2. End-of-Travel Sensing for Miniature Linear Actuators

This inductive sensor provides crucial end-of-travel feedback for compact pneumatic or electric linear actuators. Its M5 x 0.5 thread and 25 mm length allow for easy and direct mounting near the moving components. The 0.8 mm detection range precisely identifies the fully extended or retracted positions, enabling accurate motion control and sequencing in compact machinery where robust and space-saving solutions are required.

Problem Solved

Accurate and non-contact position sensing for miniature actuators to confirm extreme travel limits and prevent overtravel or mechanical damage.

3. Tool Breakage Monitoring in CNC Machining Centers

The NBB0,8-5GM25-E2 is effective for monitoring the presence of small cutting tools, like drill bits or milling cutters, within CNC machining centers. Its IP67 rating and stainless steel housing provide resilience against coolants, lubricants, and metal chips common in machining environments. Positioned close to the tool, its 0.8 mm sensing distance can detect tool presence, immediately signaling a breakage or absence to the CNC controller, thus preventing workpiece damage or machine downtime.

Problem Solved

Real-time detection of small tool breakage or absence in harsh CNC environments to safeguard workpieces and maintain continuous operation.
