Stepper Drive

Applied Motion Products’ (Watsonville, CA) ST10-Si stepper drive delivers 24 to 80 Vdc with peak outputs to 10 A. The drive is protected against overvoltage, undervoltage, overtemperatures, and external output shorts. Upon start-up, the drive measures motor parameters including resistance and inductance, and uses this information to optimize system performance.

Wire Thread Insert

The Spiralock Drive Notch wire thread insert from Spiralock Corp. (Madison Heights, MI) exhibits no tension loss after 24 hours of continuous vibration testing and no fatigue indication. The inserts are simply threaded into any STI tapped hole, with no tangs to break off, retrieve, or account for. The insert resists shock, vibration, and thermal extremes, and provides improved joint integrity in softer materials such as aluminum, zinc, magnesium, and plastic. The insert also eliminates stress in the parent material and requires no staking, keys, or lock rings to hold them in place.

Product of the Month: Biochemical Sensing Unit

Stratophase (Romsey, UK) introduces the Spectrosens sensing unit for biochemial detection of toxins, viruses, and bacteria in real-time. Based on an optical silicon micro-chip with an integral Bragg grating, Spectrosens uses a fiber optic cable to transmit a conditioned beam of light to the chip. When target agents or contaminants are carried in liquid across the surface, tiny changes in sample composition can be detected by precise and continuous monitoring of the wavelength of light reflected from the sensor. Pre-treating the surface to make it sensitive to certain biological or chemical reactions makes it a biochemical detector. The technology is ideal for food, beverage, and pharmaceutical manufacturing industries, as well as drug discovery and process control.

Connex500™

Objet Geometries, Billerica, MA, has introduced the Connex500™ multimaterial 3D printer based on the company’s PolyJet Matrix™ technology, which provides simultaneous jetting of multiple model materials. The system enables the printing of parts and assemblies made of multiple materials in a single build, and fabricates Digital Materials™ on the fly, enabling the creation of composite materials that have preset combinations of mechanical properties. The printer prints parts with specific Shore A values, a scale used to indicate material hardness in soft, flexible materials. It produces prototypes of products that use over-molding in the manufacturing process, and fabricates translucent models that aid in medical applications by showing nerves, tumors, and other areas of interest. Three printing modes are available: DM mode operates at 12 mm per hour in 30-micron layers; HQ mode builds parts at 12 mm per hour in 16-micron layers; and the HS mode runs at 20 mm per hour in 30-micron layers. Build volume is 500 × 400 × 200 mm.
