If a spool runs out or a break occurs mid-print, it immediately alerts the mainboard to pause the print job cleanly—preventing ghost printing and head damage.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eHigh-Sensitivity Photoelectric Sensing: \u003c\/strong\u003eUses an infrared optical interrupter to detect filament presence without placing mechanical drag or resistance on the feeding filament.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eAuto-Pause \u0026amp; Resume Support:\u003c\/strong\u003e Instantly triggers an automatic firmware pause whenever filament is depleted or broken, saving the print state for seamless resuming after a spool reload.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eCompact Low-Profile Design:\u003c\/strong\u003e Engineered to mount flush inside the Kobra S1 entry housing without interfering with PTFE tube routing or internal chamber motion.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDirect Plug-and-Play Assembly:\u003c\/strong\u003e Comes pre-soldered with a high-flex lead harness and micro JST header for quick connection to the main motherboard or distribution PCB.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eCompatible Models: Anycubic Kobra S1 \/ Kobra S1 Combo\u003c\/li\u003e\n\t\u003cli\u003eSensor Type: Infrared Photoelectric (Optical) Break Detection\u003c\/li\u003e\n\t\u003cli\u003eOperating Voltage: 3.3V \/ 5V DC\u003c\/li\u003e\n\t\u003cli\u003eSupported Filament Diameter: 1.75 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eMaintenance \u0026amp; Care Tips\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003eKeep Optical Pathway Free of Dust: Fine filament dust or plastic strings can obstruct the infrared beam path.
