SICK 1069066 GTB6-P1441S46 PNP Infrared BGS Sensor

Technical Overview

The SICK GTB6-P1441S46 is an infrared photoelectric proximity sensor with background suppression and a PNP light-switching output. Its specified sensing range is 50–350 mm, while the maximum 5–450 mm range is referenced to 90% remission white under DIN 5033. The 850 nm LED forms a 9 mm spot at 100 mm, and a five-turn mechanical spindle adjusts detection. Response is below 1 ms with a resistive load, with 500 Hz switching at a 1:1 light/dark ratio. The 10–30 V DC sensor has a 2 m three-wire PVC cable, M3 mounting holes, ABS/PC housing, PMMA front screen and IP67 protection.

Industrial Applications

1. Checking a component in front of a fixture backplate

An assembly fixture can present a component between the sensor and a more distant backplate. Background suppression and the five-turn adjustment establish a nearby detection region, while the PNP light-switching signal reports the presented component to external inspection logic. Setup verifies actual target remission, seated distance and background separation within the specified sensing range.

Problem Solved

A nearby-target reference helps external inspection logic distinguish a loaded fixture from an empty location even when a more distant backplate remains in view.

Fixture check Background suppression Five-turn adjustment

2. Counting separated parts along a guided conveyor

A guide can keep successive opaque parts at a repeatable distance from the sensor while leaving the more distant machine structure behind them. Each part changes the PNP light-switching state for an external counter. Commissioning verifies target reflectance and separation, and evaluates part transit and gaps against the below-1-ms resistive-load response and 500 Hz rating.

Problem Solved

Distinct part passages provide electrical events to external counting logic, with background suppression helping keep a more distant frame from becoming the selected target.

Part counter 500 Hz PNP output

3. Monitoring continuity of a supported opaque strip

A strip-feeding station can aim the infrared sensor at a supported opaque strip with a more distant surface behind the path. Adjustment places the expected strip within the detection region, and background suppression separates it from that background. External feed logic interprets a sustained absence state as a possible break or runout after material-specific commissioning.

Problem Solved

A strip-present condition gives external feed logic a continuity reference, helping identify loss of material while the sensor and wiring remain on one mounting side.
