The trigger/amplifier circuitry inside the sensor is used to monitor the amplitude of the oscillator, and at certain levels (predetermined levels) the circuitry switches on (or off) the sensor/switch ...

Optically isolated solid-state relays (SSRs) (also called optocouplers or photovoltaic relays) were developed to overcome ...

It only switches ‘on’ when the conductive target covers just over half of the sensitive face. It is ‘off’ when the whole face is covered and when none of the face is covered. Trigger distance varies ...

He also explains that while Hall effect requires a sensor for every switch, the inductive switches don't. "Whatever number of keys you have, you have that number of [Hall effect] sensors to power.

The IC designed by onsemi is being used in HELLA’s Contactless Inductive Position Sensor (CIPOS ®) technology for automotive x-by-wire systems. Throughout their 25-year collaboration, ...
