A11ASQ12VDC1.2R

Relay Automotive Overview

The A11ASQ12VDC1.2R is an automotive relay manufactured by CIT Relay and Switch, designed for high-current switching applications in vehicle electrical systems. It features a single-pole single-throw normally open (SPST-NO) contact configuration with a rated current capacity of 30A at 14VDC. The coil operates on 12VDC with a power consumption of 1.2W and a resistance of 120 Ohms. Key performance metrics include an operate time of 10 ms and a release time of 7 ms. The unit utilizes quick-connect terminals measuring 0.250 inches (6.3mm) for installation and is sealed to protect against environmental factors.

Relay Automotive Feature Summary

• Sealed construction provides protection against environmental contaminants
• Quick-connect terminal style facilitates rapid board or harness integration
• High switching capacity supports demanding automotive electrical loads

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power distribution
• General purpose automotive switching

Relay Automotive Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required mounting styles and terminal configurations. Confirm that the 12VDC coil voltage aligns with the target system's nominal operating range. Check datasheet specifications for thermal derating requirements if operating near the maximum current rating. Ensure the SPST-NO contact form matches the intended circuit logic. Validate environmental ratings against the installation location conditions.

Relay Automotive Selection Notes

Select this component when a 30A switching capacity is required for 12VDC automotive applications. The SPST-NO configuration is suitable for simple on/off control of loads such as lights or motors. Consider the 10 ms operate time for applications requiring moderate response speeds. The sealed design makes it appropriate for under-hood or exposed mounting positions where moisture and dust resistance are necessary.

Relay Automotive Part Context

This part belongs to the A Series relays from CIT Relay and Switch, which are engineered for automotive use. The A11ASQ series offers various coil voltages and contact arrangements to suit different vehicle electrical architectures. These relays are certified under QS-9000 and ISO-9002 standards, indicating adherence to quality management systems specific to the automotive industry supply chain.

Relay Automotive Replacement Considerations

Direct replacements must match the 12VDC coil voltage, 30A current rating, and SPST-NO contact form. Verify that substitute components support quick-connect terminals with 0.250-inch spacing. Ensure the replacement maintains equivalent sealing and environmental protection levels for the intended application environment.
