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