Overview

Automotive Relay 12v 40a is a relay used in automobile. This kind of relay has high switching load power, high impact and vibration resistance. The power supply in the automobile is mostly 12V, and the coil voltage is mostly designed as 12V. Due to battery power supply and unstable voltage; The environmental conditions are bad, and the suction voltage V ≤ 60% VH (rated working voltage); The coil overvoltage is allowed to reach 1.5vh. The coil power consumption is large, generally 1.6 ~ 2W, and the temperature rise is high. The environmental requirements are quite harsh: in the engine compartment, the ambient temperature range is - 40 ℃ ~ 125 ℃, and in other locations, the ambient temperature range is - 40 ℃ ~ 85 ℃; The relay used in the engine compartment shall be able to withstand the invasion of sand, dust, water, salt and oil; Vibration and impact are quite harsh.
