Detection of all solid object by contact Intuitive and easy to install
Dry contact and positive opening contact.
Head could be blocked with external materials (chips, sawdust,...)
Slow actuation speed (<1.5m/s)
Low operating rates due to mechanical contact (~1Hz) wear of contact.
–
Detection of all metals (Fe, Al, Cu, ...) without contacts (no touch)
high operating rates, fast response time and no wear, due to solid state technology for output
Excellent resistance to industrial environments.
Detects only metal objects

4 - Choose the electrical connection
according to facility standards or machine requirements... M12onnector or screw clamp terminal with different tapped cable entries
according to facility standards or machine requirements... Cable, connector (M8, M12 in DC, 1/2» in AC/DC), screw clamp terminals.
Electrical connections
sensors with cable / sensors with terminals
Follow the instruction sheet for electrical connection.
Sensors suitable for flush mounting in metal: No clearance required
The classical choice
Sensors not suitable for flush mounting in metal:
Side clearance required.
Sensing distance greater than that for a standard flush mountable model
Sensors suitable for flush mounting by teaching The maximum sensing distance according to the environnement. Background suppression possible.
