Product of the Month: Self-Clinching Steel Locknuts

Self-clinching steel locknuts from PennEngineering, Danboro, PA, integrate a unique Tri-Dent® locking feature to hold mating screws tight over time by providing sufficient torsional resistance to withstand vibration, thermal cycling, and other disruptive forces that could loosen the screws in service. The PEM® Type SL™ prevailing torque locknuts, which meet three-cycle locking performance to effectively self-lock the threads of mating screws, further allow for the screws to be removed and reattached repeatedly as needed without compromising the locking threads. The locknuts install permanently in host metal sheets to become integral parts of an assembly. The locknuts are available in thread sizes #4-40 through 3/8-16 and M3 through M10. They are recommended for use in aluminum or steel sheets as thin as 0.040 in. (1 mm) with maximum hardness HRB 80 and HB 150.

Toughened Adhesive

A toughed epoxy for use in industrial applications has been released by EpoxySet, Lincoln, RI. The SetWORX™ 1510 has passed the cytotoxicity tests required by ISO 10993-5, making it ideal for medical device manufacturing. The innovative chemistry yields high bond strength to metals, ceramic, glass, and most plastics. The fast gel time of 15 minutes makes it ideal for production, and its excellent electrical insulating properties are suitable for electronic applications. The epoxy has an easy-to-use 1:1 mix ratio and medium viscosity so it can be dispensed readily through cartridges or through meter mix dispensing equipment.

Linear Servo Motor

Nippon Pulse America, Radford, VA, has introduced one of the smallest linear motors available for high-density applications. The L250SSS linear shaft motor is a 25-mm diameter linear servo motor with a single winding. It uses the company’s smallest available forcer — only 30 mm in length — and its maximum usable stroke reaches more than 2 m in length. The motor is part of the existing SS series, which features small forcers and stack-lengths for high-density applications. The SS series motors are available in 25, 32, and 35 mm shaft diameter sizes, and with single, double, triple, and quadruple winding options. The motors in the SS series are ideal for life sciences and industrial applications in which multiple forcers are required to travel along a single shaft.

Power Supplies

TDK Corporation, National City, CA, has introduced a line of low-profile, triple-output power supplies. Packaged in the industry standard 2 × 4 in. footprint, the TDK-Lambda CUT35 requires no minimum load, simplifying installation. Operating from a universal input voltage of 85–265 Vac, the CUT35 is available in two standard models. The CUT35-522 offers 5V +12 V output voltages, and the CUT35-5FF provides 5V ± 15V with an output power of 35 W. The units can be configured as dual-output power supplies (5V 24V or 5V 30V) by connecting outputs two and three in series. The two-converter topology enables zero minimum load operation and good regulation and provides 500 Vac isolation between the 5-V and secondary outputs. The 5-V output is user adjustable from 5 to 5.25 V and does not impact the secondary output voltage settings.

Differential Oscilloscope

Pico Technology, Cambridgeshire, UK, has introduced a high-resolution differential oscilloscope. The PicoScope 4444 features four true differential input channels and a range of accessories for measurements from millivolt to 1000 V CAT III applications. According to the company, the scope addresses the perennial problem of making accurate voltage waveform measurements on circuit elements that are not ground-referenced, without the risk of short circuits that could damage the device under test or the measuring instrument. A novel intelligent probe interface can also provide power for active probes such as Hall Effect ac/dc type active current probes.

Peristaltic Pump

A peristaltic pump with single-use cartridge technology is available from Watson-Marlow Fluid Technology Group, Falmouth, UK. The Quantum peristaltic pump enables higher downstream process yields throughout the pressure range. The ReNu cartridge enables its aseptic fluid paths to be positioned quickly and accurately ready for use. Flow linearity is achieved across the 43.5 psi (3 bar) SU processing pressure range up to 5.3 gal/min (20 L/min), with trace pulsation of only ±1.74 psi (±0.12 bar), which enables constant pressure, thus maximizing process efficiency and yield. The pump offers ultralow shear and an integrated 4000:1 speed control ratio. The user interface is located at the front of the pump.

LCD User Interface

here , Lake Zurich, IL, has launched a programming-free LCD user interface that allows seamless and code-free integration onto any embedded platform, eliminating the need to write software to control the display. The user interface does not require LCD programming knowledge, which enables users to focus on desired functionality rather than on writing device drivers. The product’s three-button keyboard allows developers to implement a full UI without having to be concerned with reading buttons, debouncing, or programming resources on the host embedded system. The interface includes all control firmware onboard to simplify device design. It contains an ARM M0 processor and free API. Included fonts and user-defined bitmaps allow for addition of 64K color displays to any embedded system.

Miniature Pinch Valves

Clippard, Cincinnati, OH, offers a line of miniature pinch valves. The NPV Series solenoid-operated devices are designed to open and close tubes for controlling flow of liquids and gases. Unlike valves that have internal passages that may cause small amounts of fluid to remain in the valve, these pinch valves have no areas or dead volume where fluid can become trapped. Only the inside of the tubing contacts the fluid. Energizing the solenoid retracts or attracts the plunger, which opens or closes the tube. De-energizing the solenoid allows the plunger to return to its original state.

Brushless Motors

A family of four 12-mm OD micro slotless brushless permanent magnet motors is available from CI Kasei, Tokyo, Japan. The motors have integrated speed control electronics that provide stall or peak torque values ranging from 0.88 mNm (0.125 oz-in) to 1.14 mNm (0.161 oz-in). The shorter C12C-XI-S and C12C-X2-S models use sleeve bearings and operate at 6480 rpm and 7920 rpm, respectively. The ball bearing models, C12C-X2-S-B and C12C-X2-S, are used in applications that handle applications with heavier mechanical loads. Current consumption is below 25 ma. The speed constant varies from 2.14 to 2.16 Krpm/V for the C12C-XI models. All motors are energized at a very low output of 3 Vdc.

Hybrid Servo Motors

A full range of NEMA 23 frame direct drive hybrid servo motors is available from QuickSilver Controls, San Dimas, CA. Four stack sizes provide 80 oz-in (0.56 Nm) through 430 oz-in (3 Nm) continuous torque, with top speeds from 1000 to 4000 rpm. Hybrid servo motors are well suited for direct drive applications because they eliminate the need for gearheads in most applications. These high-torque motors match well to loads in the 500–2000 rpm range, typical of lead screws and belt drives. They provide a significant increase in both power and efficiency over conventional servo motors in these speed ranges. The PVIA control system includes patented damping methods to allow wide ranges of inertial mismatch without retuning or notch filters, reducing the need for inertial matching of the motor to the load.
