Classical (switching) proximity switches work internally as analog devices, although they produce a binary signal at the output. A large part of the available internal information, though, is lost. Switches with analog outputs, on the other hand, provide the user with full information, permitting a variety of possible applications.

Advantages of Analog technology 

• Very large sensing range
• Available in an economical non-linearized execution with favourable transfer function
• Low specimen scattering
• Current and voltage output in the same device (most models)

 Contrinex inductive analog sensors use Condist technology for particularly large sensing ranges. In addition, these devices are characterized by good switching accuracy, stability, and repeat accuracy, as well as low specimen scattering.

Series 509

Features:

• Large usable sensing ranges of 0…4mm (M8), 0…6mm (M12), 0…10mm (M18) and 0…20mm (M30).
• Excellent resolution (no digitalization)
• Excellent temperature stability
• Voltage and current outputs in the same device for most models
• Low cost, thanks to non-linearized transfer function.

 Applications:

• Regulated approach to end positions
• Several switch points with only one device
• Switch-point setting by teach-in (in conjunction with a PLC)
• Vibration measurement
• Concentricity measurement
