The TE Connectivity 2214934-3 is a 12-position female card edge connector from the MULTI-BEAM CE series, designed for dual-readout on a 0.062" (1.57mm) thick PCB edge. The black glass-filled thermoplastic housing provides the mechanical rigidity needed for a card-edge interface in power distribution or backplane applications.
The 12-position count matches a 12-circuit BOM line — each position contacts one trace on the PCB edge. The 0.062" card thickness spec is non-negotiable: the connector's contact beam geometry is set for that PCB thickness, and a thicker or thinner board will not seat correctly or maintain contact force. The dual-readout design means the connector contacts both sides of the PCB edge, doubling the effective contact density per card slot. The copper alloy base metal under the gold gives good spring properties for the contact beams.
Through-hole solder termination means the connector pins go through plated holes in the motherboard and are wave-soldered or hand-soldered in place. This gives a stronger mechanical anchor than surface-mount for a card-edge connector that sees insertion and extraction forces. The two-row layout (12 positions across two rows) keeps the connector footprint compact while maintaining the dual-readout contact pattern.
