Industrial Applications

1. High-Precision Position Detection in Small Robotic Grippers

This sensor is ideal for precise end-of-travel detection or object presence verification in miniature robotic grippers. Its compact M5 size and 0.8 mm sensing distance allow for accurate operation in extremely confined spaces, while flush mounting ensures it does not interfere with gripper mechanics.

Problem Solved

Ensuring exact positioning and object detection in compact robotic systems where traditional sensors are too large or lack the necessary precision.

2. Safety Interlocking in Hazardous Industrial Machinery

The SIL 2 rating makes this sensor suitable for safety-critical machine guarding systems. It can reliably detect the closed state of a safety gate, providing a NAMUR signal to a safety relay to prevent machine operation if the guard is open, even in harsh industrial environments thanks to its IP67 rating.

Problem Solved

Providing a high-integrity safety feedback mechanism for machine guards in potentially hazardous environments to prevent accidental machine startup.
