RIVERSIDE, Calif., November 10, 2010 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced that the company is now offering a new “slip clutch” option in specific multiturn potentiometers models. The slip clutch developed by Bourns for its Models 3547, 3548 and 3549 is designed as a safety feature that helps prevent damage to the potentiometer in applications where the full travel is used thereby increasing reliability and reducing potential service costs and system downtime. Bourns’ multiturn potentiometers with the slip clutch are an optimal solution in mechanized or machine-to-machine applications such as linear actuators, cable transducers and mechanical position sensors where the mechanical actuator may occasionally rotate the shaft beyond the mechanical stops, or beyond the set number of turns.
Bourns® multiturn potentiometer slip clutch option is an internal design feature that does not alter the physical dimensions of the component. This new feature allows the device to idle at the extreme clockwise or counter-clockwise ends without inducing damage to the stops on the potentiometer.

“This unique and useful new feature was developed in response to requests from our industrial, medical and aerospace customers that have the requirement to protect multiturn potentiometers in the event that equipment goes out of calibration,” said Chuck Manzano, product manager at Bourns, Inc. “Bourns is the first to market with this new option and highlights our commitment to product innovation and continuous improvement based on customer feedback. This new option will provide our customers with a more reliable solution in mechanized applications, while providing our customers with added value.”

As a pricing reference, the Model 3547 3-turn and Model 3548 5-turn precision potentiometer with slip clutch option is priced at $16.99-$18.31 in 1,000 piece quantities. The Model 3549 10-turn precision potentiometer with slip clutch option is priced at $14.44-$15.49 in 1,000 piece quantities. Hybritron® versions are also available at higher prices. Samples and production quantities of all three models with the new slip clutch option are available now.

Riverside, Calif., Apr 7, 2009 Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced that the company has expanded its line of circuit protection solutions for industrial applications to include Transient Blocking Unit (TBU) devices. The TBU devices are designed for a broad range of applications including models for industrial, test, security and process control equipment. Designated Bourns C650, C850 and P40 product families, the TBU models feature extremely low energy let-thru and are resettable to provide secure protection for a varying range of power surge threats from lightning and power cross to technician error and factory floor mishaps. Bourns’ TBU devices are compatible with very high speed data buses enabling them to meet speed and bandwidth requirements for reliable power surge protection. The TBU devices also have a very small footprint and meet extremely high equipment uptime requirements in space-constrained applications such as avionics, defense and mass transit applications.

Bourns’ TBU products offer key features required for circuit protection in industrial, test, security and process control equipment applications including speed, bandwidth and resettability. The devices are compatible with faster next-generation chipsets and are resettable within microseconds to provide immediate recovery in critical operations. The TBU devices meet application needs for linearity and high frequency applications to match the demands of high data rate equipment designs.

“Highly dependable circuit protection has been a mainstay for telecommunications applications and it is quickly becoming as equally important for a broad range of industrial and process control applications,” said Dr. Erik Meijer, vice president of circuit protection at Bourns. “Application trends are migrating toward more sensitive electronics with increased demand for improved equipment and process uptime and faster data rates are leading more designers to rethink their circuit protection solutions. Bourns’ TBU devices were designed to meet diverse OEM application requirements for reliable circuit protection under a wide variety of power surge conditions.”

As the only new approach to electronics circuit protection in over a decade, Bourns’ new TBU devices are optimized for 24/7 deployments where circuit protection needs to be immediate to maintain optimal operating functions. Bourns’ TBU technology is designed to immediately block a transient through a current disconnecting mechanism, offering superior protection. TBU technology completely eliminates latency in the circuit protection design, resulting in a fundamentally new and advanced surge protection for sensitive non-telecom applications.
