Small- application combo Lin Engineering, Santa Clara, Calif. |
The company, in conjunction with Trinamic
Motion Control, is introducing the MiniPak. This integrated product combines
a Lin size 11 step motor and a drive/control board using the Trinamic TMC222
drive chip, making it a useful combination for small applications. The Nema
size 11, 1.8-degree motor is 1.1 in. square and comes with a length of 1.24
in. It provides high torque in a small package. The 211-13 produces 9.2
oz.-in. of holding torque. The mounted drive board, which uses the TMC222,
has a programmable coil current of up to 800 mA, a voltage operating range
from 8 V dc to 29 V dc and is capable of 2x to 16x microstepping. The driver
board contains a fixed frequency PWM current control with automatic selection
of fast and slow decay mode as well as a built-in ramp generator for autonomous
positioning and speed control. Another convenient feature is the ability
for on-the-fly alterations of target position. The MCU unit, which is sold
separately, adds RS-485, homing, two-module handling, parameter storage,
constant velocity mode, two demo modes, and ASCII interface. |

| Metal
detection Turck Inc., Plymouth, Minn. |
The uprox+ line of sensors is capable
of precisely detecting materials, such as iron steel, stainless steel, copper,
aluminum, and brass, at high sensing distances without a reduction in the
rated sensing distance of the sensor, according to the company. Uprox+ sensors
contain a newly patented multicoil system. This multicoil system replaces
the wound coil found in conventional ferrite core inductive sensors, resulting
in extended sensing distances (up to 250 percent higher than standard proximity
sensors) and the flexibility to incorporate this technology in a variety
of unique housing designs. Uprox+ sensors also have an integrated predamping
protection function to reduce the metal-free mounting area in applications.
This allows traditionally flush-mounted sensors to be recessed by a half-turn
for increased mechanical protection. Non-flush-mounted sensors may be embedded
in metal up to the outer edge of the thread on barrel-style sensors and
on all four sides of rectangular style sensors, causing only a slight reduction
in sensing distance. Uprox+ sensors satisfy many sensing requirements, according
to the company, whether for the automotive industry, machine engineering
or for transport and handling applications. Uprox+ sensors are capable of
replacing several conventional proximity sensors. |

Floating cable C&M Corp., Wauregan, Conn. |
The company's customized floating
power and control cable is suited for submersible equipment and scientific
devices. The DuraFloat floating cable relies on C&M's proprietary
foam core extrusion capabilities to achieve the manufacturer's precise
cable buoyancy requirements. DuraFloat floating cable is a flexible, UV-stable,
and abrasive-resistant cable, which may also be fitted with a choice of
jackets to achieve resistance to a variety of chemicals, including acids,
saltwater, oil, and gasoline. C&M can vary the foamed core material
and cellular structure of the specified cable to meet an OEM's buoyancy
requirements. As a result, DuraFloat cable minimizes cable weight on submersible
equipment and ensures that the cable does not interfere with equipment operation.
The attributes of this cable make it suitable for powering and controlling
robotic cleaning systems used in swimming pools and aquarium facilities.
It is also suitable for specialized marine applications, oceanography research
instrumentation, submersible environmental pumping systems, and offshore
oil and gas equipment. |

Pressure reducing valve TLV Corp., Charlotte, N.C. |
A compact, lightweight valve, the DR20
is useful with any small to moderate steam requirement. Superior flow characteristics
through the use of a flow-up design, as well as a flat valve and plug arrangement,
promotes secondary pressure stability. The stability augments the pressure
reduction capability to allow the D20 to reach a turnover ratio of 30:1,
virtually eliminating the need for two-stage pressure reduction. The stainless
steel construction of the valve provides high durability and corrosion resistance
for long service life. The DR20 has inline access to internal parts, simplifying
cleaning and maintenance. |

Sheet fanners Eriez, Erie, Pa. |
Strong Hi-Powr sheet fanners are designed
to handle hard-to-handle steel sheets, eliminate doubles, increase production,
and save man-hours. According to the manufacturer, with these sheet fanners,
there is no need to worry about prying, doubles, or marring of polished
and painted sheets. Completely enclosed, tamperproof, and able to withstand
severe usage, Eriez' powerful magnetic circuit makes optimal operating
performance possible. Semi-sticky, oily, bent, and heavy-gauge sheet steel
fan with ease, and provide new efficiency to slow, costly, difficult sheet
feeding to presses, brakes, and shears. There are three strengths available
in four heights, providing coverage for applications up to 1/8- in. (3 mm)-thick
steel; sheets stacked up to 14 in. (355 mm) high. All units are built with
U-shaped frames with stainless anti-friction strips and back cover. |

Anti- microbial fabric duct Ductsox, Dubuque, Iowa |
The Sedona-Xm offers a new aesthetic
matte finish in its anti-microbial fabric duct for office buildings, schools,
hospitals, athletic facilities, retail stores, and other public facilities.
The active anti-microbial agent protects the fabric from mold, fungus, and
other bacterial growth, while it also reduces odors generated by microbial
growths commonly found in HVAC ductwork systems. According to the company,
unlike metal ducts with anti-microbial treatments, the new Sedona-Xm offers
the ability to easily disassemble, launder, and reinstall with minimum reduction
of effectiveness. The new matte finish responds to architect requests for
non-glossy, non-glare polyester duct surfaces. The Sedona-Xm uses linear
diffusers instead of registers to distribute an even, quiet, and draft-less
airflow. It won't attract condensation or dust, doesn't require
painting or special coatings, and is lighter and less expensive to install
than a metal duct. |
