Sensors & Controls replacement guide
Identify proximity, photoelectric, pressure, temperature, level, safety, encoder, relay, and control components from exact part numbers and interfaces.
Evidence boundary. Controls are sensitive to revision, firmware, pinout, safety requirements, and output logic. Favor documented successors and exact interface checks over same-function suggestions.
