Quadrature Encoder

The ADAM-5081 high-speed quadrature encoder and counter module from the Industrial Automation Group of Advantech (Cincinnati, OH) provides isolation of 2,500VDC, a high-speed frequency mode (5 Hz to 1 MHz), and a counter code at 1 MHz. An advanced digital filter eliminates noise and interference.

Load Actuator

The MX Series linear actuator from Pacific Bearing Company (Rockford, IL) comes in belt-driven vertical and horizontal configurations, and in a choice of sizes. The actuator has large cam rollers to carry high loads at greater speeds. It also has a long stroke length to accommodate tasks requiring movement over further distances.

Linear Position Sensor

The A40-HR 20P linear position and velocity sensor from Visi-Trak (Charlottesville, VA) provides control resolution exceeding 0.001 in. at 200 inches per second. The auto-calibrating sensor can sense any stroke length, suiting it for hydraulic and pneumatic cylinders or any linear actuator requiring high speed and precision. The sensor comprises a transducer paired with an encoded rod, housed in a cylindrical enclosure measuring 0.656 in. diameter × 1.75 in. long. An anti-aliasing encoder interface allows precise sampling at high speeds without contact between the rod and the transducer.

Speed Regulator

The MINI-K® model Kinechek® speed regulator from Deschner Corp. (Santa Ana, CA) is available in ½, 1, 1¼, and 1½ inch stroke lengths with a maximum capacity of 400 lbs. There are no sliding seals, and no heavy springs to make the plunger bind or jerk, so the regulators provide smooth, consistent control of moving devices, whether the force is 2-½ or 1200 lbs.

Servo Drive

The Bassoon servo drive from Elmo Motion Control (Westford, MA) has an absolute encoder and delivers up to 1.9 kW of continuous power, or 3.8 kW peak. The fully programmable drive can operate in position, velocity, and current modes and controls brushed dc, brushless ac, and linear motors. The drive is easily set up via the CANopen protocol DS-301 and DSP-402. It measures 4.13 × 1.73 × 3 in.

Conveyor Brake

Designed for decline conveyors with a fail-safe requirement, the EC100 RollerDrive from Interroll Corp. (Wilmington, NC) has a mechanical rotor locking break that prevents drifting on inclines while ensuring smooth operation, low-noise emission, and an extended operating lifetime. The EC100B brake mechanism requires no special control, as two wires are simply attached to the main power bus. The new technology comprises a mechanical rotor-locking break, which is spring-loaded and does only cycle with main power. The brake does not cycle with each start and stop of the conveyor. As long as the power bus is on, the magnetic force created by the solenoid keeps the rotor free.
