Inductive & Capacitive Proximity Sensors
- Contactless detection so no mechanical wear compared to a conventional switch
- IP67 rating means that it can operate in liquids up to a depth of 1m
- Wide operating voltage range (10-30V DC) making it ideal for machine and PLC applications
- PNP transistor output resulting in high speed switching
- LED indicator to show when sensor has been activated
What is a proximity sensor?
A proximity sensor is able to detect the presence of nearby objects without any physical contact.
The difference between inductive & capacitive
Inductive sensors are used to detect metal objects. The sensing range is dependent on the type of metal being detected. Ferrous metals, such as steel, allow for a longer sensing range, while nonferrous metals, such as copper, will have a reduced sensing range. Capacitive sensors can detect both ferrous and nonferrous objects but also can detect liquids, powders, granules etc.
What is the difference between shielded (flush fitting) and non-shielded (non-flush fitting)?
The sensing face of the shielded sensors can be mounted flush with the surface that it is mounted on. The sensing face of the
non-shielded sensors has to be clear of any surface to avoid false sensing signals.
