25-Position DB-25 Receptacle with Board Locks
The TE Connectivity 2-747708-0 is a 25-position D-Sub receptacle from the AMPLIMITE HD-20 series, configured as a vertical through-hole solder mount with female sockets. The DB-25 shell layout (3, DB, B) is the standard density for serial and parallel port interfaces, industrial machine control, and test equipment I/O. The 6A per-contact rating at 125V covers signal-level and moderate power duty — think PLC I/O modules, data acquisition panels, or instrumentation backplanes where the 25-circuit count matches the bus width.
Board Lock and Mounting
The 4-40 threaded flange accepts standard D-Sub hardware (jackscrews or slide locks) for a vibration-resistant mate with the plug half.
Note that this part is RoHS non-compliant — verify your assembly's material restrictions before specifying. The steel shell with tin plating provides EMI shielding when mated to a grounded plug.
