The SICK GL10-N4112 is a retro-reflective photoelectric sensor from the SICK G10 series. It has a sensing range of 0.15 m to 12 m with a PL80A reflector, a NPN output and an M12 4-pin plug. The housing measures 20 x 50 x 39 mm, runs on 10 to 30 V DC and is rated IP67.
The G10 is the bigger brother of the SICK G6. Same idea, same red PinPoint LED, but a larger optical system and therefore far more range: where a G6 diffuse sensor reaches 250 mm, the G10 reaches 950 mm, and the retro-reflective version works out to 12 m. Use the G10 when the sensor has to be mounted back from the product, when the conveyor is wide, or when a G6 simply does not reach.
The retro-reflective version works against a reflector mounted opposite the sensor and detects the interruption of the returned beam. That gives the longest range of the three, up to 12 m with a PL80A reflector, and detection no longer depends on the colour or the finish of the object. A polarisation filter stops shiny objects from being mistaken for the reflector.
Adjustment is by potentiometer, 270 degrees, the output can be set to light switching or dark switching, and response time is 500 microseconds, which is fast enough for anything a conveyor will throw at it. The housing is ABS with a PMMA lens and the two mounting holes take an M4 screw.
The M12 4-pin plug version is the one to fit where the sensor has to be swapped quickly during production. The cable stays in the machine and only the sensor is replaced.

Frequently asked questions
What does the type code GL10-N4112 mean?
G10 is the SICK compact photoelectric family in the 20 x 50 x 39 mm housing. GTB10 is background suppression, GTE10 is energetic diffuse and GL10 is retro-reflective. The letter after the dash is the output, NPN on this model, and the first digit is the connection: 1 is a 2 m cable and 4 is an M12 4-pin plug. The last three digits are the SICK internal version digits for that model.
What is the difference between the G10 and the G6?
Same red PinPoint LED and the same idea, different size and range. The G6 is 12 x 31.5 x 21 mm and reaches 250 mm diffuse or 5 m with a reflector. The G10 is 20 x 50 x 39 mm and reaches 950 mm diffuse or 12 m with a reflector. Use a G6 where space is tight and the distance is short, and a G10 where the sensor has to be mounted back from the product or across a wide conveyor.
Which reflector does the GL10-N4112 need?
This model is rated at 0.15 m to 12 m with the PL80A reflector, and about 10 m with a P250 reflector. The reflector is not optional, the range figure is only valid with it, so we quote one with the sensor unless you tell us you already have it.
Is the output NPN or PNP, and does it matter?
This model is NPN. The PLC input card decides it, not the sensor. PNP switches the positive line into the input and is the normal choice in Europe and the Middle East; NPN switches the negative line and is common on Japanese and older Chinese machines. Fitting the wrong one means the input never sees the signal.
Can it be used in a washdown or dusty area?
It is rated IP67, which covers dust and temporary immersion, and it copes with a normal factory environment including packaging and bottling lines. It is not rated for high pressure washdown or continuous immersion; for those SICK offers stainless steel and IP69K families and we can quote those instead.
Is this a genuine SICK sensor?
Yes. RendatSP supplies new original SICK parts in factory packaging. This item is type code GL10-N4112. The technical data on this page comes from the official SICK datasheet for this model, and we can send you that datasheet before you order.
Do you ship to Iraq, Saudi Arabia and other Arab markets?
Yes. We ship worldwide from our warehouses and we have local agents in 11 countries, including Saudi Arabia, Iraq, the United Arab Emirates, Egypt, Oman, Libya, Morocco, Mauritania, Yemen, Algeria and Jordan. Send us the type code and the quantity and we will quote delivery to your city.
