As the buffer moves through its range of travel, the relative magnetic field measured by each sensor changes. The \u003cstrong\u003eCompensator\u003c\/strong\u003e PCB processes these signals to provide a combined analog position output, allowing the controller to determine where the buffer is throughout its usable range, not simply whether it has reached an endpoint.\u003c\/p\u003e\n\u003cp\u003eThis continuous feedback allows firmware to distinguish between normal filament movement, increasing or decreasing buffer capacity, center position, and approaching travel limits. Because the sensing system is contactless, there are no mechanical switches in the position-sensing path to actuate or wear.\u003c\/p\u003e\n\u003cp\u003eThe PCB also exposes the individual Hall sensor signals in addition to the combined position output, providing access to the underlying sensor data for calibration, diagnostics, or custom control implementations.\u003c\/p\u003e\n\u003cp\u003eThis makes the \u003cstrong\u003eCompensator\u003c\/strong\u003e suitable for more advanced filament-management applications where knowing the state of the buffer throughout its travel is useful, including multi-color systems, filament feeders, autoloaders, and tool changers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey technical features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDual linear Hall-effect position sensing\u003c\/li\u003e\n\u003cli\u003eSingle moving magnet sensing element\u003c\/li\u003e\n\u003cli\u003eContinuous analog buffer-position output\u003c\/li\u003e\n\u003cli\u003eIndividual raw Hall sensor outputs\u003c\/li\u003e\n\u003cli\u003eContactless position measurement\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDetectable center and travel limits\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eNo mechanical position switches required\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDesigned for closed-loop filament-management systems\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompatible with controller ADC inputs\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Pulsar3D","offers":[{"title":"Single","offer_id":48470898901129,"sku":null,"price":5.99,"currency_code":"USD","in_stock":true},{"title":"5-pack","offer_id":48470898933897,"sku":null,"price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0682\/9031\/4377\/files\/FullSizeRender_79ce6d66-39fe-4ba9-9c5e-57cc72633792.jpg?v=1790016654","url":"https:\/\/pulsar-3d.com\/products\/compensator-linear-buffer-pcb","provider":"Pulsar3D","version":"1.0","type":"link"}
