25-Position Right-Angle D-Sub with Board Lock
The TE 1-106507-2 is a 25-position D-Sub receptacle from the AMPLIMITE HD-20 series, configured for right-angle through-hole mounting with integrated board locks. The 25 contacts match the standard DB-25 pinout used in RS-232 serial, parallel printer, and instrumentation cabling — the full-density count, not a high-density 26-position variant. The shell size is 3 (DB, B), and the flange features 4-40 threaded inserts for panel mounting.
Board Layout Fit: Right-Angle Footprint and Panel Mount
The backset spacing of 0.406" (10.30mm) sets the distance from the PCB edge to the panel face — critical for enclosure cutout planning. The 4-40 threaded flanges on the housing/shell require panel clearance for the screw heads; the board locks add two additional through-holes beyond the signal pin grid. The shell material is steel with tin plating, providing EMI shielding when mated to a conductive panel.
Contact Duty and Mating Cycle Life
The 6A per-contact rating at 125V is typical for signal-level D-Sub duty; derate above 105°C per the manufacturer's curve. The contacts are signal type, not power — the limiting factor for current is the pin density in the shell, not the contact itself.
