Board-to-Cable Header for Power and Signal Duty
The 640901-1 is a 5-position, single-row header from TE's Universal MATE-N-LOK series, designed for board-to-cable/wire applications where a reliable locking interface is needed. The 0.250" (6.35mm) pitch provides ample spacing for routing larger-gauge wire and maintaining creepage distances at higher voltages, a step up from the 0.100" or 0.156" pitch used in signal-only connectors. The locking ramp fastening type ensures the mated connector pair stays together under vibration or cable strain — a practical feature for industrial equipment, power supplies, and appliance wiring where an accidental disconnect means downtime.
Through-Hole Termination and Material Choices
Termination is through-hole solder, with a post length of 0.155" (3.94mm) — a standard length for single-sided or double-sided PCBs with plated through-holes. Contacts are phosphor bronze with tin plating on both the mating surface and the solder post. Tin is a cost-effective choice for moderate mating-cycle applications. The housing is molded from polyamide (nylon) with a UL94 V-0 flammability rating, meeting the flame-retardant requirement for equipment installed inside enclosures.
Operating Range and Compliance
Rated for an operating temperature range of -40°C to 105°C, this header suits applications in industrial cabinets, outdoor telecom gear, and automotive interior environments where the ambient temperature stays within that window. The product status is Active, with no end-of-life notice. Sourced and quoted to order against the BOM quantity — confirm the mating half and position count before committing.
