The Amphenol 87052-444HLF is a dual-row, 0.100-inch pitch (2.54 mm) male board-to-board header in the BERGSTIK II series, populated with 44 positions across two rows. Tin-plated phosphor bronze contacts are rated 5 A per circuit, and the push-pull push-pull fastening type provides a tactile retention feel that is common for this series — unshrouded, so the mating receptacle must be keyed or polarised if mis-mate prevention is required. Through-hole termination suits wave or hand-solder assembly in industrial control and automation applications.
At 44 circuits, this is the high-density end of the standard BERGSTIK II lineup. The 0.100-inch pitch and 5 A per-contact rating are consistent across the series, but the position count is the axis that drives the fit decision — confirm the BOM line calls for 44 positions before committing. All 44 contacts are loaded. The insulation height of 0.100 inch sets the board-stack separation when mated to the matching receptacle.
The 0.100-inch row spacing matches the series standard, which means the footprint is interchangeable with other BERGSTIK II members at the same pitch and row count — verify position count only. Contact finish is tin at 100 µin on the mating face and the solder tail; this is a tin-grade connector suited for standard mating-cycle applications rather than high-cycle or gold-required environments. The 110 V rating governs the voltage envelope for signal and low-power use.
UL94 V-0 flammability rating on the housing material covers the fire-retardance requirement for industrial equipment enclosures. The push-pull fastening type relies on mechanical interference rather than a screw-lock thread, so confirm that vibration levels in the target application do not drive a need for a locked-mating alternative in the same series.
