25-Position Right-Angle D-Sub with Board Locks
The TE Connectivity 3-106507-2 is a 25-position D-Sub receptacle from the AMPLIMITE HD-20 series, configured as a right-angle PCB-mount with integrated board locks. The 25-position shell layout (DB-25) is the standard-density format for parallel-port, serial, and industrial I/O interfaces. The steel shell with tin plating provides EMI shielding when mated with a conductive backshell.
Termination is through-hole solder to the PCB. The backset spacing of 0.406" (10.30 mm) sets the distance from the PCB surface to the mounting flange, which determines the panel cutout depth and the screwlock reach. The flange features female screwlocks on the mating side, threaded 4-40 UNC. The shell size is 3 (DB, B), which is the standard DB-25 footprint; the panel cutout and hole pattern match every other DB-25 connector.
