The SM2315 is a controller, amplifier, and encoder built into what this company says is a "true" brushless dc servo motor at a price which is competitive with many stepper motor systems. A single microprocessor is said to handle all processing functions, including the PID loop, the trajectory generator, the user program execution, I/O control, and all communications.

MAC? 2000 soft starts are designed for applications where a less sophisticated, lower cost motor control is required. The product is a single unit which can be used for single or two-speed applications, and can be applied through 17 full load amps in 230 and 460V ratings and 12 full load amps for 575V ratings. It also has a small footprint for applications where space is at a premium.

DF-1 differential micrometer positioning heads are reportedly among the smallest commercially available positioning devices. The product is said be mountable to linear slides, or to the company's 99 series subminiature multiaxis positioners by using a finely threaded barrel behind the moving positioning spindle, which has a hardened ball at its end to reduce friction and wear.
