Cylindrical linear motors were some of the first commercially available linear motors, with the only point of support at the ends of a ________ rod

U-channel linear motors have two parallel magnet tracks facing each other, creating a ________ shape

Flat linear motors feature a flat track below a ________

Linear motors are not necessarily ________

The cost of ______ sensor systems is presently higher than that of conventional systems, but when the cost of maintenance, ease of programming, ease of adding new sensors is taken into account, the long-term cost of ______ sensor systems is less.

Disadvantages of smart sensor: If upgrading to smart sensors, care has to be taken when mixing old devices with new sensors, since they may not be ________.

If a bus wire fails, the total system is down, which is not the case with discrete wiring. However, with discrete wiring, if one sensor connection fails, it may be necessary to shut the system down. The problem of bus wire failure can be alleviated by the use of a redundant backup ________.

An actuator is a device that produces a motion by converting energy and control signals going into the system. The motion it produces can be either rotary or ________.

Linear actuators produce ________ motion. This means that linear actuators can move forward or backwards on a set linear plane.

Rotary actuators produce ________ motion, meaning that the actuator revolves on a circular plane.
