Battery Torque Wrench with Digital Torque Settings

Application Characteristics

The advanced battery torque wrench features digital torque settings that allows users to easily increase or decrease the value by 10 ft. lbs. Two buttons are used to set the torque value, which is shown on a four-digit display.

The torque wrench remembers the last set torque value even after the battery has been removed.

 

Offering a torque range up to 3,000 ft. lbs, the torque wrench is suitable for pre-torque and service jobs where electricity or compressed air is not available.

 

Application Requirements

The digital display interface requires an ultra thin display that combines durability with clear character appearance, even in d
ay time. The small LED display needed to draw a low current to reduce power consumption and extend the life of the rechargeable lithium-ion battery. The rugged LED display also required a
long operating life.

 

Solution & Design

VCC’s DSM series was the only that was thin enough to fit the design of the digital torque wrench. The ultra thin SMD LED display is developed on patented technology and is the industry’s thinnest 7-segment display – up to 45% thinner than standard SMD displays.

DSM Series

The DSM Series is available in single digit 7-segment numeric display, in 4 different digit heights (0.20, 0.30, 0,56 or 0.70 inch), and in 2 different bright colors (red or pure green).

 

The DSM Series enables innovative design opportunities due to its minimum thickness of 0.083 inch (2.10mm). It is also packaged in tape and reel for SMT manufacturing to reduce production time and costs.
