? Scan is a skinny technique with generally used in color mark detection
Defuse
When selecting the scan method a photo electric sensor employees to reliably detect a particular object your book list seven considerations what are they
Distance to the object environmental conditions size of object surface of object Materials path Reflectivity
What two factors determine the effective sensing range of a capacitive proximity sensor
Electrical characteristic physical
Which lead controls or triggers and SER to conduct
Gate
What are four types of hall affects sensor actuation
Head on slide by Pendulum Vane
They are two reasons for photocell failure as given in the textbook list them
Humidity Contamination
With a? Thermistor An increase in temperature causes the resistance of the thermistor to increase
PTC
Which of the following is not a type of proximity sensor
Photoelectric
? Scan is a skinny technique which uses a special lens to filter the admitters beam of light so that it is projected in one plain only
Polarized
? Scan of the scanning technique normally used in high vibration applications
Retroreflective
AC photoelectric are connected in? With a load to be controlled
Series
? Scan is a skinny technique which place is the transmitter and receiver at equal angles from a highly reflective surface

Which sensor is a temperature sensitive resistor who is resistance changes with a change in temperature
Thermistor
A? Is a device constructed by to do similar metals that generate a small current when one end heated
Thermocouple
A? Photo electric control is a photo electric control that energize the output switch when the target is missing (removed from the path of the beam )
Light operated
