M50-3123345

Headers, Receptacles, Female Sockets Overview

The M50-3123345 is a rectangular connector receptacle from the Harwin Archer M50 series, designed for board-to-board or cable-to-board applications. It features a dual-in-line configuration with 66 positions arranged in two rows of 33 contacts each. The connector utilizes a 1.27 mm (0.05 inch) pitch and employs a push-pull mating mechanism to ensure secure engagement. Contacts are made of phosphor bronze with gold plating, rated for 1 A current at 300 V. The housing is constructed from black polybutylene terephthalate (PBT), offering UL 94 V-0 flammability rating. Designed for through-hole solder termination, it operates within a temperature range of -40°C to +105°C.

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific part number matches the required 66-position count and dual-row layout before ordering. Confirm that the PCB footprint supports the through-hole soldering process and aligns with the 1.27 mm pitch specification. Ensure that the assembly environment accommodates the push-pull mating force requirements. Check for any updated RoHS compliance documentation if operating in regulated regions. Validate that the cable assembly used provides sufficient insulation for the 300 V rating.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a robust, high-density connection is required between rigid boards and flexible ribbon cables. The push-pull feature distinguishes it from standard IDC connectors by providing mechanical security without additional latches. Consider the 1.27 mm pitch as a balance between density and manufacturability. The gold plating ensures low contact resistance over repeated cycles. Evaluate the thermal performance of the PBT housing against the operational environment's maximum temperature limits.

Headers, Receptacles, Female Sockets Part Context

This connector belongs to the Archer M50 series, a family of high-reliability interconnect solutions known for their compact form factor and durable construction. The series is widely utilized in demanding environments where vibration resistance and consistent electrical performance are critical. The M50-3123345 specifically addresses the need for higher pin counts in a dual-row format, facilitating complex signal routing in space-constrained designs.
