The sensor detects the metal mass of an approaching vehicle in motion and signals the gate opener to activate, providing a seamless exit experience. It features an adjustable sensitivity range to reduce false triggers from passing traffic or nearby metal objects. Intended for residential gate installations, the FM138 is installed by property owners or low-voltage technicians working with Mighty Mule gate opener systems.\u003c\/p\u003e\u003cp\u003eThe FM138 is suited for single-gate residential applications where automatic exit detection is needed. It works in conjunction with compatible Mighty Mule accessories and is designed for direct burial installation. The package includes 50 feet of direct burial cable, giving installers sufficient run length for most standard driveway setups without needing additional wire. The adjustable sensitivity setting allows the installer to fine-tune detection range based on driveway width and traffic patterns.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMagnetic sensor detects metal mass in motion for reliable vehicle detection\u003c\/li\u003e\n\u003cli\u003eAdjustable sensitivity range to minimize false activations\u003c\/li\u003e\n\u003cli\u003eIncludes 50 feet of direct burial cable for underground wiring runs\u003c\/li\u003e\n\u003cli\u003eWorks with all Mighty Mule accessories for expanded system integration\u003c\/li\u003e\n\u003cli\u003eDirect burial rated cable reduces need for conduit in most residential installs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with FM700 and FM702 gate openers only.
