Pass & Seymour WS301W Wattstopper PIR Single-Pole Occupancy Sensor, 800W/120V-1200W/277V, White

Pass & Seymour WS301W Wattstopper PIR Single-Pole Occupancy Sensor, 800W/120V-1200W/277V, White

The Pass & Seymour WS301W is a Wattstopper PIR (passive infrared) single pole, single relay occupancy sensor finished in white, engineered to automatically control lighting loads rated up to 800W at 120V or 1200W at 277V. Built for reliable everyday switching, it combines a light level sensor, zero crossing relay circuitry, and voltage drop protection to deliver dependable, energy-saving occupancy control for commercial and light-industrial spaces. Adjustable time delay and sensitivity settings let installers tailor detection performance to the room, while a custom two-tier Fresnel lens improves accuracy at the desktop level.

Key Features

• Electrical Rating: Switches lighting loads up to 800W at 120V or 1200W at 277V for single pole, single relay control.
• Light Level Sensor: Holds connected lights off when ambient daylight is above the preset threshold, reducing unnecessary energy use.
• Zero Crossing Circuitry: Reduces stress on the relay during switching, extending overall sensor life.
• Voltage Drop Protection: Patented protection helps maintain reliable sensor performance over time.
• Adjustable Time Delay & Sensitivity: Configurable settings allow the sensor to be tuned to specific room occupancy patterns.
• Two-Tier Fresnel Lens: Custom lens design enhances PIR detection at the desktop level for more accurate occupancy sensing.
• Finish: Matte White finish for a clean, unobtrusive appearance on walls and ceilings.
• Compact Footprint: Measures 2.6 in x 2.6 in with a 1.75 in width and 1.55 in depth for easy installation in standard electrical boxes.
