Industrial Applications

1. Precision Component Sensing in Robotic Grippers

This sensor can be integrated into the end-effector of robotic arms or automated assembly machines to detect the presence or absence of small metallic components. Its compact M8 size and 1.5 mm sensing distance are ideal for precise position feedback, ensuring accurate pick-and-place operations.

Problem Solved

Prevents robots from attempting to grip non-existent parts or ensures a part is correctly seated before further processing, reducing assembly errors and machine downtime.

2. Reliable Piston Position Feedback in Actuators

The NBB1,5-8GM40-Z0 can be mounted flush into the body of pneumatic cylinders to detect the metallic piston's extreme positions (fully extended or fully retracted). Its robust stainless steel housing and IP67 rating ensure reliable operation in environments potentially exposed to dust or splashing liquids from the pneumatic system.

Problem Solved

Provides accurate feedback on actuator position for sequence control, preventing mechanical overtravel or incorrect cycle timing in automated machinery.

3. Metallic Tool Presence Verification in Machining Centers

Given its flush mounting, IP67 rating, and ability to detect metallic objects, this sensor can be used within a CNC machining center to confirm that a metallic cutting tool is correctly loaded into the tool changer or spindle. Its operating temperature range of -25 to 70 °C can handle typical workshop conditions.

Problem Solved

Prevents machine operation with missing or improperly loaded tools, avoiding costly damage to workpieces, tools, and the machine itself.
