Rotary actuator. Model RA54-18-000A rotary voice coil actuator is rated at 113 oz-in. continuous stall torque with a 300 oz-in., 10-sec peak torque capability. It is designed for short-stroke, limited angle, high-speed actuations. BEI Kimco Magnetics Division, San Marcos, CA. Free info—Circle 582. www.RSLeads.com/110df-582

Digital servodrives. The DigiFlex (DX) family of servodrives can be used in multi-axis coordinated motion control applications by using CANopen communication protocol. DSP technology is used to close digital current, velocity and position loops to control brushed and brushless servomotors. The position and velocity loop can use encoder, Hall sensor or analog feedback. Supply voltage is 20-80VDC. Advanced Motion Controls, Camarillo, CA. Free info—Circle 577. www.RSLeads.com/110df-577

NEMA 23 motor-driver. Expanding this company’s high-torque integrated motor-driver line, MDrive23 operates in two voltage ranges¾12 to 48 or 24 to 75 VDC. The versatile system is available in various configurations. Intelligent Motion Systems Inc, Marlborough, CT. Free info—Circle 587. www.RSLeads.com/110df-587

Control processor. Designed for the electric industry, the information gathered by the SEL-2701 Ethernet processor can be used for automatic data gathering and control systems such as SCADA, DCS and local HMI. Schweitzer Engineering Laboratories, Pullman, WA. Free info—Circle 584. www.RSLeads.com/110df-584

Couplings. Providing the same torque as steel versions and up to 30% increase in rpm rating, CD-series aluminum single- and double-flex couplings combine high misalignment capacity with high torsional stiffness. Zero-Max, Plymouth, MN. Free info—Circle 585. www.RSLeads.com/110df-585

Conveyor roller. Handling up to 2500 lb palletized loads, the 24VDC BL80 RollerDrive motorized conveyor roller has no external drive components, virtually eliminating conveyor noise. Permanently lubricated 6205ZZ precision bearings provide maintenance-free operation and long service life. Roller tubes are available in either galvanized or stainless steel. Operating temperature is between 40° and 120°F. Interroll Corp, Wilmington, NC. Free info—Circle 586. www.RSLeads.com/110df-586
