Rotary Sensor

Piher North America (Libertyville, IL) offers the MTS 360 SMD rotary position sensor that combines a through-shaft design with 360° absolute position feedback in an ultra-miniature size. The non-contacting sensor measures 6 × 17 × 18 mm, and features reliability to 50 million cycles. The sensor can be integrated on a PCB, and incorporates Hall Effect technology. The offset through-hole accommodates the vacuum pickup tool, allowing use in automated SMD assembly systems. The standard model features a 4-mm double D-flat shaft, and an 8-pad SMD footprint that is compatible in most reflow soldering systems.

Universal Motor Controller

Oriental Motor (Torrance, CA) has introduced the SCX10 single-axis universal stepping motor controller that allows users to operate any motor via three serial communication protocols, including RS-232C, CANopen, and USB interface. It can be used either in an open loop or closed loop system. Standard software allows for program creation by selecting system commands, and start of operation with the click of a start key. The program provides functions such as real-time monitor for the teaching position, current position, and I/O status; system parameter setting; oscilloscope function; and I/O assignment.

Hydraulic Cylinders

J.H. Williams Tool Group, a unit of Snap-on Industrial (Kenosha, WI), offers single-acting lock nut cylinders in diameter sizes from 2 to 12". Units are designed to support loads for extended periods without hydraulic pressure; an overflow port prevents cylinders from travel. Units are 10,000 psi/700 bar with weight capacity ranges to 100 tons. Lightweight aluminum cylinders in diameters from 2 to 12" and double-acting cylinders from 6 to 20" also are available. The double-acting cylinders include rod wipers to seal dirt and other contaminants.

Triaxial Accelerometer

Dytran Instruments (Chatsworth, CA) has released the 3363AT series miniature triaxial accelerometers for modal analysis testing and environmental stress screening. The IEPE-type piezoelectric sensors have a laser-welded titanium design that includes ceramic sensing elements coupled to ultra-low-noise JFET electronics. The accelerometers feature frequency response down to 0.3 Hz, and are available in sensitivities of 10mV/g, 50mV/g, and 100mV/g. They have a 10-32 stud mount, 4-pin radial connector, and are hermetically sealed for normal operation in high-humidity and dirty environments.

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.
