• SPST-NO contact configuration for single circuit control
• Internal blowout magnets enhance arc suppression capabilities
• Capable of switching voltages up to 110VDC

Relay Automotive Applications

• Automotive lamp control systems
• DC motor control circuits
• General automotive accessory power distribution
• High-current switching in vehicle electrical architectures

Relay Automotive Procurement Notes

Verify the specific suffix 'R' indicates the inclusion of a resistor or suppressor component if required by the circuit design. Confirm that the 48VDC coil voltage matches the vehicle's electrical system specifications. Ensure the socket type aligns with the quick connect termination style specified in the official datasheet to guarantee proper mechanical and electrical engagement.

Relay Automotive Selection Notes

Select this model when a 48VDC control signal is available and a normally open single-pole configuration is required. The 40A rating supports heavy loads such as lighting or motors. Consider the socketable form factor for ease of maintenance and replacement in automotive assemblies where chassis mounting is not preferred over plug-in installation.

Relay Automotive Part Context

This part belongs to the CIT automotive relay family, characterized by compact dimensions and robust switching capacity. It is engineered for durability in harsh automotive environments, meeting ISO quality certifications. The series offers various coil voltages and contact arrangements to suit diverse vehicle electrical requirements.

Relay Automotive Replacement Considerations

Direct substitutes include the A2K1ASQ48VDC1.6, which shares identical electrical characteristics but may differ in packaging or internal components. Verify pin compatibility and coil resistance before substitution to ensure functional equivalence in the target application.
