A11CSQ48VDC1.2R

Relay Automotive Overview

The A11CSQ48VDC1.2R is an automotive relay manufactured by CIT Relay and Switch, featuring a 48VDC coil voltage and SPDT (1 Form C) contact configuration. It supports a maximum current of 30 Amps with a coil power consumption of 1.2W. The device utilizes a non-latching single-side operating function and includes a built-in diode (1N4005) for protection. Designed for quick connect mounting, this sealed relay ensures reliable performance in automotive environments.

Relay Automotive Feature Summary

• SPDT contact configuration provides versatile switching capabilities for single circuit control applications.
• Integrated protection diode safeguards the coil circuit against voltage spikes during operation.
• Sealed construction protects internal components from environmental contaminants and moisture.

Relay Automotive Applications

• Automotive lighting circuits
• Vehicle accessory power management
• Industrial control panels requiring 48VDC actuation

Relay Automotive Procurement Notes

Verify that the specific suffix 'R' corresponds to the required reel packaging or variant specifications if applicable. Confirm compatibility with existing PCB footprints or socket types. Ensure the 48VDC coil rating matches the system's control voltage precisely to avoid operational failure. Cross-reference the part number with official CIT Relay and Switch documentation to confirm the inclusion of the specified internal diode.

Relay Automotive Selection Notes

Select this component when a 48VDC coil voltage is required for automotive or industrial applications. The 30A contact rating suits high-current loads such as motors or heaters. The SPDT configuration allows for normally open and normally closed switching within a single unit. Consider the sealed design for harsh environments where dust or moisture resistance is critical for long-term reliability.

Relay Automotive Part Context

This relay belongs to the A11 series of automotive relays from CIT Relay and Switch. The series is characterized by robust construction suitable for vehicle electrical systems. Variants within the series differ primarily by coil voltage and contact configuration. The A11CSQ48VDC1.2R represents a specific configuration optimized for 48VDC systems with sealed contacts.

Relay Automotive Replacement Considerations

Compatible substitutes include the A11CSQ48VDC1.2D and A11CSQ48VDC1.2 models from CIT Relay and Switch. These variants share identical electrical specifications and form factors. Verify that any replacement maintains the same SPDT contact configuration and 48VDC coil rating. Ensure the physical mounting style remains compatible with the existing assembly.
