An inductive proximity sensor configuration that requires a metal-free zone around the sensing face.
An unusable area extending from the face of an ultrasonic proximity sensor to the minimum sensing distance allowing for target detection where pulses are received too quickly to be accurately evaluated.
The surface of an inductive proximity sensor where a high frequency electromagnetic field emerges, although there is no direct magnetic field occurring.
The use of sensors to detect the presence of objects and, through the use of integrated controls, prevent a collision between two objects from occurring.
Another name for fixed focus sensing where the photoelectric sensor will only detect objects at a fixed distance from the sensor.
The use of sensors to transmit data via pulse-modulated light beam systems typically from host stations to mobile carriers such as AGV's or stacker cranes.
The time elapsed between pulse emission and reception that is used to determine target position in an ultrasonic proximity sensor.
The point at which just enough light intensity is present to trigger a photoelectric sensor given the usable area of the lens, For example, an excess gain of two would mean that just enough light intensity is present to trigger a sensor with 50% of the lens obscured with contaminants.
The ability of polarized retro-reflective photoelectric sensors to eliminate false operation as a result of shiny objects.
The ratio of the distance the object travels between the points at which the sensor is turned on and off to the distance the object is from the sensor.
The use of sensors to count the number of objects that pass a particular point in the material handling system for purposes of reconciling actual production or material movement with planned production.
