Product Details
🛠️ Typical Specs (General for this Type) FeatureTypical Value Model Family HED 8 piston pressure switch Setpoint Range Adjustable up to ~200 bar Max Operating Pressure ~315 bar (depending on build) Electrical Connection DIN EN 175301‑803 K14 Switch Output Micro switch (NO/NC contacts) Seals NBR (standard) Hydraulic Fluid Mineral‑oil based types HL/HLP etc. Mounting Flange / ISO 4401 subplate pattern Adjustment Screw, knob or internal hex depending on version 📌 How It Works A pressure switch like the HED 8 OH‑20/200K14 sits in a hydraulic line and senses system pressure via a piston mechanism. When pressure reaches your set value (e.g., 200 bar), the internal micro switch changes state — providing a binary electrical signal for control circuits, alarms, PLC inputs, or pump shutdown logic. It does not control flow like a valve — it simply detects pressure and signals an electrical change. It's often used alongside directional valves, proportional valves, pumps, and safety circuits in an integrated hydraulic system. 📦 Common Applications ✔ Hydraulic safety shutdown when pressure is too high✔ Activation of alarms or indicators✔ PLC/logic input for system control✔ Interlock conditions in mobile/hydraulic machinery✔ Process automation pressure monitoring 🧠 Variant Notes Rexroth's HED 8 series has many similar codes for different settings: OH, OA, OP etc. — denote internal switch and adjustment type variations. 20/200K14 indicates the component series and target pressure range (~200 bar) with a K14 connector. Other suffixes (K35 etc.) refer to alternative electrical connectors.
