Multiple Rotation Encoder
Schaumburg, Ill. —E6C-N is a multiple rotation encoder said to offer a number of time-saving, ease-of-use features for a variety of motion applications, including tripping detection of stepper motors, numeric controlled table and stacker crane positioning, and timing control of conveyor lines and packaging machinery.
Universal Level Switch Mount
Ann Arbor, Mich. —QuickPlace is a universal level switch mount for simplifying installation of commonly used liquid level sensors. The device consists of a weighted, fluid tight module for housing the level sensor, with integral terminal block and cabling for connecting the sensor to external controls.
Rate/RPM/Frequency Input DPM
Tucson, Ariz. —Model 210 digital panel meter accepts input signals from magnetic pick-ups, photocells, encoders, proximity detectors, transmitters, and power lines. Its Frequency-Voltage technique converts these inputs to a 0-2 V dc for the 4.5 digit A/D. The F-V system allows frequency measurement and control without the need for specific gear ratios.
Ultrasonic Proximity Sensors
Newton, Pa. —SonicLaser ultrasonic proximity sensors come in 18 models and feature a narrow, concentrated beam angle 2.5° off-center axis. This narrow beam angle is said to render the sensor insensitive to echo interference from surrounding objects. Measuring ranges vary from 3.28 to 26.25 ft.
High Accuracy with Mini Encoders
Allerod, Denmark— Using the latest SMD and bonding technology, these miniature hollow shaft encoders are made with an outer diameter of only 24 mm, and are especially resistant to shock and vibration. They count 2,000 pulses per revolution and a maximum frequency of 200 kHz. Counting the leading and trailing edges of both channels provides four times the resolution, which means that the ...
Corrections – 1998-02-01
In the November 1997 Control Engineering cover article, "Flow Sensing: The Next Generation," Fluid Components International was incorrectly named on page 62.On page 64, in the sidebar "Flow Conditioners Save Piping," Vortab Co. should have been shown as based in San Marcos, Calif. Sam Kresch, Vortab marketing manager, cited a Southwest Research Institute (San Antonio, Tex.
The ‘Other’ Web, It’s Not Just a Spider’s Playground
Web processing encompasses a myriad of products and materials that are manufactured in flat sheets or rolls. Web process industries produce many products including textiles, paper, and plastic film. They can also perform any number of secondary operations on these base materials. Countertops, flooring, sandpaper, and food packaging materials such as potato chip bags, candy bar wrappers, a...
Limit Switch Embeds Intelligence
Westerville, O. —E50DNA Series limit switches don't require a separate I/O device to communicate over DeviceNet. Sealed NEMA 6P, the products use the same head and operator inventory as other Cutler-Hammer limit switches. Features include: software selectable functions, diagnostics, fault lists with time stamp, and a solid-state actuator that eliminates contact bounce, RFI, and contacts ...
Modular Encoder Provides Position Feedback
Wilmington, Mass.—TK91 modular encoder provides position feedback for motion control applications. Disc line counts are available up to 1,250 lines per rev with optional zero reference. Several English and metric hub sizes up to 3/8-in. are offered. Line driver and amplified analog signals are available .
Programmable Limit Switches
Roscoe, Ill.— PLµS PS-6344 Programmable Limit Switch accepts input from two resolvers to allow independent monitoring and control of different axes of rotary motion, thereby coordinating events between two separate processes. Automatic speed compensation, combined with fast scan times, enable the PS-6344 to quickly respond to changes in line speed and product movement, minimizing ma...
