Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.

In this animated activity, learners examine how to change the gain of an optical sensor to overcome environmental conditions and distance.

In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.

In this animated object, learners examine the switch settings for the on-delay, off-delay, and one-shot timing functions of an optical sensor. A brief quiz completes the activity.

The learner tests his/her ability to set up the optical comparator edge detector using a virtual simulation of the machine.

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

Students read how to set up the optical comparator edge detector in this interactive learning object.

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

Students review the functions of the keys on the Starrett HB400 Optical Comparator controller.

In this interactive learning object, learners read how to compensate for a part not mounted perfectly parallel to the machine axis.

This animated lesson shows the operation and characteristics of thru-beam optical sensors.

The operation and characteristics of an absolute optical encoder used in automation applications are presented.
