Infrared Motion Sensor SL-OR-CR-203 — 360° detection, adjustable time and lux, black

The Infrared Motion Sensor SL-OR-CR-203 — 360° detection, adjustable time and lux, black is a compact occupancy sensor designed to detect movement across a full 360° field. Housed in a discreet black casing, this sensor uses passive infrared (PIR) technology to respond to changes in infrared radiation caused by human presence. It includes adjustable time delay and ambient light (lux) sensitivity settings so lighting or connected systems operate only when needed. The device is suitable for indoor environments and protected outdoor locations where automatic switching and energy-efficient control of lighting or security loads are required.

Advantages

The SL-OR-CR-203 provides complete radial coverage with its 360° detection pattern, reducing blind spots around the mounting point. Adjustable time delay allows users to set how long the load remains active after motion is no longer detected, while the lux control prevents activation in sufficient daylight, improving energy efficiency. Its compact black housing blends with interior fixtures and minimizes visual impact. The sensor is designed for straightforward wiring and integration with standard lighting or security circuits.

Suitable for

• Corridors, stairwells and hallways
• Storage rooms and utility spaces
• Office common areas and meeting room entryways
• Porches, sheltered entrances and covered outdoor walkways
• Energy-saving retrofits where automatic presence control is required

Key specifications

• Detection angle: 360° radial coverage
• Sensing technology: Passive infrared (PIR)
• Adjustable time delay: user-configurable intervals
• Adjustable lux sensitivity: prevents switching in bright ambient light
• Housing colour: black
• Mounting: ceiling or wall mounting in sheltered locations
• Typical applications: lighting control and presence-triggered switching

How to use

Install the sensor on a stable ceiling or wall surface at the recommended mounting height for optimal 360° coverage, keeping it clear of direct airflow from HVAC vents and away from heat sources. Connect the sensor to the controlled lighting or security circuit following applicable wiring standards and safety regulations. Adjust the lux sensitivity so the sensor does not activate in daylight if that behavior is desired, then set the time delay to the preferred duration for the load to remain on after motion ends. Test the sensor operation after installation and make fine adjustments to the time and lux settings to match the specific environment and user patterns.

Usage recommendations

For consistent detection, mount the sensor where the walking paths are within its radial coverage and avoid pointing it toward reflective surfaces or large glass panes. Use the lux adjustment to avoid unwanted activations from daylight and choose a time delay that balances convenience and energy savings. For outdoor sheltered locations, ensure the enclosure is protected from direct rain and extreme temperature swings that may affect long-term performance.
