360° High Bay Fixture Mount Line Voltage PIR Occupancy Dimmer Ceiling Sensor | 120/277V | Enerlites MPC-50HD

The ENERLITES MPC-50HD 360° High Bay Fixture Mount Line Voltage PIR Occupancy Dimmer Ceiling Sensor is a commercial-grade lighting control solution engineered for high bay and fixture-mounted applications using 0–10VDC dimmable lighting systems. Designed to maximize energy efficiency while maintaining occupant comfort, the MPC-50HD combines advanced Passive Infrared (PIR) motion detection with intelligent dimming control.

Unlike standard occupancy sensors, the MPC-50HD features four selectable operating modes, allowing it to seamlessly integrate with 0–10V dimmable LED, fluorescent, and high bay luminaires. This flexibility makes it an ideal choice for applications that require automatic ON/OFF control, daylight harvesting, and dim-to-off functionality in compliance with modern energy codes.

The sensor utilizes interchangeable 360° Fresnel lenses to deliver a wide coverage range of 1,200 to 2,800 square feet, supporting ceiling heights from 8 to 50 feet. When motion is detected, lights automatically turn ON or brighten to the programmed level, and when the space becomes vacant, lights dim or turn OFF after an adjustable time delay. An integrated ambient light sensor prevents unnecessary activation when sufficient daylight is present, significantly reducing energy consumption.

Both time delay and light level sensitivity are fully adjustable to meet site-specific requirements. An optional momentary switch allows for vacancy override when manual control is needed. The built-in LED indicator provides real-time visual confirmation of motion detection during setup and commissioning.

The ENERLITES MPC-50HD is UL listed and compliant with California Title 24, Part 6, making it a reliable and code-compliant solution for warehouses, distribution centers, manufacturing facilities, gymnasiums, and other high-ceiling commercial and industrial spaces. Backed by a 2-year limited warranty, it delivers dependable performance and long-term energy savings.
