A2F1ASQ24VDC1.6D

Relay Automotive Overview

The A2F1ASQ24VDC1.6D is an automotive relay manufactured by CIT Relay and Switch, designed for chassis mounting applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration, providing reliable switching for high-current circuits. The unit operates with a 24VDC coil voltage and draws a coil current of 66.7 mA. It utilizes a non-latching coil type to maintain its state only while energized. The relay supports a maximum contact rating of 40A, making it suitable for demanding automotive electrical systems. The device is engineered to function within an operating temperature range of -40°C to 125°C, ensuring durability in harsh environmental conditions typical of vehicle installations.

Relay Automotive Feature Summary

• SPST-NO contact form for standard switching control
• High current capacity up to 40A for heavy loads
• Chassis mount design for secure installation
• Wide operating temperature range for automotive use

Relay Automotive Applications

• Automotive lighting circuits
• Motor control systems
• Heater and fan activation
• Auxiliary power distribution

Relay Automotive Procurement Notes

Verify the specific ordering suffix matches the required coil voltage and contact configuration. Confirm that the chassis mount style aligns with the available mounting hardware in the target assembly. Ensure the 24VDC coil specification is compatible with the vehicle's electrical system to prevent damage or improper operation during procurement.

Relay Automotive Selection Notes

Select this component when a robust, high-current switching solution is required for automotive environments. The SPST-NO configuration is ideal for simple on/off control applications. Consider the 40A rating to ensure the relay can handle the peak load of the connected equipment without overheating or contact degradation over time.

Relay Automotive Part Context

This part belongs to the CIT automotive relay series, which focuses on durable switching components for vehicle electronics. The A2F1ASQ24VDC1.6D variant specifically addresses the need for 24VDC actuation in commercial and industrial vehicles. It complements other relays in the lineup by offering a balance of high current handling and compact physical dimensions for space-constrained chassis installations.

Relay Automotive Replacement Considerations

Direct substitutes may include models with identical SPST-NO contacts and 24VDC coils from the same manufacturer line. Verify pinout compatibility and mounting hole spacing before replacing. Cross-reference with A2F1ASQ24VDC1.6R if reel packaging is preferred over individual units.
