A2S1ASQ6VDC1.6D

Relay Automotive Overview

The A2S1ASQ6VDC1.6D is an automotive relay from the CIT Relay and Switch A2 series, designed for base mounting with quick-connect terminals. It features a single-pole single-throw normally open (SPST-NO) contact arrangement rated for up to 40A at 14VDC. The coil operates on a nominal 6VDC supply with a maximum voltage of 7.8VDC and a resistance of 1.6 Ohms. Key electrical parameters include a maximum switching voltage of 75VDC, a maximum switching power of 630W, and an initial contact resistance of less than 30 milliohms. The unit utilizes AgSnO2 contact material and is fully sealed.

Relay Automotive Feature Summary

• Fully sealed construction for environmental protection
• Compact design with lightweight characteristics
• Certified manufacturing under QS-9000 and ISO-9002 standards

Relay Automotive Applications

• Automotive electrical systems
• Lamp accessories control
• General automotive load switching

Relay Automotive Procurement Notes

Verify that the specific suffix 'D' in the part number corresponds to the intended diode configuration or variant, as datasheets may not explicitly detail suffix variations. Confirm the coil voltage matches the 6VDC requirement and ensure the application current does not exceed the 40A rating at 14VDC. Check for RoHS compliance status if required by project specifications.

Relay Automotive Selection Notes

Select this component when a 6VDC coil voltage is required for automotive applications. Ensure the load current stays within the 40A limit for SPST-NO contacts. Consider the base mounting style and quick-connect terminal type for PCB or harness integration. Verify that the 75VDC maximum switching voltage aligns with the circuit requirements.

Relay Automotive Part Context

This relay belongs to the CIT A2 series, which is characterized by large switching capacity and small size. The series is certified for automotive quality standards. The A2S1ASQ variant specifically denotes a sealed relay with quick-connect terminals and a standard contact arrangement, distinguishing it from other mounting or terminal options within the broader product line.
