ENERLITES MPC-50L Low Voltage Sensor
The MPC-50L is a ceiling-mounted passive infrared occupancy sensor designed for low-voltage lighting control in commercial and industrial environments. It delivers a 360° field of view and supports a broad 1,200 sq ft coverage range, making it suitable for open-plan spaces. A adjustable dip-switch allows time delays from 5 seconds to 30 minutes, and sensitivity can be set from 50% to 100%, enabling tailored performance without sacrificing efficiency.
RAYZEEK 12V/24V Low Voltage Ceiling Sensor
This 12V/24V ceiling sensor provides a full 360° field of view and is designed for both residential and commercial spaces. It emphasizes energy efficiency with low voltage operation, helping reduce electricity costs without compromising lighting performance. The unit offers straightforward setup and adjustable time delays to match occupancy patterns, with optional sensitivity and light-sensing configurations.
ENERLITES MDC-50L Dual Technology Sensor
The MDC-50L combines passive infrared with ultrasonic sensing to improve detection accuracy, including small micro-movements such as page flips or typing. Its low-voltage design provides energy efficiency, and the unit supports multiple triggering modes that blend PIR and ultrasonic inputs. Time delays are adjustable via dip switch, ranging from 5 seconds to 30 minutes, to match room usage patterns.
SensorSwitch CM Series Low Voltage Sensor
The SensorSwitch CM is a 360° PIR occupancy sensor designed for small to medium spaces. Ideal for open offices, classrooms, and restrooms, it provides energy-efficient lighting control with no complicated wiring. Mounting is straightforward for ceiling installations, and the device is optimized for detecting movement with a 12 ft radial range when mounted at typical ceiling heights. It is a reliable choice for low-voltage, wireless-ready setups.
Lithonia PP20 Power Pack for Low Voltage Sensors
The PP20 power pack is a central relay system that powers up to 14 compatible low-voltage sensors. It converts higher line voltages to a Class II 15 VDC supply, enabling reliable operation of remote sensors. The unit includes a durable, plenum-rated housing and supports a range of load configurations, making it a scalable backbone for a low voltage occupancy sensor network.
Buying Guide
- Compatibility: Confirm voltage compatibility with your lighting system (low voltage vs line voltage) and ensure the sensor can pair with any required power packs or relays.
- Sensor Technology: PIR provides reliable presence detection; dual-technology (PIR + ultrasonic) improves accuracy for subtle motions and busy environments.
- Coverage and mounting: Consider ceiling height and room size to choose sensors with adequate 360° coverage; verify mounting options fit ceiling tiles or boxes in your space.
- Time delay and sensitivity: Look for adjustable time delays and sensitivity settings to tailor occupancy responses to occupancy patterns and ambient light.
- System scalability: If expanding later, ensure the power pack or central relay supports multiple sensors and easy integration into existing circuits.
- Installation ease: Favor models with screwless or tool-free adjustments and clear wiring diagrams for faster deployment.
- Environmental suitability: Choose sensors rated for commercial or industrial applications if you expect higher traffic, dust, or temperature variation.
- Reliability and durability: Prioritize devices with durable housings and proven long-term performance, especially in high-traffic or utility areas.
