Nook Industries (Cleveland, OH) has released the Nook Sensor System™ that provides position control for translating screw jack systems. Designed for the ActionJac™ inch and metric translating screw jacks, the system features repeatability to ±.004" and a cylindrical aluminum stem cover that provides a housing shroud for select position and travel limit sensors. The sensors on the system are manufactured using a polypropylene over-molding technology that allows the sensor to be sealed into small sizes. An unlimited number of sensors can be added. The system includes a custom adapter, plug, and 10-30 VDC sensors.
