This Pneumatic Solenoid Driver Cable is this same driver cable that is included in the Pneumatic Kits. On one end of the Driver Cable is the standard 3 wire PWM Connector which connects to a VEX Microcontroller Digital Output. On the other end is the 2 wire Pneumatic Connector which mates directly to the Pneumatic Solenoid. This cable takes the digital On\\Off signal and controls the 5V power applied to a pneumatic solenoid. The Pneumatic Solenoid Driver Cable is rated for about 3/4 Amp and is sold as a 2 pack.
