Industrial SI30-DC4 Proximity Sensor Proximity Sensor

AECO SI30-DC4 PNP NO 120C TB is a tubular inductive proximity sensor with a 30 mm diameter and a 23 mm long body, designed for metal-detection tasks in industrial equipment. It delivers a normally-open (PNP) output and switches when a metal target enters its 4 mm nominal sensing distance. The sensor operates on a supply range of 10–30 V DC and is wired via a 2 m PVC/PVC cable carrying three conductors of 0.35 mm², which supports straightforward connection to PLCs or automation controllers. Its compact tubular housing enables mounting in restricted spaces, while the 30 mm form factor offers reliable targeting in conveyor lines, presses, or tooling setups where space is at a premium. The TB variant designation indicates a high-temperature construction within the SI30-DC4 family, aligning with industrial environments that challenge performance and longevity. With a PNP NO configuration, the device sources current to the connected control circuit when a metal target is present, providing a simple, positive-switching interface for standard industrial input modules. This sensor model is commonly stocked by AECO and compatible with other SI30-DC4 PNP NO TB components in similar automation applications, making it suitable for retrofit projects or new installations that require tubular proximity sensing in metal-processing or fabrication lines.
