Industrial Applications

1. Automotive Component Sorting and Handling

Using the Festo SMH-S1-HGPP20/25 sensor mounted on an HGPP gripper to sort automotive components of varying dimensions. The analogue output provides continuous position data of the gripper jaws, enabling the system to identify the specific part size being handled. Its LABS (PWIS) conformity ensures it can be safely used in automotive environments near paint shops.

Problem Solved

Eliminates the need for external vision systems by utilizing the gripper jaw position to verify part dimensions dynamically during handling, while preventing paint contamination in automotive plants.

2. CNC Machine Tending Part Verification

Integrated into robotic CNC machine tending cells, this sensor monitors the precise position of the gripper jaws. The IP65 degree of protection and CRC 2 corrosion resistance allow it to operate reliably in environments with moderate exposure to machining dust and coolants. The analogue signal differentiates between unmachined blanks and finished parts based on their gripped diameter.

Problem Solved

Prevents CNC machine crashes by confirming the correct part state (blank vs. finished) directly through the gripper stroke measurement before loading it into the machining fixture.

3. Fragile Electronics Packaging Measurement

Deployed in automated packaging lines for electronic devices, the magnetic Hall sensor measures the continuous jaw position of the gripper. With its compact design (20g product weight) and 0.5m PUR cable, it fits easily on high-speed delta robots without adding excessive payload. The 5 to 60 degrees Celsius ambient temperature range is ideal for standard climate-controlled packaging environments.

Problem Solved

Solves the challenge of identifying incorrectly sized or stacked fragile electronic components during the pick-and-place process by using real-time analogue jaw position feedback to detect anomalies.
