0-10V Dimming Wall Switch Sensor
The SENSORWORX family of wall switch occupancy/vacancy sensors provides a simple yet cost-effective lighting control solution for many retrofit applications. Designed with contractors in mind, the SENSORWORX 0-10V dimming wall switch sensor is significantly shallower than typical dimmers and sensors, resulting in less crowed wall boxes. Additionally, versatile wiring enables usage with or without a neutral and allows reversal of line and load connections. SENSORWORX products utilize the latest passive infrared technology and digital signal processing techniques to provide unmatched motion detection performance. These units are also available with an integrated microphone to provide overlapping passive acoustic occupancy detection for rooms with obstructions or where occupant motion is limited. For dimming adjustment, intuitive raise and lower buttons are present in a addition to an on/off button.
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. All units can also be configured to operate in Vacancy Mode (e.g., require lights be manually switched on). Once lights are on and if equipped with passive dual technology (PIR/Acoustic), the unit’s microphone is enabled to further enhance detection. An internal timer is set to keep lights on during brief periods of inactivity and is reset every time occupancy is signaled by either the passive infrared or acoustic detection technologies. Ambient daylight detection can also be enabled in equipped units so that lights are held off in rooms with sufficient light contribution from windows or skylights.
A wall switch sensor is typically used to retrofit an existing wall switch in a small room or enclosed space. A Passive Infrared (PIR) only sensor is sufficient for spaces where line of site is maintained and occupants are periodically moving (e.g., copy rooms, storage rooms). Dual technology sensors are necessary where occupants may be partially blocked from the sensor’s direct view or where they may be stationary (e.g., private offices or restrooms with stalls).

Common Energy Code Definitions:
- Occupancy Operation: Auto On/Auto Off
- Vacancy Operation: Manual On/Auto Off
- Partial On Operation:
Auto On to 50%
Users can raise or lower light level manually
30” to 48” (0.76 – 1.22 m) recommended mounting height
Wall to wall (~180 degree) coverage
Small motion (e.g., hand movement) detection up to 20 ft (6.10 m), ~625 ft2
Large motion (e.g., walking) detection greater than 36 ft (10.97 m), ~ 2025 ft2
Overlapping acoustic detection of occupants over entire coverage area
Advanced signal processing filters out nuisance noises while not effecting overall sensitivity
Test mode, 30 sec, 5-30 minutes
5 sec test mode expires after 10 minutes
High-End & Low-End Trim
High-end trim enables energy saving task tuning by setting a maximum level (100%-50%) that which users are allowed to raise lights
Low-end trim enables minimum user level of dimmer to be raised
Turn On/Turn Off Dimming Operation
Sensor turns on lighting to last user level or a preset level (100%, 50%,or custom)
Sensor can turn off lighting by switching off power (by opening relay) or dimming below electronic off level
Lighting can also be held at low-end trim level during unoccupied/off state
Fade On/Fade Off Times
Adjustable time for level to ramp up to turn-on level (0.75 sec, 1.5 sec, 3 sec, 5 sec, or 15 sec)
Adjustable time interval for level to ramp down to off (0.75 sec, 1.5 sec, 3 sec, 5 sec, or 15 sec)
The dimming curve defines how dimmers adjust their voltage output in response to button commands
Linear (default), Square Law, Logarithmic
When enabled, this setting reduces the sensor’s PIR sensitivity for initial turn-ons in order to eliminate false on caused by reflective surfaces like windows
Unit returns to full sensitivity after initial turn-on
SENSORWORX wall switch sensors are intelligent devices that provide both excellent energy savings and enhanced user convenience. Users can choose from several pre-programmed operational modes that best fit their preferences and applicable energy codes.
Manual On / Automatic Off operation. Lights can also be switched off manually. This mode provides increased energy savings but requires the user to initially turn on the lights. Models SWX-103, SWX-104, SWX-123, and SWX-124 default to Vacancy modes.
Automatic On and Automatic Off operation. If lights are switched off manually, the Automatic On functionality is temporarily disabled to allow the person a few seconds to leave the room before switching back to Automatic On operation. However, if the person remains in the space the unit will stay in a manual on state until the switch is pressed again. This mode is the default operation of SWX-101, SWX-111, SWX-121, and SWX-131 models.
Automatic On w/ Exit Time Mode
Automatic On and Automatic Off operation. If lights are switched off manually, the Automatic On functionality is disabled for a fixed 30 seconds.
Override Off Mode
Automatic On and Automatic Off operation until lights are switched off manually, at which point Automatic On functionality is disabled until the switch is pressed again.
Disabled Switch Mode
Automatic On and Automatic Off operation only. Switch functionality to manually turn on/off lights is disabled.
If lights are switched off manually, the Automatic On functionality is disabled until the space becomes unoccupied and the sensor’s time delay expires.
White LED blinks upon occupancy detection
Blue LED serves as a switch locator when lights are off
LED functionality can be disabled
Unit works both in installations where neutral connection is available as well as installations where only ground connection is present.
If no neutral is present, remove the white sleeve from the wire & connect the now Green/Yellow wire to ground (see diagram below).
The White wire (or Green/Yellow wire underneath the removable sleeve) MUST be connected to neutral (or Ground if sleeve is removed) for the unit to operate.
The all Green wire is just for safety.
Never connect Violet or Gray wire to line voltage.
The unit’s two black wires are interchangeable (e.g., one connects to line power, one connects to load).
Neutral to Ground Conversion Detail
- The white wire has a removable sleeve which reveals a green/yellow wire
NOTE: This product is UL listed and meets NEC 404.2(c) & 404.22 guidelines regarding powering over ground & current leakage. Powering over ground is permitted for replacement / retrofit only.
