SICK GTB2F-E5141, part number 1093744, is a background suppression photoelectric proximity sensor from the SICK G2 family in the G2 Flat housing. It has a NPN switching output set to dark switching, a sensing range of 1 mm … 9 mm and is connected by male connector m8, 3-pin, 200 mm cable. Renda Trading Company supplies it as a genuine SICK part.
Background suppression is what makes this sensor useful on a real machine. The optics measure where the reflected light lands rather than how much of it comes back, so the sensor sees the object in front of it and ignores whatever stands behind it. A dark box on a bright conveyor belt, a matt part in front of a shiny guard, a black label on a white carton: all of these switch reliably because the decision is based on distance, not on colour or surface finish.
The G2 Flat housing measures 14 mm x 24 mm x 3.5 mm, so the sensor fits into the narrow gaps of packaging machines, small handling units, assembly cells and vending or banking machines where a standard sensor will not go. Protection is IP67 and the electronics are reverse-polarity protected, short-circuit protected and interference suppressed.

How to Read the Type Code GTB2F-E5141
SICK builds the G2 type code from the sensing principle, the housing and the wiring, so once the pattern is clear any part number in the family can be read at a glance.
- GTB2F identifies the sensing principle and the housing. GTB is background suppression, GTE is energetic proximity, GL is retro-reflective and GSE is a through-beam receiver. The digit 2 is the G2 family, and the final letter is the housing: S for G2 Slim and F for G2 Flat.
- E is the output: NPN output, dark switching. P and N are light switching, F and E are the dark-switching versions of the same electronics.
- 5 is the electrical connection: male connector M8, 3-pin on a 200 mm cable.
- The last three digits are the SICK device version, which fixes the sensing range and the optical set-up. On this model that is 141.
The number that matters when ordering is the SICK part number, 1093744, because it identifies exactly one article.
Typical Applications
SICK GTB2F-E5141 is used wherever a small, dependable switching signal is needed in a space that will not take a standard sensor. Common jobs include:
- Very tight installations: the 3.5 mm flat housing slides into slots and channels where nothing else fits
- Slot and cassette detection in vending, banking and ticketing machines
- Small parts feeders, escapements and rotary indexing tables
- Card, sheet and label presence checks
- Machine covers and drawers, where the sensor is mounted flush inside the panel
The NPN output makes it easy to wire into the digital inputs of the usual PLCs. NPN is the normal choice for Japanese and many Chinese machine controls with sourcing inputs. In dark switching the output is on when the object is absent, or when the beam is interrupted.

Frequently Asked Questions
What is SICK GTB2F-E5141?
SICK GTB2F-E5141, part number 1093744, is a G2 miniature photoelectric sensor in the G2 Flat housing. Its functional principle is background suppression, the sensing range is 1 mm … 9 mm, the output is NPN with dark switching, and the connection is male connector m8, 3-pin, 200 mm cable.
What is the sensing range of GTB2F-E5141?
The maximum sensing range is 1 mm … 9 mm. The reliable working range quoted by SICK is 1 mm … 8 mm.
Is GTB2F-E5141 PNP or NPN?
It has a NPN switching output. NPN switches the negative line to the input, which is what many Japanese and Chinese machine controls expect. SICK offers the same sensor with the opposite output under a different type code, so check the model table on this page before ordering.
Is GTB2F-E5141 light switching or dark switching?
Dark switching. The output is active when the receiver does not see light.
How is GTB2F-E5141 connected?
The connection is male connector m8, 3-pin, 200 mm cable. Supply voltage is 10 V DC to 30 V DC with a current consumption of about 20 mA, and the output can drive up to 50 mA. The outputs are short-circuit and overcurrent protected and the supply is reverse-polarity protected.
What are the dimensions of GTB2F-E5141?
The G2 Flat housing measures 14 mm x 24 mm x 3.5 mm (W x H x D). Enclosure rating is IP67 and the operating temperature range is -20 °C … +50 °C.
What is the difference between background suppression and a normal diffuse sensor?
A diffuse (energetic) sensor decides on how much light comes back, so a dark object close by and a bright object further away can look the same to it. A background suppression sensor measures where the reflected light lands on the receiver, which means it decides on distance. It detects dark objects reliably and ignores whatever stands behind them, which is why it is the safer choice on conveyors and in machine fixtures.
Is GTB2F-E5141 a genuine SICK product?
Yes. Renda Trading Company supplies original SICK sensors with SICK part numbers. The data on this page is taken from the official SICK data sheet for GTB2F-E5141, part number 1093744.
