SICK WS12-3D2430 Sensor
SICK WS12-3D2430 diffuse photoelectric sensor, part 2041879. Compact W12 housing for one-sided object detection on conveyors and packaging machines.
Overview
The SICK WS12-3D2430 (part number 2041879) is a diffuse photoelectric sensor in the proven W12 compact housing. It detects objects from one side by evaluating the light they reflect back, which keeps installation simple: no reflector and no second unit are needed opposite the sensor.
How It Works
The sensor emits modulated light and measures how much of it returns from the target. When the received light crosses the set threshold, the output switches. The switching threshold can be adjusted with a potentiometer so the sensor matches both bright and dark targets and the distance available at the mounting point.
Key Features
- One-sided mounting without reflector or receiver unit
- Compact W12 rectangular housing with clear optical axis
- Adjustable sensitivity for adaptation to different targets
- Modulated light suppresses interference from ambient lighting
- Predictable behavior for presence detection on moving lines
- Suitable for continuous operation in industrial environments
Typical Applications
- Presence detection of cartons and totes on conveyors
- Object monitoring between machine stations
- Product detection at packaging machine infeeds
- Level and pile monitoring of containers with sufficient reflectivity
- General automation tasks requiring one-sided mounting

Installation and Setup Notes
Set the sensitivity using the darkest and smallest target that must be detected in production. Remember that rounded or dark objects reflect less light and therefore reduce the effective range. If the background behind the target reflects strongly and causes false switching, replace the diffuse sensor with a background-suppression model such as the GTB6 series.
Frequently Asked Questions
Does the WS12-3D2430 work with black rubber or foam targets?
Dark, porous surfaces reflect little light, so reliable detection requires a shorter mounting distance or a higher sensitivity setting; test with the actual target.
Can it be mounted looking up at objects from below?
Yes, but avoid positions where dust can settle on the lens, and clean the front face during regular maintenance.
Which SICK series is a good alternative if the background causes false trips?
The G6 background-suppression family, for example the GTB6-N1212, ignores backgrounds beyond the switching point.
