High-Pressure Valve

The Model 795 pneumatic dispensing valve from Tridak (Torrington, CT) dispenses very high-viscosity fluids, gels, and pastes that require high pressure to achieve suitable material flow. The valve can be used for silicone gels, greases, adhesives, and sealants. The valve features an adjustable flow control and repeatable fluid dispense cycles. The spool valve is designed to operate with fluid pressure to 2,000 psi (138 bar).

Brushed DC Motors

Maxon Motor (Fall River, MA) offers two new motor sizes with IP54 protection rating and mounting brakes. The commutated DC motors, with output power of 200 and 250W, are protected on the commutation side with sealed aluminum housing. The cable outputs are sealed with PG cable fittings, and the shaft is secured with a radial shaft seal for IP54 rating on the flange side. The motors have diameters of 50 and 65 mm, and are available as standard with various winding options. They achieve nominal torque of up to 0.9 Nm, nominal speeds of up to 5,500 RPM, and an efficiency level of more than 90%.

Linear Actuator Drive

Haydon Kerk Motion Solutions (Hollis, NH) offers the PCM4806 IDEA™ programmable linear actuator drive that is RoHS compliant and optimized to regulate a low-current power stage suitable for controller can-stack linear actuators. The compact electronic drive and fully programmable control unit feature a graphic user interface. Programming the drive is through the use of onscreen buttons instead of command sets or proprietary programming languages. The user interface features automatic population of the motor and drive parameters. Default values can be adjusted as long as they remain within the safe range calculated by the software. Other features include programmable current control, a single supply voltage of 12 to 48 VDC, 0.6Arms max rated current per phase, and 8 opto-isolated general-purpose I/O. The inputs are rated for 5 to 24 VDC, 4mA max per input.

Piezo Driver

Newport Corp. (Irvine, CA) offers the XPSDRVP1, an XPS-compatible driver card for the piezoelectric stack-based NanoPositioning line of sub-nanometer-resolution stages. The driver eliminates the need for either an XPS pass-through card or an independent piezostack driver. An erasable programmable readonly memory (EPROM) stores the stage parameters in the connector, which also has embedded ESP plug-and-play technology that auto-uploads the stage ID and all necessary stage settings to the XPS. The single-axis driver features 60mA peak current, with an internal loop rate of 4 kHz. It can drive both open loop and closed loop NanoPositioning stages equipped with strain gage position sensors.

MEMS Inclinometer

TURCK (Minneapolis, MN) offers the Q42 dual-axis inclinometer sensor with a CANopen interface for angular tilt detection, and angle measurements of ±10, 45, and 60 degrees. The device measures angular tilt in reference to gravity. It features a MEMS device that incorporates a microelectromechanical capacitive element into the sensor that utilizes two parallel plate electrodes — one stationary and one attached to a spring-mass system. Movement causes acceleration that produces deflection in the non-stationary electrode. This results in a measureable change in the capacitance between the two plates that is proportional to the angle of deflection. All measured values and parameters are accessible via the object directory. The micro board design in the MEMS technology allows for a compact device in an industrialized package.

Single-Axis Accelerometer

Kistler Instrument Corp. (Amherst, NY) offers the Type 8640A miniature, single-axis, IEPE PiezoBeam® accelerometer for the multi-channel modal and structural analysis of small or thin-walled structures and components. Offered in ranges of ±5 g, ±10 g, and ±50 g, with sensitivities from 100 to 1000 mV/g, the unit weighs 3.5 grams. Its internal ceramic cantilever beam sensing element is thermally compensated and is supported by a center post that emits an electrical charge when bended during exposure to vibration. Sensing elements are housed in a durable, hermetically sealed welded titanium housing. The accelerometer features an integral 10-32 connector. Units are ground-isolated when mounted with the optional mounting twist-clip or adhesive mounting adapter.
