Our I/O units are equipped with state-of-the-art capacitive touch sensors!
They have a sophisticated electronics chip with a sigma-delta ADC and are self-calibrating. In this way they work reliably in different housings and behind different covers.
Advantages of GPIO Solutions Touch Sensors:
- insensitive to moisture
- insensitive to dusty / dirty environmental influences
- no moving parts / no mechanical wear
- no color dependency
- less surface dependent than other sensor technologies
- no blind zone
- detect metallic and non-metallic objects, liquids and solids
- can "see through" certain materials (blanket coverage)
- semiconductor technology, long life
- versatile mounting options
Our I/O units are equipped with
- no sensors (for a put-to-light process without feedback)
- one sensor (for any processes without correction message)
- two sensors (for any processes with correction message)
