Consider the following three types of photoelectric object counters (or object detectors or limit switches):

1. Through (opposed) type

2. Reflective (reflex) type

3. Diffuse (proximity, interceptive) type

Classify these devices into long-range (up to several meters), intermediate range (up to 1 m), and short-range (up to a fraction of a meter) detection.
