Inductive proximity switches are used for the monitoring of the presence or metal objects. Depending on the switch mode (normylly open/normally closed), the output closes or opens, when the conductive object approaching the active switching zone.

Operation - is maintenance-free. For a fault free operation it is however necessary to keep the following principles: Surfaces of the active switching zone have to be kept free, clean. It is necessary to prevent sediments and other foreign particles from touching and setting up the active surface of the sensor, especially when mounted in upright position (active surface upwards). High electromagnetic field intensity devices (e.g. radiophone) must not be used in the immediate vicinity of the sensors.

Connection of a switch to an electric circuit - Switch connectionmust meet the high protection standard required and resist the high operation temperatures. The proximity switches specified in this catalogue are delivered with 2 x 0.25 mm2, 3 x 0.25 mm2 or 4 x 0.25 mm2 PVC cable in length of 2 m. This type meets the IP 68 enclosure class. The quick-disconnect version is provided with the connector type complying with the IP 67 enclosure class.
