SICK GL2S-N2311, part number 1067404, is a retro-reflective photoelectric sensor from the SICK G2 family in the G2 Slim housing. It has a NPN switching output set to light/dark switching, a sensing range of 0.02 m … 3 m and is connected by cable, 4-wire, 2 m. Renda Trading Company supplies it as a genuine SICK part.
A retro-reflective sensor puts the emitter and the receiver in one housing and works against a reflector mounted opposite. That gives it far more range than a proximity sensor while still needing power and wiring on one side only. The polarisation filter lets it detect shiny and film-wrapped objects without being fooled by their own reflections. A PL10F reflector is supplied with the sensor.
The G2 Slim housing measures 7.7 mm x 21.8 mm x 13.5 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 GL2S-N2311
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.
- GL2S 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.
- N is the output: NPN output, light switching. P and N are light switching, F and E are the dark-switching versions of the same electronics.
- 2 is the electrical connection: cable, 4-wire, 2 m.
- The last three digits are the SICK device version, which fixes the sensing range and the optical set-up. On this model that is 311.
The number that matters when ordering is the SICK part number, 1067404, because it identifies exactly one article.
Typical Applications
SICK GL2S-N2311 is used wherever a small, dependable switching signal is needed in a space that will not take a standard sensor. Common jobs include:
- Conveyors and transfer lines where the sensor and reflector can face each other across the track
- Detection of shiny, film-wrapped and transparent-taped packs, thanks to the polarisation filter
- Pallet, box and tote detection at distances up to 3 m
- Door, gate and shutter position control
- Bottling and canning lines where a proximity sensor would be confused by reflections
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 light switching the output is on when the sensor sees the object (or, on a through-beam or retro-reflective sensor, when the beam is clear).

Frequently Asked Questions
What is SICK GL2S-N2311?
SICK GL2S-N2311, part number 1067404, is a G2 miniature photoelectric sensor in the G2 Slim housing. Its functional principle is autocollimation, with polarisation filter, the sensing range is 0.02 m … 3 m, the output is NPN with light/dark switching, and the connection is cable, 4-wire, 2 m.
What is the sensing range of GL2S-N2311?
The maximum sensing range is 0.02 m … 3 m. The reliable working range quoted by SICK is 0.03 m … 2.5 m with PL40A reflector.
Is GL2S-N2311 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 GL2S-N2311 light switching or dark switching?
Light/dark switching. The output is active when the receiver sees light.
How is GL2S-N2311 connected?
The connection is cable, 4-wire, 2 m. 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 GL2S-N2311?
The G2 Slim housing measures 7.7 mm x 21.8 mm x 13.5 mm (W x H x D) and the sensor weighs about 37 g. Enclosure rating is IP67 and the operating temperature range is -25 °C … +50 °C.
Which reflector does GL2S-N2311 need?
A PL10F reflector is supplied with the sensor. The maximum range of 0.02 m … 3 m is stated with a PL40A reflector; a larger reflector gives more range and more tolerance to alignment, while a small one keeps the installation compact. The polarisation filter allows shiny and film-wrapped objects to be detected without false switching.
