A2M1ASP24VDC1.6R

Relay Automotive Overview

The A2M1ASP24VDC1.6R is an ISO-sized automotive relay manufactured by CIT Relay and Switch, designed for high-capacity switching applications. It features a single-pole single-throw normally open (SPST-NO) contact arrangement capable of handling up to 40A at 14VDC. The unit utilizes a 24VDC coil with a rated power consumption of 1.6W and a resistance of 90 ohms. Constructed with AgSnO2 contacts, it offers low initial contact resistance below 30 milliohms. The relay supports both PCB pin and quick connect mounting options, ensuring versatility in installation environments.

Relay Automotive Feature Summary

• High switching capacity supporting up to 40A loads
• Compact design with lightweight construction for efficient space utilization
• Versatile mounting options including PCB pins and quick connect terminals

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• DC motor control circuits

Relay Automotive Procurement Notes

Verify the specific coil voltage rating of 24VDC and the SPST-NO configuration against system requirements before integration. Confirm that the 1.6W coil power consumption aligns with available driver circuit capabilities. Ensure the quick connect termination style matches existing harness connectors or adapt accordingly for PCB pin implementations.

Relay Automotive Selection Notes

Select this component when a robust ISO-sized relay is required for high-current DC applications. The 40A rating makes it suitable for heavy loads compared to standard mini relays. Consider the 24VDC coil requirement to ensure compatibility with vehicle or equipment electrical architectures. The AgSnO2 contact material provides durability for frequent switching operations in demanding environments.

Relay Automotive Part Context

This part belongs to the CIT A2 series of ISO automotive relays, which are standardized for use in various transportation and industrial sectors. The series is known for its reliability and compact form factor, allowing for dense circuit board layouts or direct panel mounting. It complements other variants in the lineup that offer different contact arrangements and coil voltages.

Relay Automotive Replacement Considerations

Compatible substitutes include the A2M1ASP24VDC1.6 without the R suffix if resistor inclusion is not critical. Other ISO-sized relays from different manufacturers may serve as functional equivalents provided they match the 24VDC coil, 40A current rating, and SPST-NO configuration.
