## Description
The SUCO 0184-458031-SS is a diaphragm-based vacuum pressure switch designed for industrial pneumatic and hydraulic monitoring applications. Engineered within the 0184 series, this component features a zinc-plated steel body with a G 1/4" BSP pressure port, ensuring robust mechanical integration in systems requiring precise vacuum level detection. The switch operates within a pressure range of 1 bar to 10 bar and is capable of handling a maximum system pressure of 10 bar. It utilizes a factory-calibrated hysteresis of 10% to 30% to prevent contact chatter in fluctuating pressure environments.
Electrically, the device is configured as a Single Pole Double Throw (SPDT) switch, providing both normally open and normally closed contact options to facilitate versatile control logic. It is rated for a maximum switching voltage of 250 VAC and a switching current of 4 A, with a DC resistive load capacity of 24 V/4 A. The electrical interface is managed via an integrated DIN connector, which contributes to an IP65 ingress protection rating. Designed for reliability in demanding environments, the switch maintains operational stability across a temperature range of -30°C to +100°C and exhibits high resistance to vibration (10g at 5-200 Hz) and mechanical shock (294 m/s²).

Please note that all switches can be set & adjusted via the central turning screw. N.B. When using oxygen, the relating accident prevention regulations are to be observed. Above that, we recommend not to exceed a maximum operational pressure of 10 bar. Piston pressure switches are not suited for gaseous media, especially not for the use of oxygen. 1) Static pressure, dynamic pressures should be 30 to 50% lower. These values refer to the hydraulic or pneumatic part of the pressure switch.
