IFM IM5139-IM5142 Series Inductive Proximity Sensor Switch

Technical Features

Analog proximity switches with precision linear output signal.

Models providing 4…20 mA and 0…10 V analog outputs.

Two corner-mounted LEDs indicate power and switch status.

The sensing surface of the “Cube” proximity switch can be rotated to 5 different directions.

To be used with ifm’s ecolink M12 Micro DC cable connectors.

Applications for Analog Signal Proximity Switches

Analog signal proximity switches can address a wide range of application needs:

Convert Linear Motion to an Analog Signal: Using an analog input card, you can continuously monitor the distance between the proximity switch and the target. Multiple switching points can be programmed if needed.
Classify Products by Material: Different materials have different correction factor curves (the relationship between output and detection distance). If the detection distance is constant, targets made of different materials will produce different outputs, allowing for differentiation.
Classify Products by Height: Targets made of the same material but having different heights or thicknesses can be easily distinguished.
Monitor Concentricity: An analog proximity switch can determine if a rotating object is off-center.

Benefits introduce In Detail

Ifm efector Proximity Switch

The inductive proximity switch series from ifm efector includes models with analog outputs. Both 4-20 mA and 0-10 V output versions are available in rectangular housings. Depending on the model, the linearity tolerance of these proximity switches is ±1% or ±3%.

Linearity describes how well the actual analog output of the proximity switch fits a straight line drawn from the start of the detection range (Smin) to the end (Smax).

LED Indication

The analog signal proximity switch includes a yellow LED. This LED provides a visual status:

LED is ON: The target is within the specified operating range.
LED is FLASHING: The target is not present or is outside the operating range.

Example: A proximity switch has an operating range of 1mm (Smin) to 15mm (Smax). If the distance to the target is less than 1mm or greater than 15mm, the LED will flash. If the target is within the 1mm to 15mm range, the LED will be solidly lit.

Note: This example assumes the target is a standard object. Correction factors for standard materials and dimensions/shapes are applicable to this proximity switch.
