SUCO 0184 Series Diaphragm Pressure Switch

The SUCO 0184 Series Diaphragm Pressure Switch provides precise and reliable pressure control for demanding industrial applications. Its robust construction, featuring a zinc-plated steel body, ensures durability in challenging environments. The unit utilises a sensitive diaphragm system with multiple seal material options—nitrile, EPDM, or viton—to guarantee a reliable seal and compatibility with a wide range of media.

This switch is equipped with a powerful 4A-rated SPDT (Single Pole, Double Throw) changeover contact, allowing it to control electrical circuits based on pressure thresholds. It features a built-in DIN connector for secure and straightforward electrical installation, offering an IP65-rated housing for effective protection against dust and water ingress. With an operational lifespan of 10⁶ cycles at 50 bar pressure, it is engineered for long-term, dependable service.

Key Specifications & Applications

The switch is available across a comprehensive pressure range, from sensitive low-pressure applications (0.3–1.5 bar) up to robust industrial settings (10–100 bar), with an impressive overpressure capability of up to 300 bar. Its compact dimensions make it suitable for integration into space-constrained assemblies. This versatile component is ideal for pressure sensing in pneumatic systems, instrumentation panels, process control, and various industrial machinery where accurate pressure monitoring and circuit switching are critical.
