A11CSQ48VDC1.2D

Relay Automotive Overview

The A11CSQ48VDC1.2D is an automotive relay manufactured by CIT Relay and Switch, designed for high-performance electronics applications. It features a non-latching coil type with a 48VDC coil voltage and 25mA coil current. The contact configuration is SPDT (1 Form C), supporting a maximum switching voltage of 75VDC and a current rating of 30A. Key electrical parameters include a must-operate voltage of 33.6VDC. The component utilizes plug-in termination with quick connect options and is socketable for panel mounting.

Relay Automotive Feature Summary

• High-current capacity suitable for demanding automotive electronic loads
• Socketable design enabling easy installation and replacement in vehicle systems
• Non-latching operation ensures standard single-side stable functionality

Relay Automotive Applications

• Automotive electronics control circuits
• Vehicle power distribution systems
• Industrial equipment requiring 48VDC actuation

Relay Automotive Procurement Notes

Verify the specific quick connect terminal size compatibility with existing harnesses before procurement. Confirm that the 48VDC coil voltage aligns with the target system's power supply architecture. Ensure the selected socket matches the physical footprint and pin configuration to guarantee proper mechanical engagement and electrical continuity during assembly.

Relay Automotive Selection Notes

Select this model when a 30A SPDT switch is required for 48VDC automotive environments. Consider the plug-in form factor for maintenance accessibility. Evaluate thermal management needs given the high current rating. Compare against lower voltage variants if system architecture differs. Ensure the non-latching characteristic meets the control logic requirements of the application.

Relay Automotive Part Context

This component belongs to the A1 series of automotive relays from CIT Relay and Switch. The series is characterized by robust construction for vehicle use. Variants within the series differ primarily in coil voltage and contact configuration. This specific part represents a high-current solution for 48-volt systems, distinct from lower voltage or lower amperage counterparts in the same product family.

Relay Automotive Replacement Considerations

Compatible substitutes include other CIT Automotive Relays with identical 48VDC coil voltage, 30A SPDT contacts, and matching quick-connect terminal sizes. Verify mechanical dimensions and socket compatibility to ensure direct interchangeability without modifying the PCB or panel layout.
