A2S1ASQ48VDC1.6R

Relay Automotive Overview

The A2S1ASQ48VDC1.6R is a sealed SPST-NO automotive relay from the CIT A2 series, designed for high-current switching applications. It features a 48VDC coil with a resistance of 90 Ohms and consumes 1.6W of power. The contact arrangement supports up to 40A at 75VDC maximum switching voltage. Constructed with AgSnO2 contacts, it offers low initial contact resistance under 30 milliohms. The unit utilizes quick connect termination (0.250 inch) and includes a metal bracket and shroud for secure mounting.

Relay Automotive Feature Summary

• Sealed construction with metal bracket and shroud for environmental protection
• High switching capacity supporting up to 40A current load
• Quick connect termination compatible with standard automotive harnesses

Relay Automotive Applications

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

Relay Automotive Procurement Notes

Verify that the specific part number matches the required 48VDC coil voltage and SPST-NO contact configuration. Confirm compatibility with existing mounting brackets due to the integrated metal shroud design. Ensure the quick connect pin dimensions align with the target PCB or wiring harness connectors before finalizing procurement orders.

Relay Automotive Selection Notes

Select this component when a 48VDC control signal is available and a single normally open contact path is required. The 40A rating makes it suitable for high-power loads compared to lower-rated relays. Consider the physical dimensions and bracket requirements if space constraints exist within the vehicle's electrical compartment.

Relay Automotive Part Context

This relay belongs to the CIT A2 series, which is certified under QS-9000 and ISO-9002 standards. The series is characterized by small size, light weight, and large switching capacity. It is widely used in automotive environments where reliability and durability are critical for electrical component performance.

Relay Automotive Replacement Considerations

Direct substitutes include other A2 series variants with identical coil voltage and contact form, such as A2S1ASQ12VDC1.6R for different voltage requirements. Verify that any replacement maintains the same 40A rating and sealed construction specifications.
