Why Choose the EMAS SCM30NP1PSX Capacitive Sensor?
The EMAS SCM30NP1PSX is an industrial M30 capacitive proximity sensor designed for reliable non-contact detection in automation, machinery and process-control applications. As part of the EMAS SCM series, it combines an adjustable 3–15 mm sensing distance with a PNP normally open output, non-flush construction and a convenient M12 connector.
Capacitive sensing technology allows the SCM30NP1PSX to detect changes in capacitance caused by a target entering its sensing field. Unlike inductive proximity sensors, capacitive sensors can detect suitable metallic and non-metallic materials, making them useful for applications involving plastics, glass, powders, granules and liquids as well as conventional solid objects.
The SCM30NP1PSX operates from a 12–30 V DC supply and provides a PNP normally open (PNP-NO) output with a maximum load current of 200 mA. Its non-flush M30 plastic cylindrical housing, M12 connector, IP65 protection and integrated electrical protection features make it a practical sensor for demanding industrial automation installations.

Reliable Capacitive Detection for Industrial Automation
Capacitive proximity sensors detect targets by monitoring changes in the electrical field generated at the sensing face. Because their operation is based on capacitance rather than magnetic properties, they can detect a broader range of materials than conventional inductive proximity sensors, including many plastics, glass products, powders, granules and liquids.
The EMAS SCM30NP1PSX combines this versatile sensing principle with a 3–15 mm detection range, PNP-NO switching and a non-flush M30 plastic housing. Its M12 connection makes installation and sensor replacement straightforward, while solid-state operation eliminates mechanical sensing contacts that could otherwise be subject to friction and wear.
Typical Applications
- Industrial machinery and factory automation.
- Non-contact object presence detection.
- Plastic and non-metallic component detection.
- Level detection of suitable liquids, powders and bulk materials.
- Packaging and production machinery.
- Conveyors and material handling equipment.
- Process automation and monitoring systems.
- OEM machinery and PLC-controlled equipment.
