A3M1ASQ24VDC2D

Relay Automotive Overview

The A3M1ASQ24VDC2D is a sealed automotive relay manufactured by CIT Relay and Switch. It features an SPST-NO (Form A) contact arrangement rated for up to 80A at 75VDC. The coil operates on 24VDC with a resistance of 320 Ohms and draws 75mA. Designed for base mounting, it utilizes quick-connect terminals available in multiple sizes. The unit functions within a temperature range of -40°C to 125°C, incorporating a built-in diode for protection.

Relay Automotive Feature Summary

• Sealed construction designed for harsh automotive environments
• High switching capacity supporting heavy-duty loads up to 80A
• Integrated suppression diode for coil protection
• Compatible with socketable base mounting configurations

Relay Automotive Applications

• Automotive lighting circuits
• Heavy-duty accessory power distribution
• Industrial control systems requiring high current switching

Relay Automotive Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct coil voltage and terminal configuration. Confirm that the required base socket is sourced separately if not included in the packaging. Check RoHS compliance status for specific regional regulatory requirements before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a single-pole normally-open circuit requires high current handling capabilities in automotive or industrial applications. Ensure the system voltage aligns with the 24VDC coil specification. Verify that the physical dimensions and quick-connect terminal types match the existing PCB or wiring harness layout constraints.

Relay Automotive Part Context

This model belongs to the A3M series of automotive relays from CIT Relay and Switch. The series is characterized by robust sealing and high current ratings suitable for demanding vehicle electrical architectures. The A3M1ASQ24VDC2D specifically denotes the 24VDC coil variant with standard quick-connect terminals.

Relay Automotive Replacement Considerations

Cross-reference part numbers such as A3M1ASQ12VDC2D for identical mechanical and contact specifications but different coil voltage requirements. Ensure substitute components maintain the same SPST-NO contact form and base-mounting compatibility.
