The ST307150B accessory belongs to the Vickers Hydraulic Accessories series and is produced by Vickers to offer pressure-dependent electrical switching for hydraulic automation. It operates in ambient temperatures from –40 °C to 90 °C so that equipment can run in cold starts or elevated machine rooms. A black painted aluminum housing resists corrosion, while an IP65 ingress rating keeps internal parts protected against dust and low-pressure water jets. The changeover contact supplies two discrete circuit states and supports a maximum ohmic load of 5 A for resistive devices. System pressure up to 500 bar can be applied without compromising the seal, and the brass pressure connection maintains a stable interface under repeated cycling.
An EN 175301-803 Type A connector provides a quick electrical interface, and the unit accepts 250 V AC or 24 V DC to suit control panels running on either mains or low-voltage supplies. Maximum inductive load is 4 A, enabling safe switching of solenoid valves and relays. The M5 × 10 mounting thread fixes the body to brackets or manifolds, and installation torque is limited to 30 Nm to protect the housing. A G 1/4 BSPF port thread ties the switch into common hydraulic lines without adapters, and total weight is 0.5 kg for convenient handling during service.
