Product features and benefits Function: M12 4pin maletofemale aviation connector with an integrated trigger line for automatic reversingcamera activation. The trigger line connects to the reversinglight power supply so the camera powers up automatically when the vehicle is shifted into reverse. Secure connection: Female connector includes a locking screw to prevent accidental disconnection and ensure a reliable electrical and mechanical connection in mobile or vibrationprone environments. Simple installation: Plugandplay wiring using standard M124PIN pinout reduces installation time and minimizes wiring errors. Reliability: M12 aviationstyle construction provides a robust, purposebuilt interface for vehicle camera and accessory systems. Key attributes Connector type: M12 4pin (male to female). Trigger function: Dedicated trigger line on the twoend plug for reverselight power sensing and automatic camera start. Locking: Female connector equipped with a locking screw for stable attachment. Compatibility: Designed for reversingcamera systems and other 4pin devices that accept M124PIN connections and require a reverse trigger input. Size reference: M12 connector family (metric 12mm mounting/thread standard). Why you need this product Automates camera activation: Eliminates the need for manual camera on/off switching by using the vehicle's reverselight circuit to trigger the camera. Improves safety and convenience: Ensures the reversing camera is active only when needed, reducing driver distraction and preserving camera lifespan. Creates a secure, vibrationresistant connection: Locking female connector reduces risk of intermittent signal loss in automotive environments. Standardized interface: M124PIN format keeps wiring consistent with many commercial vehicle camera systems, simplifying maintenance and replacements. Typical applications and use scenarios Passenger cars and light trucks: Connect a reversing camera to the vehicle's reverselight circuit so the monitor and camera turn on automatically when shifting into reverse. Commercial fleets and delivery vehicles: Provide a durable, vibrationresistant camera connection for backup systems on vans, box trucks, and service vehicles. Aftermarket camera installations: Use as the interface cable between an M12equipped reverse camera and the vehicle harness, with the trigger line wired to the reversing light for automatic activation. What to check before Ensure your camera and display accept M12 4pin connectors and that the system supports a trigger input wired to the reversing light. Confirm the vehicle reversinglight power connection is available where the trigger line will be installed.
