TRANSDUCER

For linear measurements

The SP2 string-pot transducer is designed for linear measurements in environmentally challenging OEM and testing applications where a compact, single voltage divider device is necessary. It is offered in stroke lengths of 4.75, 12.5, 25, and 50 inches. The product comes standard with 1m of electrical cable affixed with a moisture-protective sheath over the potentiometer.

SCARA ROBOTS

Compact bodies

The TH550 and TH850 scara robots are engineered with high-speed operations, high-payload capacities, and compact bodies. The TH550 reaches composite speeds of 6.21 m/sec, and the TH850 accelerates to 8.03 m/sec. Three-axis speeds for both reach 2,000 m/sec. Positioning repeatability is ±0.015 mm for the X-Y plane of the TH550 and ±0.03 mm for the TH850. Both include a full-function TS controller. Toshiba Machinehttp://rbi.ims.ca/4402-614

DryLin W linear guide systems join the DryLin suite of linear bearings and slides with plastic guide elements. They are available in multiple rail configurations and styles to provide more design options. They are engineered as a low-cost, compact, and easy-to-install solution. With an overall height of 14 mm, the products are available as a combination of two supported round shafts in one profile, in a split rail configuration, or with square rails. igus inc.http://rbi.ims.ca/4402-616

STOCK LIFTERS

For progressive dies

The T2SL series of stock lifters now includes the T2SL-170 model, which is available with either a threaded piston rod or a slotted top plate. Both versions are engineered for use in self-contained mode or hosed system modes. It features all metric interfaces, easily adjustable force, and guidance and lift incorporated into one design. A double tube design isolates the gas spring from the side load. Hyson Productshttp://rbi.ims.ca/4402-617

VIBRATION MONITOR

For outdoor applications

The Octavis vibration monitor product line now includes a durable metal unit for washdown, metalworking, and outdoor applications. It resists oils and coolants, is designed to withstand extreme washdowns. The product is ideal for a variety of applications, including food processing and outdoor equipment monitoring. It incorporates a MEMS accelerometer, A/D converter, DSP, and diagnostic electronics in a 40×40 mm package. ifm efector inc.http://rbi.ims.ca/4402-618

ULTRA-FLAT DC MOTOR

Little inertia, small starting voltages

Two new ultra-flat dc motors, with diameters of 15 and 26 mm and a housing length of 5 or 7 mm, are designed to offer constant torque of up to 3 mNm and speeds up to 10,000 rpm. An ironless rotor with three flat, oval coils revolves with little inertia in an axially-aligned neodymium magnetic field, without cogging or iron loss. The motors may be ordered as geared motorheads with attached spur gear, enabling the drives to have constant torque up to 100 mNm. MicroMo Electronics Inc.http://rbi.ims.ca/4402-619

BUS TECHNOLOGY

Saves money

The company's bus control system is engineered to enable system operators to save money on multiple automated valve installations. It enables actuators in systems that use eight or more electric or pneumatically-actuated valves to be controlled by a PCL with a single pair of wires. The actuators are daisy chained on the same pair of wires, with each actuator assigned a unique address that identifies it to the PLC. Haywardhttp://rbi.ims.ca/4402-620

ROBOTS

Reliable, flexible

The MatriStore automated compound storage and retrieval system is engineered to handle millions of compounds quickly and reliably in cold room environments. The system uses two types of robots: the 4-axis Cartesian robots are used to transfer compounds from original locations to destination locations. The Yamaha scara robots are designed to handle the precise placement of individual samples. MartriCalhttp://rbi.ims.ca/4402-621

MOTORIZED PULLEYS

With integrated encoders

The company's motorized pulleys with integrated shaft encoders are designed to enable conveyor system operators to accurately synchronize product movements. The encoders use SKF or SNR pulse outputs to monitor motorized pulley movement to control conveyor belt speed, position, torque, and rotational direction. They are ideal for a variety of applications, including positioning, cutting, tape winding, adjusting, dispensing, pick and place operations, and constant speed applications.BDL Americahttp://rbi.ims.ca/4402-622

ROTARY BLAST CABINET

Expanded

The RSSA-8 is an expanded rotary blast cabinet for automatic processing of large components that require consistent surface preparation. It is available in specially adapted versions for abrasive blasting, shot peening, nondestructive blast cleaning, cosmetic surface finishing, and media-blast coating removal. The product contains enough cubic space for up to eight suction-blast guns or four pressure-blast nozzles. Guyson Corp.http://rbi.ims.ca/4402-623

STEPPING ACTUATOR

Miniature

The company's size 17 DSM 2344H-C6231 miniature stepping actuator is made of a hybrid step motor and an internal lead screw cut directly into the shaft. It features an M5×2.0 lead pitch configuration that develops a linear force of 13.5 lbs. The motor's front bearing is preloaded to ensure zero backlash performance under light loading conditions, according to the company. The product's step size is 0.4 micro-inches, and the step motor size is 1.65 inches square by 1.34 inches long. Gee Plus Inc.http://rbi.ims.ca/4402-624

SPEED CONTROLLER

Good valueThe DEC 70/10 speed controller is specially developed for the upper performance range where it can control electronically commutated dc motors of up to 700W. The four-quadrant product needs no additional encoder; it operates with the motor's own Hall sensor signals, making it ideally suited for speed and positioning applications. The three operating modes—speed control, voltage control with IxR compensation, and current control—can be pre-selected per DIP switch. Maxon Motorhttp://rbi.ims.ca/4402-625

INCREMENTAL ENCODERS

Reliable operationThe DGS60 incremental encoders are rugged IP-67 products that are available with resolution up to 10,000 pulses. Their design easily accommodates adaptation to suit specific application requirements. They are ideal for machine tool, textile, woodworking, and packaging applications. 6- and 10- mm solid shaft versions are available, and they are also available with through or blind hollow shafts with a connector or cable outlet, and TTL or HTL electrical interfaces.

LINEAR ACTUATORS

New metric stroke

A metric stroke of 31 mm is now available on the Z26000 captive linear actuators. It is available in a range of resolutions, from 0.0127 to 0.1016 mm per step, and it offers up to 4.6 Kg of force. They are designed to allow users to reduce components and simplify designs by replacing rotary motors that generate linear movement through belts and pulleys or rack and pinions. All of the products are designed for low- or high-volume applications. Haydon Switch & Instrumenthttp://rbi.ims.ca/4402-627

THERMOPLASTIC SERVO COUPLING

Durable

At half the cost and half the weight, the TX1 is ideal for any coupling application. Glass fiber reinforced material offers durable construction, and unique geometry dramatically reduces moment of inertia. Torque ranges from 18 to 5840 lbs/inch and bore diameters from .375 inch to 45 mm. R+W Coupling Technologyhttp://rbi.ims.ca/4402-628

SELF-SUPPORTING SYNCHRO-SHAFTING

With free calculation software

At lengths of up to 19 ft without support bearings, the ZA is ideal for mechanical synchronization of parallel run belt driven actuators. Free calculation software allows for verification of application parameters. Torque ranges from 88.5 to 35,400 lbs/inch and bore diameters from 5 mm to 4 inches.
