Magnetic Lifting Tool

Bunting Magnetics (Newton, KS) offers the MagFORKLift that works with any type of forklift to move up to 1,100 pounds of material. It attaches to the two forks of a forklift and works in conjunction with four different sizes of Bunting® MagLift™ hand-controlled lifters, which hold, carry, and release loads. The lifters attach to the lifting tool and use permanent magnets to hold. They do not require special cables or electrical hookups. The system can safely handle different shapes and sizes of loads, and concentrate magnetic energy to hold through air gaps and surface coatings. The magnet is “turned on” by rotating the control handle, and a mechanical locking mechanism ensures that it cannot be released accidentally.

DC/DC Controller

Linear Technology (Milpitas, CA) has released the LTC3890/-1 highvoltage, dual-output, synchronous step-down DC/DC controller that draws 50μA when one output is active, and 60μA when both outputs are enabled. With both outputs shut down, the LTC3890/-1 draws 14μA. The 4V to 60V input supply range protects against high-voltage transients, continues operation during automotive cold crank, and covers a range of input sources and battery chemistries. Each output can be set from 0.8V to 24V at output currents up to 20 amps with efficiencies as high as 95%, making it suitable for 12V or 24V automotive, heavy equipment, industrial control, robotics, and telecom applications.

Positioning Sensor

The OLM distance measurement positioning sensor from SICK (Minneapolis, MN) is designed for high-speed positioning of overhead cranes, rail cars, elevators, and other vehicles. The vehicle can be positioned around curves and inclines. The sensor uses a linear bar code tape for positioning, enabling users to position vehicles with 0.1-mm resolution at a distance up to 10 km, providing more than 6 miles of unique positions at increased speed. It features four LEDs and a CMOS camera, and provides easy installation with an integrated skew and tilt angle.

Torque Location Sensor Arm

KolverUSA (Westford, MA) offers the torque location sensor arm, an intelligent system that ensures every screw in an assembly is in the correct location at the right torque. Assembly sequences and X-Y coordinates are programmed with user-interface screens through the keypad. Torque programs are automatically selected and enabled from the screwdriver controller based on the arm locations and current sequence step. This telescoping arm provides the operator full flexibility on the assembly line. Made of carbon fiber, the arm collapses like a telescope. No PC is required.

Motor Identification Chip

B&R Industrial Automation Corp. (Roswell, GA) offers an embedded parameter integrated chip that stores mechanical and electronic motor data such as serial number, type, parameters, and manufacturer specifications, making the entire power transmission system identifiable in an application program. The drive reads the motor data from the encoder. With the data, the encoder automatically determines the current control parameters to ensure optimal control of the motor. The chip supports automatic system configuration, enabling users to field-swap motors without adjusting the drive configuration.

Process Pumps

KNF Neuberger (Trenton, NJ) offers process pumps for fuel cell applications for the delivery of natural gas and pure hydrogen. The pumps feature brushless DC motors and a double diaphragm system. Oil-free operation eliminates the risk of gas contamination. The pumps can achieve maximum flow rates up to 25 l/min, maximum vacuums up to 200 mbar, and maximum pressure up to 15 psig. The area between the two diaphragms may be mounted with a sensor for an immediate indication of failure.

Rotary Encoder

Gurley Precision Instruments (Troy, NY) offers the A08/R108 series rotary encoder that provides both incremental (to 4,096 counts) and absolute (up to 12 bits) position information in an 8-mm-diameter package. Available in both a shaft and blind hollow-shaft configuration, the encoder offers several mounting and interface options. Optional temperature range is available from -40 to 85 ºC, and a radial/axial load of 3N. Output options include an RS-422 differential line driver for incremental applications or SSI with gray-code or natural binary where absolute feedback is required.
