SICK GTB6SP-1GA1116EZZZ Photoelectric sensor
SICK GTB6SP-1GA1116EZZZ background suppression photoelectric sensor, part 1141178. Color-independent fixed switching point in a compact G6 SP housing.
Overview
The SICK GTB6SP-1GA1116EZZZ (part number 1141178) is a background-suppression photoelectric sensor of the G6 SP variant family. It combines the compact G6 platform with distance-based switching, providing color-independent detection where the background behind the target must not influence the output.
How It Works
The sensor evaluates the distance of the returned light rather than its intensity. Reflections arriving from within the set switching distance trigger the output; reflections from farther surfaces are suppressed. Object color and gloss therefore have no effect on the switching point.
Key Features
- Background suppression with a fixed switching point
- Detection independent of object color and surface finish
- Compact G6 SP platform for machine integration
- Part number 1141178
- Suitable for mixed-color product streams
- Stable switching in front of machine frames and guards
Typical Applications
- Part presence checks in front of reflective fixtures
- Detection of dark products on bright conveyor backgrounds
- Monitoring of mixed carton colors on packaging lines
- Position verification in compact machine modules
- End-of-arm tooling presence checks

Installation and Setup Notes
Set the switching point with the production target in place and verify that background surfaces remain outside the suppressed zone. Avoid mounting the sensor so close to the background that both fall within the evaluated distance range. Check alignment after mechanical maintenance to keep the switching point accurate.
Frequently Asked Questions
What does the SP designation indicate?
It identifies the special G6 background-suppression variant within the family.
Can it ignore a shiny guard panel behind the product?
Yes, as long as the panel is beyond the set switching distance.
Does it work on transparent objects?
Transparent objects return little light; for reliable transparent detection use a through-beam sensor or a V-optics model such as the WTV4 family.
