Occupancy Sensors

Occupancy sensors help manage connected lighting and equipment based on activity in commercial rooms and indoor areas. Common uses include offices, conference rooms, storage areas, copier rooms, closets, restrooms, classrooms, lounges, and broader monitored spaces where automatic control can be paired with manual switching, daylight response, dimming, or HVAC relay connections.

Helpful Buying Guide

Choose an Occupancy Sensor for Your Space and Control Setup

Start with the mounting location and the type of load or control system involved. This category includes wall switch and ceiling sensors for lighting control, a plug-in timer for connected equipment, a fixture adapter for sensor positioning, and a power pack for low-voltage sensor installations with ballast and HVAC relay connections.

Use Cases

Match the sensor to the area being monitored

Wall switch sensors suit room-level lighting control from a wall-mounted location. Ceiling sensors provide overhead coverage for monitored areas, while the plug-in timer manages connected equipment in occupied rooms.

How to Choose

Compare mounting, sensing, and coverage

Choose between wallbox, single-gang switch-box, ceiling, fixture-mounted, or plug-in arrangements. Then compare PIR or dual-technology detection, stated coverage, wiring or power requirements, and available control functions.

Applications

Support lighting and equipment control

Products represented here support occupancy-based control in offices, storage areas, copier rooms, closets, conference rooms, restrooms, classrooms, lounges, and larger indoor monitored areas.

Sensor Types

Select a design that fits the installation location

Wall switch occupancy sensors install at the control point and may fit a standard wallbox or single-gang NEMA-style switch box. Ceiling-mounted models provide overhead sensing, with listed coverage from 450 to 1,500 square feet. A fixture-mounted offset adapter positions a compatible sensor below a deep-body fixture, and a plug-in timer connects to powered equipment.

  • Wall switch PIR and dual-technology options for connected lighting
  • Ceiling PIR and dual-technology options for broad overhead monitoring
  • Fixture adapter with 1/2-inch knockout installation and included locknut
  • Plug-in timer with tethered motion sensor and selectable shutoff timing
Detection and Control

Compare PIR and dual-technology sensing options

PIR models detect occupancy for connected lighting control. Dual-technology models combine ultrasonic and PIR sensing. Some sensors are self-adaptive or self-adjusting to simplify setup, and certain models retain settings through non-volatile memory.

  • PIR coverage options listed up to 1,500 square feet
  • Dual-technology coverage options listed at 500 or 1,000 square feet
  • Integrated photocells can help avoid activating lights when natural light is sufficient
  • Manual control, single-relay control, two-lamp switching, and 0-10V dimming are available on select models
Power and Compatibility

Confirm the connection and load-control requirements

Review the installation and electrical details before choosing. Listed models include low-voltage three-wire connections, 24VDC operation, and wall-switch compatibility with specified 120V or 277VAC incandescent, low-voltage, and fluorescent lighting systems. A power pack provides regulated 24 VDC power for an occupancy sensor and relay-based ballast load control, with dedicated HVAC relay contacts.

  • Ceiling sensors may use low-voltage connections
  • A power pack can control a single luminaire or multiple luminaires
  • The power pack handles listed ballast loads up to 20A at 120, 230, or 277 VAC, or 15A at 347 VAC
  • The fixture adapter supports compatible sensor placement below deep fixture bodies
FAQ

Common questions before buying

What is the difference between PIR and dual-technology occupancy sensors?

PIR sensors use passive infrared occupancy sensing. Dual-technology models combine ultrasonic and PIR sensing.

What coverage areas are represented by these occupancy sensors?

Listed ceiling PIR options cover up to 450 or 1,500 square feet, while listed dual-technology options cover up to 500 or 1,000 square feet.

Can these sensors help avoid turning lights on in daylight?

Select models include an integrated photocell or ambient-light override to help prevent lighting activation when natural light is sufficient.

Are there occupancy controls for connected equipment as well as lighting?

Yes. The plug-in timer uses a tethered motion sensor to control connected equipment, including a connected power strip, after the selected time interval when the space is unoccupied.
