FEATURES
1. High contact reliability over a long life has been made possible for low level loads.
Using a low level load (1 mV 10µA to 10 V 10 mA) 107 operations were achieved with a static contact resistance of Max. 100 mΩ (voltage drop of 20 mV, 1 mA, 1 kHz) and a dynamic contact resistance of Max. 1 Ω (Measurement delay 10 ms, voltage drop of 20 mV, 1 mA, 1 kHz).
2. High sensitibity of 50 mW
By using the highly efficient polar magnetic circuit "seesaw balance armature mechanism", a rated power consumption of 50 mW (for single side stable type) has been achieved.
3. Low thermal electromotive force
Reducing the heat from the coil enables a thermal electromotive force of 3 µV or less.
