LEE SERIES 120 SOLENOID VALVE
The world's smallest solenoid valve
The Lee Series 120 Solenoid Valve sets a new standard in reducing space, weight and power consumption. This ultra-miniature, magnetically latched solenoid valve weighs just 300 mg and features high performance flow switching characteristics. The valve requires only a momentary 1 ms pulse to switch the state (+5 VDC to open, -5 VDC to close) and is ideal for compact battery powered pneumatic applications such as air piloting, lab automation (lab-on-a-chip) and other power-sensitive OEM flow switching devices. The Series 120 Solenoid Valve features reliable bi-stable performance, quiet operation and is currently available under Part # LFLX0510200B.
