A2M1ASQ48VDC1.6D

Relay Automotive Overview

The A2M1ASQ48VDC1.6D is an automotive electromechanical relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a single-pole single-throw normally open (SPST-NO) contact arrangement capable of handling up to 40A at 14VDC. The coil operates on a 48VDC supply with a rated power consumption of 1.6W. Key electrical specifications include a maximum switching voltage of 75VDC and a minimum initial contact resistance of less than 30 milliohms. The unit utilizes silver tin oxide (AgSnO2) contact material and supports both PCB pin and quick connect mounting options.

Relay Automotive Feature Summary

• High switching capacity supporting up to 40A loads
• Compact physical design with lightweight construction
• Versatile mounting compatibility including PCB pins and quick connects

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• General purpose high-current switching

Relay Automotive Procurement Notes

Verify the specific ordering suffix to ensure the correct coil voltage and contact configuration match the system requirements. Confirm that the 48VDC coil rating aligns with the available control circuit voltage. Check for RoHS compliance status if environmental regulations apply to the assembly. Ensure the quick connect terminal dimensions are compatible with existing harness connectors or PCB footprints before finalizing procurement.

Relay Automotive Selection Notes

Select this component when a 48VDC control signal is required for activating a load up to 40A. The SPST-NO configuration is suitable for simple on/off control scenarios. Consider the thermal management capabilities as the relay dissipates heat during operation. Verify that the operating temperature range of -40°C to 125°C meets the environmental conditions of the intended installation site.

Relay Automotive Part Context

This relay belongs to the A2 series from CIT Relay and Switch, which focuses on automotive-grade components. The series is characterized by robust construction and certification standards such as QS-9000 and ISO-9002. These relays are engineered to withstand the harsh environments typical of vehicle applications, providing reliable performance over extended operational lifespans.

Relay Automotive Replacement Considerations

Cross-reference part numbers within the same A2 series family for alternative coil voltages or contact arrangements. Ensure any substitute maintains the 48VDC coil requirement and 40A current rating. Verify mechanical footprint compatibility if replacing in an existing assembly.
