Prox is short for which device?

Explanation:
The shorthand prox refers to proximity, specifically a proximity sensor or proximity switch. These devices detect the presence of nearby objects without physical contact, using technologies like inductive, capacitive, or optical sensing. In many automation panels and diagrams, “prox” is used to label a proximity sensor because its job is to sense something entering its sensing range and change an output state accordingly. It isn’t a pressure transducer (which measures pressure), a programmable logic controller (which processes logic), or a proportional valve (which modulates flow).
