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