HIGH SENSIBILITY RELAY WITH GUARANTEED LOW LEVEL SWITCHING CAPACITY SX RELAYS (ASX) 1. FEATURES 1. High contact reliability over a long life has been made possible for low level loads. Using a low level load (1 mv 1µA to 1 V 1 ma) 1 7 operations were achieved with a static contact resistance of 1 mω (voltage drop of 2 mv, 1 ma, 1 khz) and a dynamic contact resistance of 1 Ω (Measurement delay 1 ms, voltage drop of 2 mv, 1 ma, 1 khz). 2. High sensibility of 5 By using the highly efficient polar magnetic circuit seesaw balance armature mechanism, a rated power consumption of 5 (for single side stable type) has been achieved. 3. Low thermal electromotive force Reducing the heat from the enables a thermal electromotive force of 3 µv or less.
