An inductive sensor can detect an element affected by the electrostatic field, which means, it identifies the changes in materials due to the electrostatic field.
A capacitive sensor operates remotely.
Before choosing a capacitive sensor, you must consider several factors:
- the sensor range, that is to say, the distance to which it can detect the object,
- the voltage supply,
- the contact type (NO or NC) and the maximum power supply passing through the dry contact,
Caution, if the contact maximum current is not enough, you must consider using a relay.
- the connector type, either
- wired
- or with a M12 or M8 connector

- if the sensor can be embedded or not; that is to say that the sensor can be put inside a support or not,

- the connection type, either
- a PNP connection switched positive,
- or a NPN connection switched negative, and,
