Industrial Applications

1. Pneumatic Control in Li-ion Battery Production

Monitoring vacuum and compressed air pressure during the electrolyte filling and degassing processes in lithium-ion battery cell assembly.

Problem Solved

Standard sensors often contain copper, zinc, or nickel, which can contaminate battery cells and cause thermal runaway. This sensor's F1a conformity ensures safe integration without heavy metals, while its -1 to 10 bar range handles both vacuum and pressurized inert gas phases.

2. Cleanroom Semiconductor Wafer Handling

Verifying the correct vacuum level on pneumatic end-effectors used by robotic arms to transport delicate semiconductor wafers in a controlled environment.

Problem Solved

Wafer handling requires strict contamination control and precise vacuum detection to prevent dropping the wafer or triggering false grips. The sensor provides Class 4 according to ISO 14644-1 cleanroom suitability and uses a window comparator switching function to ensure vacuum levels are strictly within safe limits.

3. Automotive Paint-Safe Pneumatic Clamping Monitoring

Monitoring the supply pressure of compressed air for pneumatic clamps holding automotive body panels prior to robotic welding and painting lines.

Problem Solved

Automotive assembly requires components that do not emit Paint-Wetting Impairment Substances (PWIS/LABS) to avoid paint defects downstream. This sensor offers VDMA24364-B1/B2-L LABS conformity while providing exact threshold value comparator outputs up to 10 bar to prevent dangerous under-clamping.
