Description
The Cartell CP4 Free Exit System with 500 ft cable is a professional-grade vehicle detection solution engineered for automatic gate installations requiring extended cable runs and dependable hands-free exit control. Utilizing advanced magnetometer technology, the CP4 accurately detects moving metal vehicles and triggers gate activation without the need for loop detectors, pressure switches, probes, or above-ground sensing devices.
Designed specifically for free-exit automation, the CP4 provides reliable vehicle detection while reducing installation costs and eliminating many of the maintenance concerns associated with traditional loop systems. This version includes an extended 500 ft direct-burial cable, making it the ideal solution for large estates, ranches, farms, industrial facilities, commercial properties, and gate installations where the sensor must be located a significant distance from the gate operator.
The CP4 features adjustable sensitivity settings that allow installers to optimize detection performance based on site conditions and vehicle traffic. Its self-contained underground sensor delivers dependable operation in all weather conditions while maintaining low power consumption, making it an excellent choice for both standard and solar-powered gate systems.
Built for long-term reliability, the sensor features a rugged IP68-rated enclosure and weather-resistant direct-burial cable designed to withstand harsh outdoor environments year after year.
