SICK GTB6-P1231 Photoelectric Sensor | Background Suppression, 30mm

Meta Description:​ SICK GTB6-P1231 background suppression photoelectric sensor. Key specs: 30mm range, PNP, push-pull, 4-pin M8. For precise object detection.

Product: SICK GTB6-P1231 Photoelectric Sensor

The SICK GTB6-P1231 is a compact, self-contained photoelectric sensor featuring Background Suppression (BGS)​ technology. It reliably detects objects within a precise sensing window, ignoring surfaces or objects beyond the set range, making it ideal for exact positioning tasks.

Key Features

• Precise Background Suppression:​ Detects objects only within a defined range; ignores the background.

• Fully Integrated:​ No separate amplifier required; easy to set up and install.

• Compact Housing:​ Small size (12.7 x 30.8 x 20 mm) for space-constrained applications.

• Flexible Output:​ Push-pull output allows for simple wiring.

• Part Number:​ GTB6-P1231

• Sensor Type:​ Photoelectric, Background Suppression (BGS)

• Light Source:​ Red visible light, 620 nm

• Sensing Range:​ 2 ... 30 mm (adjustable)

• Operating Mode:​ Diffuse mode with background suppression

• Supply Voltage:​ 10 ... 30 V DC

• Output Type:​ PNP, push-pull

• Output Function:​ Light-On or Dark-On (selectable via push-button)

• Switching Frequency:​ 500 Hz

• Electrical Connection:​ 4-pin, M8 x 1 connector

• Housing Material:​ Plastic (PBT)

• Protection Rating:​ IP67

• Indicator Lights:​ 1 red LED for switching status, 1 green LED for power

• Adjustment:​ Via push-button for range setting and mode selection

Typical Applications

The GTB6-P1231 is ideal for tasks requiring precise detection distance, such as:

• Detecting the presence/absence of small parts on a conveyor

• Counting objects of a specific height

• Controlling fill levels in small containers

• Robot gripper presence sensing

Configuration Note

The output mode (Light-On/Dark-On) and the exact switching point (within the 2-30mm range) are easily configured via the integrated push-button. The P1231​ variant includes the 4-pin M8 connector. For flush or non-flush mounting variants, refer to other codes in the GTB6 series.

Note: Specifications are for product identification and comparison. For detailed mounting instructions, timing diagrams, and application notes, consult the official SICK GTB6 series datasheet.
