Model Identifier GTB2S-P5331
Official Part Number 1062930
GTIN Standard 4047084294815

Technical Overview

Miniature photoelectric proximity sensor with precise background suppression. Features visible red PinPoint LED, PNP light switching, and an M8 3-pin pigtail.

Key Features

  • Miniature rectangular housing (7.7 x 21.8 x 13.5 mm) designed for space-restricted industrial installations
  • Reliable background suppression (typically from 38 mm) ignores complex or shiny backgrounds
  • Visible red PinPoint LED (640 nm) provides a precise Ø 3 mm light spot at 15 mm for simple alignment
  • Sensing range up to 36 mm, strictly optimized for 5 to 30 mm detection of small objects
  • Robust PNP light-switching output handling up to 50 mA current
  • IP67 enclosure rating ensures high resistance to dust and liquid ingress
  • Pre-wired 200 mm PVC cable with a 3-pin M8 connector for fast integration and quick-disconnect

10 V DC to 30 V DC supply voltage with < 0.6 ms response time and 800 Hz switching frequency for high-speed automated detection tasks.

Industrial Applications

1. High-Speed Electronics Assembly and PCB Verification

In automated printed circuit board (PCB) assembly and pick-and-place machinery, detecting miniature components moving rapidly on conveyors requires small, precise sensors. The sensor's miniature 7.7 x 21.8 mm footprint easily integrates into compact robotic end-effectors or cramped conveyor sections. Its precise PinPoint LED with a 3 mm spot size reliably detects small electronic components at up to 30 mm, while the 800 Hz switching frequency ensures that even rapidly moving components are detected without delay. The background suppression ignores the underlying metallic conveyor belts.

Problem Solved

Prevents false triggers from shiny conveyor belts while detecting small, fast-moving electronic components in extremely confined machine footprints.

2. Pharmaceutical Packaging and Blister Pack Inspection

In pharmaceutical packaging lines, confirming the presence of pills in blister packs or verifying small cartons requires high precision. The sensor operates precisely in the 5 mm to 30 mm range, looking downward at the passing blister packs. Its background suppression feature (effective from 38 mm) ensures that the sensor triggers on the pill or packaging layer without being fooled by the moving stainless steel machinery directly underneath. The <0.6 ms response time guarantees reliable detection at high line speeds, ensuring zero packaging errors.

Problem Solved

Eliminates false readings from background stainless steel machinery while validating small pharmaceutical packaging at high production speeds.

3. Robotic Gripper Part Confirmation in Micro-Manufacturing

Micro-manufacturing robotics require precise part-in-gripper confirmation before moving to the next assembly stage. The sensor's ultralight 17.5 g weight and miniature ABS housing allow it to be mounted directly onto robotic gripping arms without adding significant payload or bulk. The 200 mm PVC pigtail with M8 3-pin connector offers easy quick-disconnect capabilities on the robot arm. The sensor effectively detects the presence of small, low-remission objects gripped within the 5 to 30 mm zone, while reliably ignoring the opposing metallic gripper jaw.

Problem Solved

Allows direct mounting on lightweight robotic grippers to confirm part presence without adding excessive weight or being triggered by the opposite gripper jaw.
