OEX ACX1980BL Micro Relay 12V Normally Open 20A - Resistor Protected, Sealed

OEX ACX1980BL 12V 20A Normally Open Micro Relay Japanese Configuration 4 Pin Resistor Spike Protection IP67 Single Unit

The OEX ACX1980BL is a 12V, 20A normally open micro relay with resistor spike protection, supplied as a single unit. Smaller than the standard mini relay format, the micro relay suits installations where mounting space is limited or where the vehicle's factory relay socket uses the micro relay footprint common in many Japanese-configuration vehicles. Four-terminal layout with coil connections (85 and 86) and normally open switching contacts (30 and 87) no normally closed contact. Silver tin oxide contacts and IP67 sealed housing. Covered by a one year warranty.

Product overview

The ACX1980BL is a micro relay physically smaller than the standard mini relay (ACX1940RBL series) and using a different terminal footprint. Micro relays are commonly found in Japanese-market vehicles and are not interchangeable with standard ISO mini relay sockets. The Japanese configuration footprint matches the relay socket used in many vehicles manufactured by Japanese brands. Always confirm the relay format required for your vehicle or application before purchasing using a micro relay in a mini relay socket or vice versa will not produce a secure connection.

At 20A the ACX1980BL covers accessory and auxiliary circuit switching in applications where the smaller footprint is required. The resistor spike protection suppresses the voltage spike generated when the relay coil is de-energised, protecting ECU and control module outputs in the triggering circuit. The IP67 sealed housing provides full protection against dust and temporary water immersion.

Features and benefits

Micro relay format: Physically smaller than the standard mini relay, suited to tight installation spaces and Japanese vehicle configurations where the micro relay footprint is required.

Japanese configuration: Terminal layout and footprint matches the relay socket used in many Japanese-brand vehicles. Not interchangeable with standard ISO mini relay sockets.

20A rating: Suited to accessory and auxiliary circuit switching up to 20A in applications requiring the micro relay format.

Normally open contact: Circuit is open at rest and closes when the relay coil is energised.

4 pin configuration: Coil connections (85 and 86) and normally open switching contacts (30 and 87). No normally closed contact (87a).

Resistor spike protection: Suppresses the voltage spike generated when the relay coil is de-energised, protecting ECU and control module outputs.

IP67 sealed housing: Fully protected against dust and temporary water immersion, suited to underbonnet and exposed mounting positions.

Silver tin oxide contacts: Reliable switching performance with excellent contact life.

Single unit: For individual installations or replacements.

One year warranty: Covered by a one year OEX warranty.

Frequently asked questions

What is a micro relay and how does it differ from a mini relay? A micro relay is physically smaller than a standard mini relay and uses a different terminal footprint. Micro relays are commonly found in Japanese-market vehicles and are not interchangeable with mini relay sockets. Always confirm the relay format required for your vehicle or application before purchasing.

What does "Japanese configuration" mean? Japanese configuration refers to the terminal layout and footprint used in many vehicles manufactured by Japanese brands. This differs from the standard ISO mini relay footprint used in European and most aftermarket applications. Confirm your vehicle's relay socket configuration before purchasing.

Why does this relay have 4 terminals instead of 5? As a normally open relay there is no normally closed contact (87a), resulting in 4 terminals: 85 (coil negative), 86 (coil positive), 30 (common) and 87 (normally open). If a change over relay with both NO and NC contacts is required, a 5-terminal relay is needed.

What does resistor spike protection do? When a relay coil is de-energised it generates a voltage spike that can damage sensitive electronics. A resistor across the coil terminals suppresses this spike, protecting ECU and control module outputs used to trigger the relay.

Is this relay suitable for underbonnet use? Yes. The IP67 sealed housing provides full protection against dust and temporary water immersion, making it suitable for underbonnet and exposed mounting positions.
