Inductive loads - Import export

EGE inductive sensors for high mechanical loads still work trouble-free even after 10 impacts of 8 Joule. The sensor protected by a solid stainless steel sleeve is thus particularly resistant to shock and vibration. They are ideal for areas where standard sensors could be damaged mechanically. EGE offers variants resistant to high pressure cleaning with protection class IP 68/IP69 for use at temperatures up to 110° C and contamination-resistant sensors with PTFE coating. The proximity switches are based on the proven inductive principle and switch con tactless when a metallic object moves close. The sensors are particularly suited for heavy duty use, for example in metal processing, during welding and in mobile machinery.

These half-wave and bridge rectifiers are ideal for installation in the junction boxes of medium-power brake motors, brakes and solenoids. Accessories include flying leads and a range of mounting hardware so that installation on DIN rails is also possible. Encapsulated versions for an extended operating temperature range are available as options. In case of additional DC side fast turn-off, the induction voltage generated by inductive loads is limited within the rectifier.

The rectifier with built-in current sensor for fast turn-off is designed for the operation of electromagnetic devices. It ensures fast turn-on and turn-off. The rectifier with bridge circuit comprises a thyristor and timer. During overexcitation, the rectifier delivers bridge rectified output voltage before changing over to half-wave rectification. On the DC side, the output voltage is enabled by the built-in current sensor which measures the AC current of the connected motor. If the motor is stopped, the rectifier turns off on the DC side as soon as the current falls below the turn-off threshold. The turn-off voltage generated by the inductive load is limited. The rectifier is suitable for connection in parallel with AC motors. The current sensor must be wired into the motor current path in such a way that the current flow created when the motor operates in generator mode will not pass through the sensor. This is crucial to avoid delayed or impaired DC side switching.
