A11ASQ12VDC1.2

Relay Automotive Overview

The A11ASQ12VDC1.2 is an automotive relay from the CIT Relay and Switch A1 series, designed for socketable installation in vehicle electrical systems. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a maximum switching current of 30A at 14VDC. The coil operates on 12VDC with a non-latching mechanism, drawing 100mA. Key specifications include a switching capacity up to 30A, a maximum switching voltage of 75VDC, and a contact resistance of less than 30 milliohms initially. The unit utilizes silver tin oxide (AgSnO2) contact material and supports quick connect mounting options.

Relay Automotive Feature Summary

• Sealed construction suitable for automotive environments
• Socketable design for easy replacement and maintenance
• High switching capacity up to 30A for heavy loads
• Quick connect terminals for simplified wiring

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power distribution
• Industrial control panels requiring sealed relays
• Lamp accessories and signaling systems

Relay Automotive Procurement Notes

Verify the specific suffix designation when ordering, as variants such as A11ASQ12VDC1.2D include integrated diodes while standard versions do not. Confirm that the application requires a socketable form factor rather than direct PCB or base mounting. Ensure the operating environment temperature range aligns with the component's rated limits. Cross-reference the contact rating against peak load requirements to prevent premature failure. Check for RoHS compliance status if environmental regulations apply to the end product.

Relay Automotive Selection Notes

Select this model when a 12VDC coil voltage and SPST-NO configuration are required for automotive or industrial applications. The 30A rating distinguishes it from lower-capacity family members like the J098. Consider the A11ASQ12VDC1.2D variant if flyback protection is needed without external components. Evaluate the sealed nature against unsealed alternatives for durability in harsh conditions. Ensure the quick connect interface matches existing harness connectors.

Relay Automotive Part Context

This component belongs to the CIT A1 series of automotive relays, characterized by compact dimensions and robust sealing. It complements higher-capacity models like the A3M1BCP series and distinct variants within the same family. The A11ASQ12VDC1.2 serves as a standard solution for moderate current switching tasks where reliability and ease of installation via sockets are prioritized over direct board mounting.

Relay Automotive Replacement Considerations

Direct substitutes within the CIT lineup include the A11ASQ12VDC1.2R for reel packaging or the A11ASQ12VDC1.2D if a built-in suppression diode is necessary. External cross-manufacturer replacements must match the 12VDC coil, 30A contact rating, and SPST-NO form factor. Verify physical footprint compatibility for socket-based installations.
