Sensors & Controls

Shop occupancy and motion sensors, photocells, timers, smart controls, wireless remotes, and related automatic controls. Choose by the load being controlled, system voltage, sensing or scheduling method, coverage or response needs, mounting position, wiring, environment, and desired control logic. For manual switching or dimming as the primary task, browse the broader lighting-control and dimmer categories.

Choose the Control by the Behavior You Need

Start with the desired result: automatic-on occupancy control, manual-on vacancy control, daylight response, scheduled operation, countdown control, wireless remote operation, or connected smart control. Then match the product to the connected load, voltage, wiring method, physical coverage, and installation environment.

Occupancy and Motion Sensors

Occupancy controls can automate switching when presence is detected, depending on device mode. Sensor performance depends on mounting position, coverage pattern, room geometry, obstructions, sensitivity, and sensing technology. Use the manufacturer's coverage diagram and installation guidance instead of choosing only by a headline square-foot value. Browse occupancy and motion sensors for room-level applications.

Photocells and Timers Solve Different Problems

Photocells respond to light level, while timers operate from a schedule, time clock, or countdown function depending on the model. Match voltage, load type, contact rating, outdoor rating, and override behavior to the application.

Smart Controls and Wireless Remotes

For app-based control, scenes, ecosystem integration, remote scheduling, or wireless wall stations, compare smart controls and wireless remotes. Protocol, bridge or hub requirements, companion devices, and platform compatibility are product-specific.

Electrical Compatibility Still Comes First

No automation feature overrides the electrical ratings. Confirm line voltage, load type, current or wattage limit, neutral requirement where applicable, wiring arrangement, and environmental rating before selecting the control.

Sensor and Control FAQs

What is the difference between occupancy and vacancy control?

Occupancy control can support automatic-on operation, while vacancy control generally uses manual-on with automatic-off. Exact modes depend on the device.

Is a larger coverage number always better?

No. Mounting height, room shape, obstructions, sensing technology, and the manufacturer's coverage pattern all affect real-world detection.

Can a photocell control any lighting load?

Only when the photocell is rated for the system voltage, load type, current or wattage, and installation environment.
