Sanyou Electrical Appliances, Inc. Automotive Relay SARL-112DMD

The SARL-series automotive relay is a high-power relay designed for automotive control applications such as fuel pump, cooling fan, and headlight control. It features a 1-form C contact configuration, a 40A switching capacity at 14VDC, and a maximum switching voltage of 30VDC. The relay operates within a temperature range of -40 to +125°C, has an initial contact resistance of 100mΩ max, and a coil power rating of 2.0W with a 12VDC nominal voltage. It includes a diode for suppression and a bracket for mounting, with approximate dimensions defined by the standard outline. The relay meets functional vibration and shock resistance standards of 10-55Hz at 1.5mm amplitude and 20G min. respectively, and achieves 100,000 electrical operations at 600 ops/h. The contact material is AgSnO₂, and the unit weighs approximately 32.5g.
