Fixture Mount Sensors
The SENSORWORX fixture mount occupancy sensor series is an excellent solution for high bay and industrial lighting control. With its universal lens that provides excellent range and density, this sensor removes the need to classify an application as low bay, high bay, or aisleway. Additionally, integrated tabs on its chase nipple reduces installation time and fuss by firmly attaching to a fixture via a standard knockout. SENSORWORX products utilize the latest passive infrared technology and digital signal processing techniques to provide unmatched detection performance.
Sensors detect movement in the infrared energy that radiates from occupants as they move within the devices field-of-view. Once occupancy is identified, the sensor’s internal relay switches power on to the connected lighting. An internal timer is set to keep lights on during brief periods of inactivity, and is reset every time occupancy is signaled. Optional daylight detection is also available that dims or turns off controlled lighting according to the ambient lights levels present in the space.
Line voltage sensors are self-contained units that directly power from and switch 120/277 VAC. In a fixture mount application, they typically control a single fixture.

Sensors with an integrated photocell (models SWX-511) will turn lights on/off depending on the amount of ambient light detected. This operation makes them ideal for lighting near skylights, windows, or large bay doors.
Night Light Operation
To enhance nighttime safety in facilities equipped with 0-10V dimmable fixtures, a NightLight operational mode (NL option) is available on sensors equipped with a photocell (SWX-511). In this mode, fixtures will be dimmed and then turned completely off during periods with sufficient daylight. However, during periods with insufficient daylight (i.e. at night) lights are held at a dimmed level during unoccupied periods.
0-10V dimmable fixtures can be controlled with a high/low/off sequence of operation by adding the High/Low option (HL). With this mode, the sensors will drop the lighting level to a low setting after the occupancy time delay expires. Additional operation (must be enabled) allows the unit after a second time delay to shut the fixture off completely. Alternatively, leaving the sensor’s relay disconnected will cause the fixture to stay at the full dim setting (but never turn completely off) for the duration of the unoccupied period.
Sensors with the daylight harvesting option (e.g. SWX-511-D) are capable of automatically controlling the level of 0-10V dimmable fixtures according to the level of detected ambient daylight. Once fully dim, by default, these sensors will then turn lighting completely off if daylight levels are sufficient to maintain the desired overall lighting level. It is also configurable to have lighting stay at the full dim level and never turn off
- Unit works both in installations where Neutral connection is available as well as installations where only Ground connection is present.
- The unit’s two black wires are interchangeable (i.e. one connects to line power, one connects to load).
Single Phase Wiring
- Dimming wires are present on models with -D, -HL or -NL option
