Automax  photoelectric sensors can be divided into three basic types:

1. Diffuse Beam

2. Through Beam
3. Retro-reflective

The specifications of the above mentioned sensors are defined as below.

The use of these systems depends primarily on the application and the operating environment.

Diffuse Beam Sensor type



Diffuse reflective sensors have the light source and receiver in the same head. The light emitted by the source is diffusely reflected by the detected object. A part of this reflection returns to the receiver and changes the switching status of the output when a certain intensity is exceeded. Thus the texture and colour of the object’s surface has a great effect on the detection (pre
sence/absence) of objects.

Through Beam sensors



Through-beam sensors have the light source and receiver in separate heads. The light emitted by the source is analysed by the receiver. Interruption of the light path (caused by an object) is evaluated and results in switching of the output.

Retroreflective sensors



Retroreflective sensors have the light source and the receiver in the same head. The light beam emitted by the source is reflected back to the receiver by a reflector (e.g. triple reflector or reflective foil). Any break in the light path is evaluated by the receiver and in turn results in a change of the output mode.

The reflectivity of the object surface to be sensed effects the sensing distance, so that a correction factor or re-emission factor has to be specified. This value may vary from, less than 10% for matt-black plastic to 200% for raw aluminium sheet metal (special values on request). Usually we recommend an application-dependent test of the specific object to take ambient conditions, such as dust and humidity, into consideration for the selection of the optimum sensor.

Different sensing distances and sensitivity settings are required for different objects (surface, colour)
