Industrial Applications

1. Li-Ion Battery Cell Assembly Handling

Deployed in the pneumatic pick-and-place handling systems for lithium-ion battery electrode stacking and sorting. The sensor monitors the vacuum and compressed air lines used by the grippers to move sensitive battery components. Its IO-Link connectivity allows continuous transmission of the 14-bit pressure process data variable to the master controller.

Problem Solved

Standard sensors can introduce trace metals that cause dangerous internal short circuits in lithium-ion batteries. This sensor's specific F1a rating (reduced Cu/Zn/Ni values) eliminates heavy metal contamination risks, while its -1 to 10 bar range allows it to monitor both vacuum grip and positive pressure blow-off states in a single unit.

2. Semiconductor Wafer Cleanroom Transport

Integrated into robotic wafer transfer arms within semiconductor fabrication plants to monitor vacuum levels. The sensor utilizes its programmable window comparator switching function to verify that the gripping pressure is within the exact safe threshold before the robot is allowed to move the expensive silicon wafer.

Problem Solved

Prevents catastrophic wafer drops while maintaining strict environmental purity. The sensor solves the contamination challenge by being certified for ISO 14644-1 Class 4 cleanrooms, ensuring it does not shed particulates into the environment, and its fast 3 ms IO-Link cycle time guarantees immediate system reaction to suction loss.

3. High-Speed Automated Medical Packaging Leak Testing

Utilized in blister packaging machines to monitor pressure decay during non-destructive seal integrity testing. Inert gas or compressed air is injected into the test chamber, and the sensor uses its 4-20mA analogue output or IO-Link interface to monitor pressure stability over a brief testing window.

Problem Solved

Identifies micro-leaks in sterile medical packaging by accurately detecting minute pressure drops. The sensor's high precision (1.5 %FS accuracy and 0.05 %FS/K temperature coefficient) ensures reliable pass/fail decisions, and its dual switchable PNP/NPN outputs can trigger immediate reject mechanisms for faulty packages without requiring complex PLC programming.
