New products from Festo, MultiDimension Technology, Sumitomo and Titan Tool Supply.
DRVS Semi-Rotary Drive from Festo

Festo recently introduced their new pneumatic semi-rotary vane drive and matched contactless position sensor.
Standard swivel angles for the DRVS semi-rotary drive are 90, 180, and 270 degrees. Custom swivel angles are possible with a stop bracket accessory. At six bar pressure, the seven different sizes in the DRVS line deliver a torque range of .15 Nm to 20 Nm. The company guarantees overnight shipping for standard DRVS drives, which lowers inventory requirements for OEM.
The SRBS, a compact, contactless magnetic position sensor, attaches to the DRVS via a single cable and three screws. During installation, personnel simply move the vane to the drive’s two positions and with a few clicks of the SRBS push button both positions are located for the position sensing unit.
Repetition accuracy is < .0039 inches (.1 mm).
Through its push button, the SRBS position sensor can be designated PNP or NPN and NO or NC, which allows one part number to cover all the different combinations.

Absolute Rotary Encoder from MultiDimension Technology

MultiDimension Technology recently announced the new TMR3101 digital magnetic rotary encoder featuring Tunneling Magnetoresistance (TMR) sensor technology.
The TMR3101 is a 10-bit high-speed rotary encoder with multiple absolute and incremental output interfaces. It is an ideal choice for motor control, rotary position and speed sensing applications including robotics, drones, smart meters, liquid level meters, smart door switches and electrical toys, offering users enhanced ROI with accurate angular position measurement and relaxed requirement for the design of the magnet and mechanical structure.
“MDT’s new TMR3101 is the first digital absolute magnetic encoder product available on the market based on TMR technology. The TMR3101 offers new alternatives to existing magnetic encoder products with high reliability and outstanding jitter and air-gap tolerance, thanks to the unique technical advantages of our TMR technology,” said Dr. Song Xue, President and CEO of MultiDimension Technology.
The TMR3101’s key features include:
- 360-degree contactless measurement
- Enhanced versatility in multiple high-speed output interfaces SPI/PWM/ABI/UVW/PDI, with 10-bit continuous absolute mode output at 3000 RPM, or 1024-line incremental mode at 10000 RPM
- User programmable through the 4-wire SPI interface
- Pulse width variation less than 10 percent
- Large operating range allowing relaxed tolerance of air-gap or mechanical jitter
- Fine resolution at 0.35 degree
- Operating temperature from -40 to 125° C (-40 to -193° F)
- Compact LGA package in 5x5x0.9mm

HF PCD Milling Cutter from Sumitomo

Sumitomo Electric Carbide’s new HF PCD Milling Cutter provides cutting of aluminum and non-ferrous materials. The HF Series features a high-density design (3 teeth per inch).
The unique double-chamfered cutting edge of the insert eliminates burrs and ensures superior surface finishes. The HF Series achieves a run-out precision of 5µm (0.0002”) or less. In addition, the shape and structure of the wedge clamp’s locating mechanism prevents dislocation from centrifugal force and ensures safety and ease of use.
For reduced running costs, the HF Series offers a drastic increase in the amount of insert regrind (to 0.07”) compared to conventional screw lock types. The HF Series employs an air/coolant through system for improved chip evacuation and a longer tool life.

Diamond & Borazon Grinding Pins from Titan Tool Supply

Titan Tool Supply recently announced the introduction of a line of Micro Diamond and Borazon Grinding Pins designed to meet an increasing demand for extremely small precision ID grinding.
The grinding pins, starting at a 0.016” diameter, are on a carbide shank which provides extra strength and precision. The working ends of the pins are coated with either Diamond or Borazon, using a 500/600 grit on the 0.016” diameter model and 325/400 grit on the 0.020” and 0.024” diameters.
According to Titan’s President, Frank Menza, “We have been receiving more demands from our regular Micro Finishing Tool customers, especially in the ceramics and electronics industries, for grinding pins that can be used in very small openings”. He expects to find applications in other industries such as mold, tool and die making.
