- Operating Principle: Inductive proximity switches use an electromagnetic field to detect metallic objects, triggering a switching signal when the field is dampened.
- Operating Distances: Various distances are defined, including Rated (sn), Effective (sr), Usable (su), and Assured (sa) Operating Distances, each accounting for different operational conditions and external influences.
- Switch Point Drift and Hysteresis: These ensure stable operation across temperature variations, with hysteresis typically at 10% of sr.
- Switching Frequency and Accuracy: Defined by standard measurement plates and maintaining accuracy within 3% of sr.
- Electrical Characteristics: Include operating voltage, switching current, and protections against short circuits and reverse polarity.
- Environmental Resistance: Sensors are designed to withstand specific temperature ranges and have high protection ratings (IP 68, IP 69K).
- Material and Construction: Often made from stainless steel and PTFE for corrosion resistance.
- Flush and Non-Flush Mounting: Guidelines for installation to avoid interference and ensure proper operation.
- Collocation and Torques: Recommendations for sensor spacing and maximum torques to prevent damage.

Inductive SensorsTerminology for inductive measurement Damping area in % 150 100 75 50 25 12.5 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...

Terminology for inductive measurement flush non-flush free zone free zone Operating voltage 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. Switching current This current gives the maximum long-term current for the switching output of the sensor at an ambient temperature of 25 °C and ohmic load. At an elevated ambient temperature, the current load capability decreases. For analog outputs, the boundary values given in the appropriate...

Inductive SensorsTerminology for inductive measurement 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. Torques In order to...

Application notesMetal face sensors page 3.07 - 3.10 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 solid piece. They detect...
