A11ASQ48VDC1.2

Relay Automotive Overview

The A11ASQ48VDC1.2 is an automotive electromechanical relay manufactured by CIT Relay and Switch, designed for high-current switching applications. It features a single-pole single-throw normally open (SPST-NO) contact configuration capable of handling up to 30A at a maximum switching voltage of 75VDC. The coil operates on 48VDC with a non-latching mechanism, drawing 25mA of current. Constructed with silver tin oxide contacts, the unit supports both PCB pin and quick connect mounting styles. It is fully sealed, RoHS3 compliant, and rated for operation within a temperature range of -40°C to 125°C.

Relay Automotive Feature Summary

• Fully sealed construction protects internal components from environmental factors
• Dual mounting flexibility supports both PCB pins and quick connect terminals
• High current capacity suitable for demanding automotive electrical loads

Relay Automotive Applications

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

Relay Automotive Procurement Notes

Verify that the specific variant matches the required coil voltage and contact form factor for your design. Confirm whether the quick connect or PCB pin terminal style is needed, as these affect board layout and wiring harness compatibility. Ensure the operating environment stays within the specified thermal limits and that the sealing rating meets the application's exposure requirements.

Relay Automotive Selection Notes

Select this component when a 48VDC coil drive is available and a 30A SPST-NO switch is required. Consider the physical mounting constraints to determine if the PCB or quick connect interface fits the assembly. Verify that the 75VDC maximum switching voltage aligns with the load circuit specifications and that the sealed package meets the necessary protection standards.

Relay Automotive Part Context

This part belongs to the A11 series of automotive relays from CIT Relay and Switch. The series is characterized by compact dimensions and lightweight design, making it suitable for space-constrained vehicle applications. The A11 series offers various coil voltages and contact configurations to support diverse automotive electronic needs.

Relay Automotive Replacement Considerations

Cross-reference with other A11 series variants such as A11ASQ12VDC1.2 or A11ASQ24VDC1.2 if different coil voltages are required. Ensure any substitute maintains the same 30A current rating and SPST-NO contact form to preserve circuit functionality.
