A2KM1ASQ24VDC1.6R

Relay Automotive Overview

The A2KM1ASQ24VDC1.6R is a non-latching automotive relay from the CIT Relay and Switch A2K series, designed for high-current switching applications. It features a 24VDC coil with a resistance of 360 Ohms and a power consumption of 1.6W. The single-pole single-throw normally open (SPST-NO) contact arrangement supports a maximum switching current of 40A at 14VDC and a maximum switching voltage of 75VDC. Constructed with silver tin oxide (AgSnO) contacts, it offers an initial contact resistance of less than 30 milliohms and a maximum switching power of 630W.
