Bourns Adds GDT Technology Training Module to its In-Depth Online

September 24, 2013

RIVERSIDE, Calif., September 24, 2013 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced that it has added a new training module on Gas Discharge Tube (GDT) technology to its in-depth online training library. Developed to help engineers solve technical design issues and to select ideal application solutions, the new product training module provides a general overview of GDT technology and relevant industry standards. It also presents the broad portfolio of Bourns® GDT products that make ideal solutions for robust circuit protection in telecom, consumer, industrial, military/aerospace, alternative energy, transportation, medical and automotive applications.

Created as a helpful guide for the overvoltage circuit protection needs of today’s sensitive electronic equipment, Bourns’ new GDT training module examines in detail which devices specifically address the application, performance and cost requirements of a broad range industries and applications. Bournsoffers six major GDT device families and 34 individual product series including a new line of Spactube™ Switching Spark Gap devices, acquired from Jensen Devices, AB. The new devices are designed specifically for voltage controlled switching of capacitive discharge circuits where a high energy, low loss and fast rate of switching performance are required.

Bourns Announces Non-Contacting Torque Sensors Optimized for Automotive Electronic Power Steering Applications

RIVERSIDE, Calif., September 10, 2013 – Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced additions to its new non-contacting torque sensors optimized for electric power assisted steering (EPAS) automotive applications. The new models include Bourns’ torque-only sensor that measures the relative shift angle between two rotating shafts to determine how much power assistance is required; Bourns’ torque angle sensor that collectively measures torque, steering wheel angle and speed; and Bourns’ torque index sensor that includes an additional switch that functions by counting the number of turns of the steering shaft. This torque index sensor enables a more cost-effective solution when the total EPAS system cost is considered. These new non-contacting models feature clock spring-free and Hall Effect (HE)-based technology, which allows measurement without the constraints of a connecting cable for the transmission of power and output signals.

“Bourns has more than ten years’ experience in the production of clock spring-based torque sensors designed for use in a wide range of EPAS applications. Our products have been successfully designed into vehicles from many leading manufacturers” said Jeff Pyle, Vice President – General Manager of Bourns Automotive Division. “The addition of these new non-contacting torque sensors provides our customers with more versatile and cost-effective options that deliver the technologically-advanced solutions our customers have come to expect from Bourns.”

The Bourns’ torque-only sensor (TOS) measures the relative shift angle between two rotating shafts linked by a torsion bar. This angular data is converted into a voltage output and is fed to the EPAS electronic control unit (ECU) to determine how much power assistance is required. This sensor is ideal for applications where a steering angle sensor is already discretely fitted to the column electronic architecture or mounted below the airbag housing. It is particularly useful for column EPAS applications that benefit from the elimination of the connecting cable.

The Bourns torque angle sensor (TAS) has the ability to collectively measure torque, steering wheel angle and speed with a number of steering wheel turns. The upper portion of the sensor contains components for differential torque measurement, and the lower housing uses a set of satellite gears to measure the rate and number of steering wheel turns. The steering angle sensor output is absolute and offers true power-off capability. This sensor is an optimal solution for vehicles that require both torque and steering angle feedback. The TAS sensor design effectively replaces the need to fit two discrete devices.

The Bourns torque index sensor (TIS) offers a cost-effective solution that features an additional HE switch that functions by counting the number of turns of the steering shaft for comparative analysis with an EPAS motor. A motor position sensor (MPS) obtains the relative value of angles from the steering assist motor and by comparing this information; the TIS sensor can accurately determine the absolute value of the steering angle without the use of a discrete steering angle sensor.
