Inductive sensors - Switching amplifiers

  • One- or two-channel design
  • Relay or transistor outputs
  • Small design requiring only very little space for control panel mounting
  • Quick and easy mounting


Switching amplifiers for NAMUR Sensors

NAMUR switching amplifiers evaluate a sensor signal and transmit a switching signal to the controller. They meet the requirements of many international directives for use in hazardous areas.

Switching amplifiers are available with relay outputs, active transistor outputs or potential-free optocoupler outputs. The amplifiers are designed for the connection of NAMUR sensors to DIN EN 60947-5-6 and mechanical switches. They provide the supply voltage for the intrinsically safe circuit.

Switching amplifiers for the conversion of sensor signals

The transistor outputs of conventional sensors are designed for small load currents. If the user wants to switch higher currents or even alternating currents, he must use a switching amplifier It uses the sensor signal to control an output relay.

ifm offers switching amplifiers in one and two-channel design. They have an integrated wide-range power supply (110...240 V AC) to supply the connected sensors with voltage (24 V DC). Thanks to their slim design, the switching amplifiers take up very little space in the control cabinet.
