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