Rotary Encoder

Gurley Precision Instruments (Troy, NY) offers the A08/R108 series rotary encoder that provides both incremental (to 4,096 counts) and absolute (up to 12 bits) position information in an 8-mm-diameter package. Available in both a shaft and blind hollow-shaft configuration, the encoder offers several mounting and interface options. Optional temperature range is available from -40 to 85 ºC, and a radial/axial load of 3N. Output options include an RS-422 differential line driver for incremental applications or SSI with gray-code or natural binary where absolute feedback is required.

Magnetic Particle Brakes

Fan-cooled magnetic particle brakes from Placid Industries (Lake Placid, NY) incorporate an electrically powered fan fastened directly to the brake. The fan cools the brake by blowing ambient air over the outside and into the vent holes. The moving air lowers the temperature of the brake and increases heat dissipation ratings. A threaded port accepts compressed air to increase heat dissipation up to 1,900 Watts. Rated brake torque is from 4 to 300 lb-feet. Wide tension ranges are possible since output torque can be varied from 3 to 100% of rated torque. Controlling input DC current varies load torque, and torque is independent of slip RPM. The brakes can be used to produce adjustable soft stops.

Servo Drive

Technosoft (Bevaix, Switzerland) has introduced the ISD860 intelligent drive for motion applications that require embedded intelligence and high servo control. Based on MotionChip™ DSP technology, the device is able to drive 12A continuous and 31A peak currents at a supply voltage ranging from 12 to 72 VDC, with a PWM of 20 kHz frequency. The unit embeds the motion controller, drive, and PLC functionality in one unit. It controls brushless, DC, or linear motors up to 860W continuous/2.2kW peak voltage. It works in single-axis, multiaxis, or standalone configurations, and uses EasyMotion Studio and Technosoft Motion Language for drive setup, tuning, and motion programming, which can be done from a CAN master via PC or PLC, or directly at drive level through its built-in motion controller.

Color Sensors

The Series 4055 color sensors from Contrinex, Old Saybrook, CT, are used for color control and color sorting processes. The sensors feature three teachable color channels with independent 200 mA outputs, which allow for three color tones to be programmed. The teach process offers a choice of five different tolerance levels. Color detection within the operating range of 30 to 40 mm is independent of the target distance. The sensors feature switching frequency to 4 kHz, adjustable pulse delay and stretching, NPN and PNP versions, and 10-bit precision of R, G, and B signals.
