Inductive Sensors Application notes Sensors Page 3.08 – 3.11 Metal face sensors The inductive proximity switches series IGV are used in areas with heavy-duty mechanical loads at the sensor’s face or where seals between face and housing cannot be used. Chips hitting the front or frequently changing coolants or lubricants do not diminish the function of these proximity switches. The variants with a PTFE coating are particularly well-suited for welding lines and similar environments where sensors are exposed to heavy soiling. Metal face switches are manufactured from stainless steel and are one...

Inductive Sensors Technique & Application Terminology Operating principal An inductive proximity switch works with a high frequency oscillating circuit that creates an alternating electromagnetic field on the active sensor surface by means of a coil. When a metallic object nears this field a damping occurs in the oscillating circuit. If this damping exceeds a threshold value, a switching signal is generated. Operating distance The operating distance is the distance between an object and the active sensor surface at which a switching signal is generated. The operating distance depends on the diameter...

Inductive Sensors Technique & Application Terminology/Installation and operation Minimum load current Im The operating voltage is the voltage range within EGE sensors function safely. For a constant voltage supply it is important to make sure that the limits are still observed when the residual ripple is included. The minimum load current is necessary for flawless operation with two-wire devices. Short circuit protection The short circuit protection ensures the sensor against destruction through a short circuit on the output. After removal of the fault, the output is reactivated. Where a maximum...

Inductive Sensors Technique & Application Installation and operation Collocation When collocating the sensors, a minimum separation must be kept between the devices. When in doubt, a test should be conducted under application conditions. For flush mounting the lateral separation between two sensors must correspond to at least the diameter of the sensor. For non flush mounting, the lateral separation from each other must correspond to at least twice the diameter of the sensor. For oppositely mounted sensors, a minimal separation of six times the rated operating distance should be allowed. Serial...
