Make wiring in an industrial cabinet easy with this DB9 female to terminal block adapter. Connections can be made quickly without any special tools. Install it once - then you can replace components error-free with a simple unplug/re-plug, rather than tediously unfastening and refastening numerous wires individually to terminal blocks. Its compact size and DIN rail mountability is perfect for wiring areas with limited space. _x000D_
