Unlike traditional position sensors that use mechanical linkages and moving parts, the SmartStick uses non-contact digital sensing technology — eliminating wear, reducing maintenance, and providing more reliable position feedback over time.\u003c\/p\u003e\u003cp\u003eWith fully potted electronics for corrosion resistance, integrated electronics in the sensor body for clean cable routing, and 35 feet of trimmable cable, the DK4220 is designed for straightforward installation without splices or external mounting hardware.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Contact Sensing\u003c\/strong\u003e — No moving parts to wear out; more reliable long-term than mechanical linkage sensors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Cylinder Mount\u003c\/strong\u003e — Mounts directly to SeaStar HC5345 and HC5358 outboard front-mount cylinders; no external linkages or brackets required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast, Convenient Installation\u003c\/strong\u003e — No linkages or external parts to mount; significantly simpler than traditional position sensors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFully Potted Electrical Components\u003c\/strong\u003e — Sealed against corrosion for reliable performance in marine environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegrated Electronics\u003c\/strong\u003e — Electronics built into the sensor body for clean cable routing without splices\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e35’ Trimmable Cable\u003c\/strong\u003e — Cable can be cut to any length needed for your installation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDigital EMI Immunity\u003c\/strong\u003e — Digital electronics are more resistant to electromagnetic interference than analog sensors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e DK4220 | SKU: 861-DK4220\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatible Applications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSeaStar Solutions HC5345 outboard front-mount hydraulic steering cylinder\u003c\/li\u003e\n\u003cli\u003eSeaStar Solutions HC5358 outboard front-mount hydraulic steering cylinder\u003c\/li\u003e\n\u003cli\u003eOutboard hydraulic steering systems requiring rudder position feedback for autopilot, digital switching, or helm display integration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Verify compatibility with your specific autopilot or display system before ordering — the DK4220 is a sensor and gauge kit; confirm the gauge output is compatible with your electronics\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eParts Desk Insights\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eBest Use Case:\u003c\/strong\u003e The DK4220 SmartStick is the right sensor when you’re adding rudder position feedback to a SeaStar HC5345 or HC5358 hydraulic steering system — most commonly for autopilot integration, where the autopilot computer needs to know the current rudder angle to steer accurately. The non-contact design is a meaningful advantage over older mechanical linkage sensors: there are no pivot points to corrode or wear, and the digital output is more immune to the EMI that can cause erratic readings on boats with multiple electronics. The 35’ cable with trim-to-length flexibility makes routing straightforward on most boat layouts without needing extension cables or splices. Confirm that your autopilot or display system accepts the DK4220’s output signal before ordering — not all autopilot systems are compatible with every rudder feedback sensor.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51250852855844,"sku":"861-DK4220","price":745.59,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/861-DK4220.jpg?v=1786511111","url":"https:\/\/marisolmarine.com\/products\/seastar-dk4220-smartstick-sensor-and-gauge-kit-861-dk4220","provider":"Marisol Marine Company","version":"1.0","type":"link"}
