A-BL127-DG-G68MP1

Overview

The Assmann WSW Components A-BL127-DG-G68MP1 is a 127-pin, 0.5mm pitch, right-angle through-hole board-to-board connector designed for high-density electronic assemblies. It features a dual-row configuration with 68 contacts per row and an overall height of 3.9mm. The connector utilizes gold-plated phosphor bronze contacts to ensure reliable signal transmission and low contact resistance. Constructed with UL94V-0 rated PBT plastic housing, it supports surface mount technology (SMT) reflow soldering processes. Rated for 1A current and 300V voltage, this component provides secure mechanical locking and stable electrical performance in compact consumer electronics and industrial applications requiring robust interconnectivity.

Procurement Notes

Verify the specific contact plating thickness and housing color options against the manufacturer's latest datasheet before finalizing orders. Ensure that the selected variant matches the required operating temperature range and mechanical locking specifications. Confirm compliance with RoHS directives and check for any recent updates regarding lead-free soldering compatibility. Cross-reference the pin count and pitch dimensions with the target PCB footprint to prevent assembly errors during procurement.

Selection Notes

Select this connector when a high-pin-count, low-profile solution is required for vertical mating between two printed circuit boards. The 0.5mm pitch allows for significant I/O density within a constrained area. Consider the right-angle orientation if space constraints prevent horizontal alignment. Evaluate the current rating and voltage withstand capabilities against the system's electrical requirements to ensure long-term reliability under operational stress conditions.
