            "description": "#### **KUS Hall Effect Sensor RPM Transducer / Holzer Transducer – Digital Signal Precision for the Cockpit & Vehicle Electrical System**\n\nMaximum precision from the very first revolution! The original **KUS Hall Effect Speed Sensor (also known as the Holzer sensor)** uses the physical Hall effect to measure changes in the magnetic field on rotating shafts or gears. Unlike purely passive magnetic sensors, this active sensor delivers a crystal-clear, digital square-wave signal. This ensures absolutely jitter-free transmission—even at extremely low RPMs or when moving through the water at minimal speed.\n\nIt is the top choice for modern digital instrument clusters, onboard computers, and NMEA converter boxes that require a clear digital signal for error-free data processing.\n\n---\n\n#### 🔌 **Active Technology – Please Note Installation Instructions:**\n\nSince Hall sensors (Holzer sensors) contain electronic semiconductors, they require their own power supply (3-wire connection: positive, ground, signal), unlike passive sensors. Please select the appropriate shaft length for your engine from the menu above.\n\n---\n\n#### **Advantages & Technical Highlights at a Glance:**\n\n- **Digital square-wave signal:** No signal distortion or susceptibility to interference over long cable runs from the engine compartment up to the control station.\n- **Measurement starting at 0 rpm:** Unlike inductive transducers, it operates independently of speed—delivering a perfect signal even at extremely slow rotation speeds.\n- **V4A stainless steel construction:** Housing made of high-strength **AISI 316 stainless steel**. Absolutely resistant to engine oils, fuels, and aggressive saltwater.\n- **Fully encapsulated to IP67:** Completely dustproof and waterproof, designed to withstand the harshest mechanical vibrations during continuous operation.\n\n---\n\n#### **Technical Data (Specifications):**\n\n**Property**\n**Specification / Value**\n\n**Manufacturer / Brand**\nKUS\n\n**Technology Type**\nActive Hall-Effect Sensor (Holzer Sensor)\n\n**Signal Type**\nDigital square-wave signal\n\n**Operating Voltage**\n12 V / 24 V DC compatible\n\n**Protection Class**\nIP67 (completely water- and dust-tight encapsulation)",
