑to‑board connections in signal and low‑power applications, it ensures secure retention via its positive latch while simplifying assembly with standard SL crimp terminals (e.g., 70058, 71851). With UL 94 V‑0 insulation, wide temperature range, and high manufacturing stock availability, this connector housing delivers durable performance in industrial, commercial, and consumer electronics across diverse markets.
