A11ASQ24VDC1.2

Relay Automotive Overview

The A11ASQ24VDC1.2 is an automotive SPST-NO relay manufactured by CIT Relay and Switch, designed for 24VDC coil operation with a non-latching configuration. It features a maximum switching current of 25A and a maximum switching voltage of 75VDC, supporting up to 350W of power. The unit utilizes quick connect terminals (0.187 inch) for socketable installation. Key electrical parameters include a coil resistance of 480 Ohms, a coil current of 50 mA, and a contact resistance of 50mΩ. Mechanical timing specifications specify an operate time of 10ms and a release time of 7ms.

Relay Automotive Feature Summary

• SPST-NO contact form provides single pole switching capability for circuit control applications
• Non-latching coil design ensures immediate de-energization upon signal loss
• Socketable construction with quick connect terminals facilitates standardized mounting

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power distribution
• Industrial control panel switching

Relay Automotive Procurement Notes

Verify the specific terminal pitch matches the target socket interface before integration. Confirm that the 24VDC coil voltage aligns with the system's available supply rails. Ensure the 25A continuous current rating exceeds the load requirements to prevent thermal degradation. Check for RoHS compliance status if environmental regulations apply to the assembly.

Relay Automotive Selection Notes

Select this component when a 24VDC automotive-grade relay with SPST-NO functionality is required. The 25A capacity suits moderate load applications such as lamps or small motors. Consider the 75VDC voltage limit for compatibility with standard vehicle electrical systems. The non-latching nature makes it suitable for direct-switching tasks without memory retention.

Relay Automotive Part Context

This model belongs to the CIT Relay and Switch automotive series, characterized by robust construction for vehicular environments. The A11ASQ designation indicates a specific form factor optimized for quick-connect interfaces. It serves as a standard electromechanical solution for isolating control signals from high-current loads in transportation equipment.

Relay Automotive Replacement Considerations

Direct substitutes must match the 24VDC coil voltage, SPST-NO contact form, and 25A current rating. Verify terminal type compatibility, specifically the 0.187-inch quick connect style. Cross-reference mechanical dimensions to ensure fit within existing socket assemblies.
