Switches & Controls
These multiposition switches connect more than one set of contacts.
What are selector switches?
These switches detect solid or liquid material without making physical contact.
What are proximity limit switches?
These temperature sensors increase resistance as temperature rises.
What are RTDs?
These gauges use a C-shaped tube to measure pressure.
What are Bourdon tube gauges?
These devices are made of solid material and control electron flow without moving parts.
What are solid-state devices?
These switches detect an object when physical contact is made.
What are mechanical limit switches?
These proximity switches use an oscillating magnetic field to detect ferrous metals.
What are inductive proximity switches?
These temperature sensors generate a small DC millivoltage from two dissimilar metals.
What are thermocouples?
These gauges use a thin metal membrane to move the indicator assembly.
What are diaphragm gauges?
This type of proximity switch is best for detecting fluid inside a carton.
What is a capacitive proximity switch?
These switches detect the pressure of air, water, oil, or other media.
What are pressure switches?
These photoelectric sensors have separate transmitter and receiver units.
What are through-beam photoelectric sensors?
These flowmeters use a propeller and magnetic pickup sensor to measure flow.
What are turbine flowmeters?
Micro limit switches commonly have this amperage range.
What is 1 to 20 amps?
These signals provide the positive connection or DC voltage to a PLC input module.
These signals provide the positive connection or DC voltage to a PLC input module.
These switches detect the flow of liquids or gases through a pipe or duct.
What are flow switches?
These photoelectric sensors use one assembly with a reflector to return the light.
What are retroreflective photoelectric sensors?
These flowmeters use a disk that deflects with fluid flow to generate a signal.
What are target flowmeters?
These sensors emit and receive sound instead of light.
What are ultrasonic sensors?
These switches detect the level of liquids, slurries, powders, or paste.
What are level switches?
These switches automatically activate normally open or normally closed contacts when they sense a physical condition.
What are automatic switches?
These devices change the state of their contacts when an object applies enough force.
What are limit switches?
Monitoring motor amperage for robot impact detection has these three disadvantages.
What are the systems are complex and require high-level math, noise can cause false shutdowns, and excessive payload weight can cause shutdowns?
These switches detect the temperature of a solid, liquid, or gas.
What are temperature switches?
These statements describe the limitations of using motor current to detect collisions in robotic systems.
