Automotive Relay

Relay is a kind of automatic control device whose output will change abruptly when input quantity (electricity, magnetism, sound, light and heat) reaches a certain value. And the car relay is the relay used in the car, this kind of relay switches the load power, anti-shock and high vibration resistance. The power in the car is more 12V, the voltage of the coil is mostly designed to 12V. Because it is battery-powered, the voltage is unstable; , The suction voltage V ≤ 60% VH (fixed working voltage); coil over-voltage allows up to 1.5VH Coil larger power consumption, typically 1.6 ~ 2W, high temperature rise Environmental requirements are quite demanding :. In the engine compartment, the ambient temperature is -40 ℃ ~ 125 ℃ and the ambient temperature is -40 ℃ ~ 85 ℃. The relays used in the engine compartment should withstand the dust, water, salt and oil. Vibration, shock quite demanding.

Automotive relays by the magnetic circuit system, contact system and rehabilitation agencies. Magnetic circuit system from the core, yoke, armature, coils and other components. Contact system consists of static reed, moving reed, contact base and other components. Recovery mechanism by the reed or tension spring composition.
