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