Question 1

Match the proximity sensor parameter name with the correct parameter definition.
-Reference Axis

Accepted Answer

The Reference Axis is a line perpendicular to the sensor face and in the center of the sensor surface extending directly away from the sensor, which matches the definition provided in option E.

Question 2

Match the proximity sensor parameter name with the correct parameter definition.
-Sensing Distance

Accepted Answer

Sensing Distance is defined as the distance from the sensor's reference plane to the point where the standard object triggers the sensor to change its output state from off to on.

Question 3

Match the proximity sensor parameter name with the correct parameter definition.
-Standard Object

Accepted Answer

The standard object is a thin square metal plate used to measure proximity sensor parameters.

Question 4

Match the proximity sensor parameter name with the correct parameter definition.
-Reset Distance or Release Off

Accepted Answer

Reset Distance or Release Distance refers to the point where the sensor changes from on to off as the standard object is withdrawn from the sensor, indicating the distance at which the sensor deactivates.

Question 5

Match the proximity sensor parameter name with the correct parameter definition.
-Differential Distance

Accepted Answer

Differential Distance refers to the difference between the resetting distance and the sensing distance, which is essentially the system's hysteresis. This parameter is crucial for understanding how a proximity sensor behaves in terms of its sensitivity and reliability in detecting objects at varying distances.

Question 6

Match the proximity sensor parameter name with the correct parameter definition.
-Setting Distance

Accepted Answer

Setting Distance refers to the maximum sensing distance with a standard object for a sensor under worst-case conditions for supply voltage and ambient temperature.

Question 7

Match the proximity sensor parameter name with the correct parameter definition.
-Frequency Response

Accepted Answer

Frequency Response refers to the maximum rate at which the sensor can detect an object and change its output state accordingly. This parameter is crucial in applications where the sensor needs to track fast-moving objects.

Question 8

Match the proximity sensor parameter name with the correct parameter definition.
-Standard Correction Factor

Accepted Answer

Standard Correction Factor refers to the adjustment made to sensor parameters to account for variations when the detected object differs from the standard or reference object the sensor was calibrated with.

Question 9

Match the statement that describes a sensor type with the name of the sensor mode .
-Photoelectric sensor with light source and receiver packaged in separate housings.

Accepted Answer

Through-beam photoelectric sensors have their light source and receiver in separate housings, allowing them to detect objects when the beam between the two is interrupted.

Question 10

Match the statement that describes a sensor type with the name of the sensor mode .
-Sensor with the greatest sensing distance

Accepted Answer

Through-beam photoelectric sensors have the greatest sensing distance among the options listed because they consist of two separate units: an emitter and a receiver, allowing them to detect objects over longer distances compared to other types of photoelectric sensors.

Question 11

Match the statement that describes a sensor type with the name of the sensor mode .
-Sensor with the light source and
Receiver in the same package and a special target to reflect output light back to the receiver.

Accepted Answer

The retroreflective photoelectric sensor type has the light source and receiver in the same package and a special target to reflect output light back to the receiver.

Question 12

Match the statement that describes a sensor type with the name of the sensor mode .
-Most requently used sensing mode

Accepted Answer

The answer of Match the statement that describes a sensor...

Question 13

Match the statement that describes a sensor type with the name of the sensor mode .
-Best not used when detected object has highly reflective surface.

Accepted Answer

Retroreflective photoelectric sensor types can be affected by highly reflective surfaces, which may cause false readings or detection errors.

Question 14

Match the statement that describes a sensor type with the name of the sensor mode .
-Sensor has filters in front of transmitter and receiver to change transmitted and received light wave alignment.

Accepted Answer

Polarized retroreflective sensors use filters (polarizers) in front of both the transmitter and receiver to ensure that only light which has been polarized in a specific direction by the transmitter and reflected back by a special reflector is detected. This helps to eliminate false signals from shiny surfaces.

Question 15

Match the statement that describes a sensor type with the name of the sensor mode .
-Sensor mode sometimes called photo proximity

Accepted Answer

The answer of Match the statement that describes a sensor...

Question 16

Match the statement that describes a sensor type with the name of the sensor mode .
-Mounting of the sensor is restricted to only one side of the object so the sensor used must be

Accepted Answer

The answer of Match the statement that describes a sensor...

Question 17

Match the the correct lighting configuration with lighting application.
-Direct front lighting

Accepted Answer

The answer of Match the the correct lighting configuration with...

Question 18

Match the the correct lighting configuration with lighting application.
-Diffuse back lighting

Accepted Answer

The answer of Match the the correct lighting configuration with...

Question 19

Match the the correct lighting configuration with lighting application.
-Diffuse front lighting

Accepted Answer

Diffuse front lighting is ideal for applications where eliminating shadows is crucial, as it provides even illumination across the subject, reducing shadows that can obscure details.

Question 20

Match the the correct lighting configuration with lighting application.
-Oblique lighting

Accepted Answer

Oblique lighting is useful for showing surface texture or edge details on objects by casting shadows that highlight these features.
