1 / 5 page SX 120 SX-RELAYS HIGH SENSITIVITY RELAY WITH GUARANTEED LOW LEVEL SWITCHING CAPACITY 7.4 .291 15.0 .591 8.2 .323 mm inch 7.4 .291 15.0 .591 Max. 10.0 .394 FEATURES 1. High contact reliability over a long life has been made possible for low level loads. Using a low level load (1 mV 10 µA to 10 V 10 mA) 107 operations were achieved with a static contact resistance of Max. 100 m Ω (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 magnet- ic 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. SPECIFICATIONS Contact Notes: **1 This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the ac- tual load. **2 For single side stable only. Characteristics Remarks: * Specifications will vary with foreign standards certification ratings. *1 By nominal switching capacity: No. of operations: 107 *2 Measurement at same location as "Initial breakdown voltage" section. *3 Detection current: 10mA. *4 Nominal voltage applied to the coil, excluding contact bounce time. *5 By resistive method, nominal voltage applied to the coil; contact carrying current: 10mA. *6 Half-wave pulse of sine wave: 6 ms; detection time: 10 µs. *7 Half-wave pulse of sine wave: 6 ms. *8 Detection time: 10 µs. *9 Refer to 5.
