Profile: Rockwell Automation, Inc. specializes in providing industrial automation control and integrated systems. We deal with pumping applications. Our products are flexible & metallic couplings, electric motors, belt drives, enclosed gear reducers and mounted bearings. Encoders are used to electronically monitor the position of a rotating shaft by converting the shaft rotation into electronic pulses. The encoder's output pulses are counted and evaluated by a control unit to determine machine position & velocity. The high mechanical and electronic operating speeds associated with optical encoders increases system speed and decreases cycle times. Our rotary switches are used for electrical isolation of machinery to enable safe access. Once the power has been turned off, the key can then be withdrawn and used in the next sequence of operation such as unlocking an access hatch. The rotary switch can be mounted in a panel. It is available with 4 poles.
