Description

The Proximity Sensor block represents a simple proximity sensor. The sensing distance Z is defined as the distance normal to the sensor surface at which the sensor detects an object for a given radial offset R, as shown in the following figure.

This figure shows a typical sensing distance curve:

The sensor switches to detect the object if the R and Z inputs are below the sensing curve, in the detection zone.

The output is modeled by an electrical switch which can either be Normally Open (N.O.) or Normally Closed (N.C.) when no object is detected.

Vector of distances from the sensor to the object resolved into a plane tangential to the sensor head.

Vector of distances from the sensor to the object resolved with respect to a normal vector at the sensor head.

Indicates whether the output is Normally Open (N.O.), meaning the output becomes closed only when the object is detected, or Normally Closed (N.C.), meaning the output becomes open only when the object is detected.

Resistance between the + and - ports when the output contacts are closed.

Conductance between the + and - ports when the output contacts are open.
