EXSYS EX-49110 DB9 Male to 9-Pin Screw Terminal Block Adapter with Push Button

In industrial control panels and prototyping labs, technicians often need a reliable way to break out a DB9 serial connection to individual wires. The EXSYS EX-49110 adapter provides a direct 1:1 mapping from a 9-pin D-Sub male connector to a 9-pin screw terminal block, simplifying wiring for RS232, RS485, or RS422 signals. An integrated push button offers convenient signal testing or reset functionality without additional tools.
