SICK GTB6-N1212 Photoelectric Sensor 1052445
SICK GTB6-N1212 background suppression photoelectric sensor, part 1052445, compact G6 housing for color-independent object detection in tight machine spaces.
Overview
The SICK GTB6-N1212 (part number 1052445) is a compact diffuse photoelectric sensor with background suppression from the G6 family. It detects objects at a fixed switching distance and ignores reflectors behind that point, so the sensor responds to the target itself rather than to the machine frame, guard panels or conveyor wall behind it. The small 12 mm x 31.5 mm x 21 mm housing fits mounting positions where larger photoelectric sensors cannot be installed.
How It Works
Background suppression uses a position-sensitive receiver element that evaluates the angle at which reflected light returns. Light reflected from within the set switching distance lands on one area of the receiver and triggers the output, while light from farther surfaces lands elsewhere and is discarded. Because the switching point depends on distance rather than on reflected light volume, the GTB6-N1212 detects dark, shiny or light-colored objects equally well against changing backgrounds.
Key Features
- Background suppression delivers a fixed switching point independent of object color and reflectivity
- Compact G6-format housing, 12 mm x 31.5 mm x 21 mm, for tight machine integration
- Supply voltage range 10 V DC ... 30 V DC for common 24 V control systems
- Precise light spot simplifies alignment on small targets
- Switching point stays stable even when the background is bright or reflective
- Metal threaded mounting sleeve supports secure, repeatable installation
Typical Applications
- Presence checks of workpieces in assembly and machining fixtures
- Object detection on conveyors in packaging and food and beverage lines
- Verification of parts in end-of-arm tooling on robots
- Detection of dark cartons in front of bright machine guards
- Small-part monitoring on automated assembly stations

Installation and Setup Notes
Mount the sensor so the light spot lands fully on the target and use the threaded sleeve to hold alignment after adjustment. Set the switching point with the object in place, then confirm that no closer background surface falls inside the suppressed zone. For diffuse background-suppression sensors, avoid installing the unit where a bright, reflective surface sits just behind the target at nearly the same distance, since both may fall within the evaluated zone.
Frequently Asked Questions
Does the GTB6-N1212 need a reflector?
No. It is a diffuse sensor: the object itself returns the light. A reflector is only required for retro-reflective sensor types.
Can it detect black objects?
Yes. Because background suppression evaluates the distance of the returned light rather than its intensity, dark objects are detected at the same switching point as light ones.
Which supply voltage does it accept?
It operates from 10 V DC to 30 V DC, which covers standard 24 V DC machine power supplies.
