ST307350B

The ST307350B unit belongs to the Vickers Hydraulic Accessories series and is produced by Vickers for use in automated hydraulic systems where electrical signaling must coordinate with pressure changes. An EN 175301-803 Type A electrical connection aligns the product with common solenoid plugs, and a Pg11 cable entry secures the incoming lead to prevent strain in mobile machinery. The device accepts 250 V alternating-current control power while also accommodating 24 V direct-current circuits, enabling flexible integration into machine panels. For resistive loads on an AC network it switches up to 5 A, and when driven by DC it carries inductive currents up to 4 A without contact wear.

Installation is completed on a base with two tapped holes, allowing the component to sit rigidly beside valves and filters. A G 1/4 BSPF port connects the hydraulic passage to pilot or sensing lines found in European equipment. The adjustable mechanism lets users set trip points up to 350 bar so pumps or alarms respond at the correct operating pressure, while the standard seal endures static pressures reaching 600 bar to withstand transient spikes. An IP65 enclosure rating blocks dust and low-pressure water jets, ensuring reliable switching on factory floors exposed to oil mist. When the circuit is purely resistive and powered by 24 V DC, the contacts handle up to 5 A, rounding out the electrical capacity of the ST307350B in demanding hydraulic automation tasks.
