Presence and twilight sensor Steinel US 360 COM1 recessed IP20 square white

Steinel US 360 COM1 recessed presence and twilight sensor is designed for indoor lighting control. The square white unit fits into standard recessed housings and provides 360° motion detection combined with ambient light measurement. It switches lighting automatically when movement is detected and can inhibit switching when there is sufficient daylight, helping to reduce energy consumption in corridors, stairwells, offices and residential areas.

Advantages

The sensor integrates presence detection and twilight functionality in a compact recessed housing, enabling flush installation that maintains clean ceiling or wall surfaces. With full 360° coverage, it reliably detects walking motion in all directions. Built for indoor environments with an IP20 rating, the unit supports automated, daylight-aware switching to prevent unnecessary lighting and contribute to energy-efficient building operation.

Suitable for

• Corridors and hallways in residential and commercial buildings
• Stairwells and landings where omnidirectional detection is needed
• Offices and meeting rooms for absence/presence controlled lighting
• Utility spaces, storage rooms and service areas with intermittent occupancy

When it may not be suitable

This model is intended for indoor use only and carries an IP20 protection rating, so it is not suitable for outdoor or damp locations such as balconies, garages, or unprotected exterior entrances. It is designed for recessed installation and may not fit applications that require surface-mounting or non-standard mounting depths. Environments requiring specialized industrial ingress protection or extreme temperature tolerance may need a different sensor model.

Key specifications

• Detection angle: 360° coverage
• Mounting type: recessed/flush installation
• Functionality: presence (motion) detection and twilight (ambient light) sensing
• Protection class: suitable for indoor use (IP20)
• Color and finish: square white housing

How to use

Install the sensor into an appropriate recessed opening following local electrical codes and the manufacturer's mechanical dimensions. Connect the sensor wiring to the lighting circuit and set the ambient light threshold so the sensor only switches lights when natural light is below the required level. Adjust sensitivity and time delay where available to match traffic patterns—shorter delays for frequently used areas, longer delays for spaces where users remain stationary. Test operation after installation by walking through the detection zone and checking daylight inhibition behavior.

What to consider before purchase

• Confirm recessed mounting depth and cut-out dimensions match the installation location
• Ensure IP20 is appropriate for the intended environment (indoor dry locations only)
• Verify compatibility with the building's lighting control wiring and voltage
• Check required detection coverage and sensor placement to avoid blind spots

Usage recommendations

Place the sensor centrally in corridors or stairwells for optimal 360° detection and set the twilight threshold to prevent daytime switching. For mixed-traffic areas, start with medium sensitivity and a moderate time delay, then fine-tune after observing real-world use.
