Inductive Sensors Overview
Inductive sensors are used for non-contact detection of metallic objects. They are available in various designs and specifications to suit different applications.

Installation and Operation

Collocation: Maintain a minimum separation between sensors. For flush mounting, the lateral separation should be at least the sensor's diameter. For non-flush mounting, it should be twice the diameter. Oppositely mounted sensors require a separation of six times the rated operating distance.
Torques: Maximum torques for metal and plastic housings are specified to prevent damage during installation. PTFE sensors should be hand-tightened only.

Connection Instructions

Serial Connection: Voltage drops are cumulative, reducing operational voltage. Consider switch-on delay times.
Parallel Connection: Not recommended for two-wire sensors due to added residual currents. For three-wire sensors, the current consumption is cumulative, limited by power supply capacity.

Safety Applications
Sensors used for personal security must comply with EN 61508 and be appropriately labeled.

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...
