Miniature linear actuators
The LE series of actuators have a total assembly height of just 0.785 in. yet have a load-carrying capability of 6 lbs. The LE2-X consists of a low friction ball slide assembly attached via a common base to an anti-backlash nut and a 0.188 in. dia., 0.050 leadscrew assembly. A beamed coupling and motor mount com-plete the assembly. An anti-creep retainer system maintains perfect alignment. Del-Tron Precision Inc, Bethel, CT.  www.rsleads.com/302df-103

Brake actuators
The self-contained Electrastar actuator is powered off a battery, and uses a microprocessor and decelerometer to sense the amount of braking generated by a towing vehicle. The unit automatically adjusts its output so that the amount of trailer braking is in direct proportion to the braking generated by the tow vehicle. These actuators comply with CFR-393 federal braking requirements. Carlisle Industrial Brake and Friction, Bloomington, IN.  www.rsleads.com/302df-104

Smart linear actuators
Smart Digit and Smart Bug linear actuators feature an optical encoder, digital servo amp, indexer, local power supply, serial communications interface and optional absolute position. Smart Digit inline actuators are directly coupled to the drive screw. Smart Bug incorporates a nonslip timing belt with ratios from 1:1 to 4:1. Both lines feature repeatability to 1 micron and resolution to 0.5 microns. Ultra Motion, Mattituck, NY.  www.rsleads.com/302df-105

Custom technical diagrams
Designers considering a “rolling ring” linear motion assembly can submit application requirements via an online form and receive, in turn, custom specifications and diagrams. Technical details include assembly dimensions, linear drive size, vibration analyses, drive power requirements, system life expectancy, shaft sag and critical rotational speeds. Amacoil Inc, Aston, PA.  www.rsleads.com/302df-106

Right angle gear box
The G14 single worm reduction right angle gearbox is suited for applications requiring high output torque and dependability. The gearbox has a continuous torque rating to 60 in.-lbs and speeds to 350 rpm. Features include grease lubrication, ball bearings, (gearbox) foot mounting and high-energy ceramic magnets. The company also supplies five motors that operate with this gearbox. RAE Corp, McHenry, IL.  www.rsleads.com/302df-107

Miniature gearhead
The CSF-1U size 5 gearhead delivers 3 arc-min positional accuracy in a 20 mm² x 47 mm long package. It has a rated torque of 5 in.-lb and a maximum torque of 24 in.-lb. The gearhead has both an input shaft and an output shaft for convenient coupling. The package is available in gear ratios 30:1, 50:1 and 100:1. HD Systems Inc, Hauppauge, NY.  www.rsleads.com/302df-108

Linear actuator
This environmentally sealed linear actuator is designed for extremely harsh operating conditions. Various sizes of hybrid linear actuators are particularly suited for military applications. Forces up to 500 lbs are available with step increments of 0.00006- to 0.005-in. Custom configurations are offered to meet specific application needs. Haydon Switch & Instrument Inc, Waterbury, CT.  www.rsleads.com/302df-109

Motion processor chips
This company has added Acceleration Feed Forward to its software-compatible Navigator family of motion processor chips. The family provides trajectory generation, servo control, pulse and direction generation, commutation and other time-critical functions. The new item is an advanced servo compensation scheme that allows faster system responses, lower dynamic tracking errors and more efficient motor operation. Performance Motion Devices Inc, Lincoln, MA.  www.rsleads.com/302df-110

Peripheral connections
The Serial to DeviceNet Gateway allows existing serial ASCII devices (such as motor controllers) to be connected to DeviceNet. Data can be read/written using either polling or explicit messaging and COS. Setup is simple and intuitive. The feature set includes a 128-byte buffer, support of 115.2K baud serial data rate and byte swapping. SST Woodhead Connectivity, Waterloo, ON.  www.rsleads.com/302df-111

Gearhead
Taking the place of cylindrical output shafts commonly seen on gearboxes associated with low backlash planetary gear drives, a rotating flange output shaft is used with the Type BDB gearhead. Elimination of the long output shaft omits torsional deflection, leaving only gear teeth backlash as a consideration. Minimum backlash on this type is 5- 3- or 1-arc-min. Mijno Precision Gearing, Park Ridge, IL.  www.rsleads.com/302df-112

Rotary encoder
Size 21 RCM21 commutation encoder combines 3-phase brushless motor commutation pulses, 2 data channels (in quadrature) and once-per-revolution reference index pulse in a single optical encoder. One push of the patented slide/lock mechanism aligns, centers and properly gaps the encoder for optimum performance. Resolution varies from 256 to 2048 lines. Renco Encoders Inc, Goleta, CA.  www.rsleads.com/302df-113

Rectifiers
Designed for use on the company’s line of armature-actuated electric brakes, AAB rectifiers now include Quick Set and Quick Set/Release products that reduce brake set time or armature attraction time for specific applications. An optional proving switch monitors the current waveform of the brake coil and signals when the brake is released via a light, buzzer or other alarm device. Stearns Division of Rexnord Corp, Milwaukee, WI.  www.rsleads.com/302df-114

Hysteresis clutches
These permanent magnet hysteresis clutches transmit rotational torque while allowing precise overload slipping. The flexible design allows unlimited torque adjustment while accommodating proper heat dissipation. The hysteresis design eliminates cogging usually associated with permanent magnet devices. Special designs are constructed from stainless steel for wash-down environments. Rimtec Corp, Addison, IL.  www.rsleads.com/302df-115

AS-i master and PLC
The Controller-E high-speed AS-i master and PLC integrated into a compact housing can be used as a gateway to higher-level bus systems or as a stand-alone PLC. It fully supports all AS-i 2.1 specifications, provides detailed diagnostics on its integrated backlit LCD and features 1 MB total memory with 128K words devoted to program memory. ifm effector inc, Exton, PA.  www.rsleads.com/302df-116

Programmable controller
The MR13 3-channel multi-input, multi-range user-programmable controller can be used as a 3-zone controller, follower controller or cascade control. Incorporating Expert PID, the unit suppresses hunting caused by overshoot or process disturbance. An optional 9-step option is available for applications where ramp and hold programming is required. Vespo Marketing Associates Inc, Thomson Ridge, NY.  www.rsleads.com/302df-117

Lead screws
Combining drive and support/guidance components in a single compact coaxial design, the ScrewRail saves space while eliminating the need for external rail-to-screw alignment. The system is comprised of a precision rolled lead screw supported by sealed bearings and contained within a concentric steel guide rail that drives and integrated nut/bushing. When mounted vertically, the unit supports Z-theta motion. Kerk Motion Products, Hollis, NH.  www.rsleads.com/302df-119
