62-Position High-Density D-Sub — Right-Angle, Board-Locked
The TE 2311771-1 is a 62-position, 3-row high-density D-sub receptacle from the AMPLIMITE HD-22 series, designed for signal-level interconnects in equipment that needs a dense I/O footprint. Board locks on the shell hold the connector down during wave solder and resist shear from cable strain — without them, the reflow or rework cycle can lift the connector off the board, opening solder joints on the inner rows.
3 A Signal Duty and 30 µ" Gold — What That Means for the Fit
Rated 3 A per contact, this is a signal-grade connector — not a power interconnect.
Board Lock and 4-40 Flange — Mechanical Retention Details
The 4-40 threaded flange is the standard D-sub mounting pattern — mates with any standard D-sub backshell or panel-mount hardware. The board lock is a pair of metal tabs that solder into plated through-holes on the PCB, providing a mechanical anchor that resists the lever force from the cable assembly. In a right-angle mount, the board lock is especially important because the cable exit direction applies a moment at the solder tails; without it, the outer rows of pins can crack under repeated flexing.
