* Be sure to turn off power before disconnecting or connecting sensors.
Photosensor types
* In general, photo sensors can be divided into four types: the interrupt type (U-shaped), the
actuator type, the reflection type, and the transmission type.
Magnetic sensor types
* Some magnetic sensors use Hall ICs, while others use magnetic reed switches.
Switch types
* Microswitches use either N.O. (Normally Open) contact or N.C. (Normally Closed) contact.
* The N.O. contact closes when the switch actuator is pressed.
* The N.C. contact opens when the switch actuator is pressed.
