## Description
The SUCO 0184-46103-1-012 is a high-performance diaphragm-type vacuum and pressure switch designed for industrial monitoring and control applications. Engineered with a robust zinc-plated steel body, this component features a G 1/4" BSP pressure port and is rated for an operating pressure range of 10 bar to 100 bar. The unit utilizes an SPDT (single-pole, double-throw) contact configuration, providing versatile changeover switching capabilities for both AC and DC control circuits. It is electrically rated for a maximum switching voltage of 250 VAC and a resistive switching current of 4 A, ensuring compatibility with standard industrial automation interfaces.
This pressure switch is designed for reliability in harsh environments, offering an IP65 ingress protection rating when utilized with the integrated DIN connector. The internal diaphragm mechanism is optimized for a wide operating temperature range of -30°C to +100°C, making it suitable for hydraulic, pneumatic, and fluid power systems. The 0184 series allows for field-adjustable hysteresis, typically ranging from 10% to 30%, which can be calibrated via a central adjustment screw to meet specific system setpoint requirements. With a mechanical life expectancy of up to 10^6 operations, this sensor is engineered for long-term stability in demanding process control and monitoring environments.
