Engineered with a robust 1.4305 stainless steel housing, this component provides reliable performance in environments requiring chemical resistance and structural integrity. The unit features a G 1/4" BSP pressure port and is rated for an operating pressure range of 10 bar to 50 bar. With a mechanical life expectancy of 10⁢ operations at pressures up to 50 bar, it is suitable for long-term deployment in systems where consistent switching cycles are critical. Electrically, the 0184 series utilizes a single-pole double-throw (SPDT) changeover contact configuration, offering versatility for both normally open and normally closed control logic. The switch is rated for a maximum switching voltage of 250 VAC and a maximum switching current of 4 A, with a resistive DC switching capacity of 24 V. The device integrates a DIN connector for secure electrical termination and maintains an IP65 ingress protection rating, ensuring reliable operation in harsh conditions. Operating within a temperature range of -30Β°C to +100Β°C, this pressure switch is optimized for integration into hydraulic and pneumatic control circuits, including sensor signal conditioning and automated monitoring systems. ## Specifications | Parameter | Value | |---|---| | Svhc | No SVHC (16-Jan-2020) | | Deadband Max | - | | Deadband Min | - | | Pressure Type | Vacuum | | Product Range | 0184 Series | | Sensor Mounting | Stud | | Pressure Port Size | 1/4" | | Pressure Port Type | G 1/4" BSP | | Contact Configuration | SPDT | | Electrical Connection | DIN Connector | | Switching Current Max | 4A | | Switching Voltage Max | 250VAC | | Operating Pressure Max | 50bar | | Operating Pressure Min | 10bar | | Pressure Fitting Style | G 1/4" BSP | | Operating Temperature Max | 100Β°C | | Operating Temperature Min | -30Β°C | | Switching Current Dc Resistive | 4A | | Switching Voltage Dc Resistive | 24V | | Transducer Connection / Termination | - | ## Datasheet πŸ“„ [Download PDF](https://novapart.co/datasheet/farnell:7213050/) |83
