Lithonia Lighting WSX-WH PIR Occupancy Sensor, 120/277V, White

The Lithonia Lighting WSX-WH is a PIR (passive infrared) occupancy sensor engineered for reliable, automatic lighting control in commercial and institutional spaces. Part of the Sensor Switch line, this sensor detects occupant motion across a coverage area of up to 2025 sq ft, with a maximum detection range of up to >36-ft, and operates on dual 120/277-Volt AC input for flexible installation on standard branch circuits. Finished in white to coordinate with common ceiling and wall finishes, the WSX-WH switches connected lighting loads on and off based on real-time occupancy, helping reduce wasted energy in offices, hallways, restrooms, and other frequently transitioned areas of a building.

Key Features

  • Coverage Area: Detects occupancy across up to 2025 sq ft of floor space for reliable whole-room sensing.
  • Detection Range: Maximum detection range of up to >36-ft, suitable for larger rooms and open areas.
  • PIR Detection Technology: Passive infrared sensing responds to occupant movement and body heat for accurate, dependable switching.
  • Dual Voltage Input: Operates on 120/277-Volt AC, simplifying specification across a range of standard branch-circuit voltages.
  • White Finish: Durable white housing blends with standard ceiling and wall finishes for a clean, unobtrusive appearance.
  • Sensor Switch Line: Manufactured as part of the Sensor Switch occupancy sensor family from Lithonia Lighting.
  • Energy-Saving Control: Automatically switches connected lighting loads based on real-time occupancy, helping reduce energy waste in unoccupied spaces.

Lithonia Lighting WSX PDT WH – Frequently Asked Questions

1) Does the Lithonia WSX wall switch occupancy sensor work on both 120V and 277V circuits?
Yes. The WSX wall switch occupancy sensor takes a dual 120/277V AC input, so the same device drops onto either a 120V branch circuit in a tenant office or a 277V circuit in a commercial building without ordering a different part number.
2) What is the difference between the WSX-WH, WSX PDT WH, and WSX-D-WH?
All three are white WSX wall switch sensors; the difference is the sensing and output. WSX-WH is passive infrared (PIR) on/off. WSX PDT WH is dual-technology, which pairs PIR with a second sensing method for spaces where line-of-sight motion alone is not dependable. WSX-D-WH is PIR with dimming output rather than straight switching, which is the one to specify when the fixtures are dimmable and the spec calls for dimmed control.
3) How big a room will one WSX occupancy sensor cover?
Coverage runs up to 2025 sq ft of floor area with a maximum detection range greater than 36 ft. That is enough for a full open office, a classroom, or a long corridor run from a single switch location. For partitioned spaces, remember PIR needs line of sight to moving occupants, so cubicle walls, tall casework, or an L-shaped room will cut the usable area well below the rated figure.
4) Should I use a PIR sensor or a dual-technology sensor for a restroom?
Restrooms are the classic case for the dual-technology version, WSX PDT WH. PIR alone, the WSX-WH, only sees motion in its direct line of sight, so a stall partition can block it and drop the lights on a seated occupant. Dual-technology adds a second sensing method that keeps picking up occupancy where sight lines are broken. For open offices, hallways, and break rooms where occupants are visible from the switch, the straight PIR WSX-WH is the normal choice.
5) Can I use the WSX sensor switch to dim my lights, or does it only turn them on and off?
Only the WSX-D-WH does dimming. The standard WSX-WH PIR and the WSX PDT WH dual-technology models switch the connected lighting load on and off based on occupancy. If the design calls for a dimmed level rather than full on, order WSX-D-WH.
6) Is the WSX a wall switch replacement or a ceiling-mounted sensor?
It is a wall switch occupancy sensor, meaning it goes in the switch box in place of the existing toggle switch rather than up in the ceiling. That makes it the straightforward route for an energy-code retrofit: you are working at one box instead of pulling new wire to a ceiling sensor and power pack.
7) What part number do I order for a dual-technology WSX in white?
WSX PDT WH is the dual-technology white model from Lithonia's Sensor Switch line. The PIR-only white model is WSX-WH, and the PIR dimming white model is WSX-D-WH.
8) Will the WSX sensor match the white devices already on my walls?
All three WSX models are supplied in white, so they sit alongside existing white wiring devices and plates without a colour mismatch. If you are standardizing a building, the PIR, dual-technology, and dimming versions all carry the same white finish, so mixing sensing types across rooms still looks consistent.
