Series 120 solenoid valves are ultra-miniature, magnetically latched solenoid valves featuring high-performance flow-switching characteristics. Weighing 300 mg, they require a momentary 1-ms pulse to switch the state (+5 VDC to open, -5 VDC to close) and are suitable for compact battery-powered pneumatic applications. The valves are 0.12 in. OD x 0.4 in. long, feature bi-stable performance, and promise quiet operation.
