McLennan Releases Miniature B138F Gearmotor McLennan Servo Supplies has brought out a low-cost miniature brushed DC gearmotor from its Italian distribution partner Micro-Motors. The B138F features a durable spur gearbox in a 34mm-diameter moulded-plastic housing with three-point mounting built-in for straightforward installation. A wide range of standard reduction ratios is available, from 12.25:1 to 1470.82:1, with maximum output torque from 1.5 to 50Ncm. It is just 37.5mm long. The sturdy gearmotor boasts a 20N radial-shaft loading with axial shaft load to 5N. Steel-housed gearbox versions are also available for increased application durability. Available in a choice of 6 or 12V DC and with VDR interference suppression included, the motor includes precious metal brushes and flying leads for flexible installation. Alternative windings for application-optimised performance are also available. McLennan has an active stock programme for popular ratios and voltage ratings across the...

Orchid Offers Miniature DC Motor Controller Orchid Technologies' low-cost, miniature, brushless DC motor controller is claimed to pack a large amount of power into a tiny electronics package. The miniature controller is designed to drive 48V brushless DC motors up to 1,400W. Small physical sizes make it possible to develop high torque and operating speeds when overall product size and weight are application limited. The company claims that it combined cost-sensitive engineering with precision power electronics to craft an efficient, high-performing, three-phase power-output stage. Working closely with silicon vendors, Orchid selected FET output-stage devices while matching drive and sensing technology characteristics. It selected an ST7MC microcontroller as the brains of the brushless DC motor controller. The ST7MC's feature-rich complement of flash program store, static RAM, Eeprom, a patented motor controller, timers, analogue-to-digital conversion circuitry and robust pr...

Fox Offers Miniature SMD HCMOS Crystal Oscillators Fox Electronics is offering its integrated SMD HCMOS temperature-compensated crystal oscillators (TCXOs) and voltage-controlled TCXOs (VCTCXOs) in miniature 3.2mm x 2.5mm package sizes. The 3.3V Fox923CH and Fox923CEH series of oscillators eliminate the need for supplementary external circuitry to obtain a HCMOS output. Suitable for timing requirements in applications such as radio-frequency-identification (RFID) readers, utility metering, wireless telecommunications, GPS, data transfer and test and measurement equipment, these new oscillators offer tighter stabilities than traditional oscillators. Stability is +/-2.5ppm over the -30C to +85C operating temperature range, +/-0.3ppm over the 3.3V (+/-5 per cent) supply voltage and +/-0.2ppm over the 15pF load change. The series offers an input current (IDD) of 6mA, an output symmetry of 40 per cent to 60 per cent over a frequency range of 9MHz to 32MHz and typical phase noise from -1...

The CUB5 provides the user the ultimate in flexibility, from its complete user programming to the optional relay output capability. The meter can be programmed as a single or dual counter with rate indication capability. The display can be toggled either manually or automatically between the selected displays. Red Lion CUB5 Series Display has 0.46″ (11.7 mm) high digits. The LCD is available in two versions, reflective (CUB5R000) and backlight (CUB5B000). The backlight version is user selectable for green or red backlighting with variable display intensity. The Red Lion Counter is programmable for one of eight different count modes, including bi-directional and quadrature. When programmed as a dual counter, each counter has a separate scale factor and decimal points. In the counter/rate indicator mode, each have their own scaling and decimal point read-outs in different engineering units. The Red Lion Meter has two separate inputs which provide different functions depending on which...
