Enerlites MDC-50L Dual-Technology PIR/Ultrasonic Low-Voltage Occupancy Sensor: MDC-50L-W

The Enerlites MDC-50L is a ceiling-mounted occupancy sensor that automatically triggers the lights when someone enters a room. This convenient product includes an adjustable shutdown timer, making it great for the kitchen, garage, laundry room, or any other part of the home where it’s common to walk in with your hands full.

The MDC-50L 360° Dual-Technology Ceiling Mount Sensor combines advanced passive infrared (PIR) and ultrasonic technologies into one unit. The combined technologies help to avoid false triggering. Selectable operating modes allow the sensor to turn a load on, and hold it on as long as either or both technologies detect occupancy. After no movement is detected for the selected time delay, the lights switch off. The MDC-50L is operated on 24V supplied by MPP-24 Power Packs.

Flexible Options For Every Home

The MDC-50L low-voltage occupancy sensor allows you to calibrate its performance based on the needs of any room. Adjust the light level and ultrasonic sensitivity using switches on the rear of the unit to fine-tune operation as necessary. Combined with its dual-technology functionality, this capability makes the MDC-50L one of the most versatile ceiling-mounted occupancy sensors on the market today.


A PIR/ultrasonic occupancy sensor helps you reduce energy consumption while making it easier and safer to move through the home. By ensuring lights shut off when a room is not in use, you’ll conserve energy and reduce your monthly utility bills.
