General Info

The W40 or W20 is a low cost Pin-Screw terminal adaptor.
W40 converts standard 0.1 in lead spacing 20×2 pin headers to 40 screw terminals for easy field wiring. W20 has 20 screw terminals and 20 pins. The W40P has a 20×2 pin-header for using a flat ribbon cable.

The W40S has a 20×2 socket for mounting on top of pin-headers.
