EXSYS EX-49025 D-SUB 25-pin Male to 27-pin Screw Terminal Block Adapter, Green/Silver

When you need to connect a legacy 25-pin D-SUB device to individual wires for industrial control, data acquisition, or custom serial interfaces, this adapter eliminates soldering and provides a reliable screw terminal breakout. The EX-49025 converts each of the 25 D-SUB pins to a corresponding screw terminal, plus two additional ground terminals, in a compact green and silver housing.

Who is it for

Engineers, technicians, and system integrators working with RS-232 or parallel interfaces who need a quick, secure way to terminate field wiring without custom cables.
