AZ988-1AT-12DSEC1R

Relay Automotive Overview

The American Zettler AZ988-1AT-12DSEC1R is a Micro-ISO automotive relay designed for high-current switching applications. It features a single-pole, single-throw normally open (SPST-NO) contact arrangement rated at 30A with a maximum switching voltage of 27VDC. The unit utilizes a 12VDC coil with a resistance of 90 Ohms and a current draw of 133.3 mA. Constructed with silver tin oxide contacts, it offers robust performance within an operating temperature range of -40°C to 125°C. The relay is epoxy-sealed, ensuring protection against environmental factors while maintaining compliance with RoHS3 standards.

Relay Automotive Feature Summary

• Micro-ISO form factor with epoxy sealing for environmental protection
• High current capacity of 30A in a compact sub-miniature package
• Silver tin oxide contact material for durable switching performance

Relay Automotive Applications

• Automotive lighting circuits
• Trailer tow light control systems
• General vehicle accessory power distribution

Relay Automotive Procurement Notes

Verify the specific suffix configuration when ordering, as variations such as SEC1R or SEC3R may denote differences in terminal style or internal construction. Confirm that the required contact configuration matches the SPST-NO specification for your circuit design. Ensure compatibility with standard Micro-ISO sockets and verify that the 12VDC coil voltage aligns with the target vehicle's electrical system requirements before procurement.

Relay Automotive Selection Notes

Select this component when a compact, high-current solution is required for automotive environments. The 30A rating supports heavy loads compared to lower-amperage alternatives. The Micro-ISO footprint allows for direct replacement in existing harnesses designed for this series. Consider the 12VDC coil requirement and ensure the available space accommodates the physical dimensions of the sealed relay housing.

Relay Automotive Part Context

This part belongs to the AZ988 series of automotive relays manufactured by American Zettler. The series is characterized by its Micro-ISO size, which is smaller than standard ISO relays but larger than mini relays. The AZ988 line typically includes various contact configurations and coil voltages to suit different automotive needs, providing a versatile platform for OEM and aftermarket applications requiring reliable high-current switching.

Relay Automotive Replacement Considerations

Direct substitutes include other Micro-ISO relays with identical pinouts and ratings, such as the AZ988-1CT-12DC1R if a changeover contact is acceptable. Cross-reference with industry-standard Micro-ISO equivalents from other manufacturers, ensuring the 30A rating and 12VDC coil specifications match exactly.
