Pass & Seymour CS50W Wattstopper 2-Wire PIR Vacancy Sensor, White

The Pass & Seymour CS50W is a Wattstopper passive infrared (PIR) vacancy sensor built for manual-on/automatic-off lighting control in commercial and office spaces. This 2-wire sensor requires no neutral connection, simplifying retrofit installations in existing switch boxes, and features an adjustable time delay so lighting shuts off automatically after a space goes unoccupied. A visible LED status indicator confirms sensor operation at a glance. Finished in white with a matte texture, the CS50W blends into standard wall plates and switch locations while helping facilities meet manual-on lighting control requirements.

Key Features

  • Two-Wire Sensor: No neutral connection required, allowing installation in existing 2-wire switch boxes without rewiring.
  • Manual-On/Automatic-Off Control: Occupants manually turn lighting on, and the sensor automatically shuts lighting off when the space becomes vacant, supporting energy-conscious operation.
  • Adjustable Time Delay: Configurable delay setting allows the automatic-off timing to be tuned to the specific space and occupancy pattern.
  • LED Status Indicator: Built-in LED provides a clear visual confirmation of sensor status during setup and everyday operation.
  • Passive Infrared (PIR) Detection: Wattstopper PIR sensing technology detects occupant motion within the coverage area to trigger automatic-off control.
  • Matte White Finish: Clean white finish with a matte texture coordinates with standard wiring devices and wall plates.

Pass & Seymour PAS-CS-50-W – Frequently Asked Questions

1) Does the Pass & Seymour CS50W vacancy sensor need a neutral wire in the switch box?
No neutral is needed. The CS50W is a 2-wire sensor, so it goes into an existing two-wire switch box on the switch leg without pulling a neutral. That is what makes it workable for retrofits in older commercial buildings where the box only has line and load.
2) Will the CS50W turn the lights on by itself when someone walks in?
It will not. The CS50W is a vacancy sensor, not an occupancy sensor: occupants switch the lights on manually and the sensor handles the automatic off once the space goes vacant. If you want lights to come on automatically on entry, you need an occupancy (auto-on) sensor instead.
3) Can the auto-off timing on the Pass & Seymour CS50W be changed after it's installed?
Yes. The sensor has an adjustable time delay, so you can tune how long the lights stay on after the last detected motion to suit the room, whether that's a restroom that empties quickly or a private office. A built-in LED indicator gives visual confirmation of sensor status while you set it up.
4) Is a PIR vacancy sensor like the CS50W the right choice for a restroom, or do I need ultrasonic?
The CS50W uses passive infrared sensing, which needs a line of sight to moving occupants. That works well in private offices, break rooms, storage rooms, closets and conference rooms, and it's listed for restroom use. Where partitions or stalls block the view of the sensor, a dual-technology or ultrasonic sensor holds the lights on more reliably because it does not depend on direct sight lines.
5) What is the exact part number to order for the Pass & Seymour Wattstopper white 2-wire vacancy sensor?
Order it as Pass & Seymour CS50W, manufacturer part number CS-50-W. It's the Wattstopper PIR vacancy sensor in white, 2-wire, and it is sold as a single model with no finish or voltage variants to pick from.
6) Does a manual-on sensor like the CS50W help meet energy code lighting control requirements?
Manual-on, automatic-off is specifically the control behavior energy codes call for in many enclosed spaces, and the CS50W is built to that behavior: the occupant switches on, the sensor switches off after the adjustable delay expires. Confirm the control requirement for your space type against the code edition your jurisdiction enforces.
7) Will the CS50W match the white devices and plates already on my walls?
It's white with a matte texture, which lines up with standard white wiring devices and wallplates, so it blends in when you're swapping a single switch in a run of existing devices. For a facility standardizing finishes across many rooms, that is the only color offered on this model.
