Students read an introduction to the Metal Oxide Semiconductor Field Effect Transistor. They also examine its enhancement mode.

In this interactive object, learners demonstrate the proper tightening sequence for mechanically joining two mating surfaces.

Students read about the ENTRY, INS, and DEL keys and view a demonstration of how to edit and insert characters and recall previous entries.

Learners study the descriptions of the three words in a PLC timer: EN, DN, and TT. They then test their knowledge in a brief quiz.

Learners study the method of using more than one track and quadrature modes to improve the resolution of an optical encoder. A brief quiz completes the activity.

In this animated object, learners examine the two types of optical encoders used in automation applications: incremental and absolute. A brief quiz completes the activity.

Learners examine the internal components of an optical encoder used in automated manufacturing applications. A brief quiz completes the animated activity.

Learners observe how an optical pyrometer is used to take temperature measurements without making physical contact with the object being measured.

This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
