The ENERLITES Low Voltage Ceiling Sensor Pir Occupancy Motion Detector offers reliable automatic lighting control for commercial and industrial spaces. Designed with a 360° field of view and coverage area up to 1, 200 square feet, this sensor detects motion effectively in open offices, warehouses, corridors, and storage rooms. Its passive infrared technology responds to changes in heat emitted by people, triggering the connected load only when occupancy is detected. The sensor is engineered for surface mounting on ceilings, providing a discreet and unobtrusive presence. Crafted with a durable thermoplastic housing, the MPC-50L is built to withstand daily wear in high-traffic environments. The unit operates on low voltage (24V AC/DC), making it compatible with most low-voltage lighting control systems and relays. The white finish blends seamlessly into standard ceiling tiles, while the compact dimensions ensure easy installation without excessive protrusion. The sensor features a time delay adjustment ranging from 30 seconds to 30 minutes, allowing customization based on specific room usage patterns. A built-in light level sensor can be configured to prevent activation when ambient light is sufficient, enhancing energy savings. Performance is consistent across a wide temperature range of 0°C to 40°C, suitable for indoor climate-controlled settings. The detection pattern covers a full circle with overlapping zones at typical mounting heights of 8 to 12 feet. This sensor does not include a built-in relay; it is designed to work with an external power pack or control module, making it ideal for integration into existing low-voltage control networks. The wiring terminals are clearly labeled, and the terminal block accepts 14-22 AWG wires, simplifying connections for experienced installers. The product complies with industry safety and performance standards, ensuring steady operation over extended periods. From a value perspective, this detector is exceptionally affordable, offering professional-grade functionality at a fraction of the cost of comparable units. The straightforward wiring and mounting process reduce labor time during installation. Users benefit from reduced energy waste by ensuring lights are on only when needed, lowering electricity bills. The absence of moving parts minimizes mechanical failures, contributing to long-term reliability. This sensor is suitable for retrofit projects where upgrading to occupancy-based control is desired without major rewiring. Its compatibility with common low-voltage systems makes it a versatile component for facility managers and electricians.

The ENERLITES MPC-50L presents a practical solution for occupancy detection in commercial and industrial applications. Its 360° coverage, adjustable time delay, and daylight sensing capability support efficient lighting management. The robust build and competitive pricing reinforce its appeal as a cost‑effective choice for building automation projects. For those seeking reliable motion sensing without advanced features, this detector delivers consistent performance within its defined parameters.
