It also can be programmed based on a specific application’s requirements, including travel range, braking requirements, and trigger features.

The CNT2440 autoclavable controller is ideal for those seeking a one-of-a-kind sterilizable motor and sterilizable controller package, being especially well-suited to drive battery-powered surgical hand tools.
