1
A capacitive proximity sensor can detect any target that has a dielectric constant greater than air.
2
Fiber optic cables don't contain any electronics, and carry light not current.
3
The logic where the output is held on for a preset time after the target exits the sensing range is ________.
4
With a smaller than "standard size" target, the sensing range of an inductive proximity sensor ________.
5
The presence of metal causes a change in the oscillation of an inductive proximity sensor.
6
The three main components of a limit switch are the operating head, body, and receptacle.
7
An excess gain of 1.00 is the maximum range of the sensor.
8
The shape of the target can have an impact on the sensing range of an inductive proximity sensor.
9
Load powered sensors are connected in series with the load, and are often referred to as 2-wire sensors.
10
________ outputs are solid state and switch DC loads.
11
RFI signals have no affect on an inductive proximity sensor.
12
A photoelectric sensor that generates an output when the photodetector doesn't see light is in the dark operate mode.
13
Ambient temperature has no affect on sensing range for an inductive proximity sensor.
14
When feedback capacitance is detected, oscillation begins in a capacitive proximity sensor.
15
Inductive proximity sensors have a long sensing range.
16
An inductive proximity sensor can detect metallic targets through non-metallic barriers.
17
A limit switch is an electromechanical device that requires physical contact from a target in order to operate.
18
Contrast is important when detecting semi-transparent objects.
19
________ type of sensor, excess gain is related to the light bouncing back from the reflector.
20
Non-plug-in types are a popular design for DIN rail mounted limit switches.
