The HYPSEN HFS03-60LAB-M84 is a metal-bodied fork sensor with a 3 mm × 60 mm slot and a self-teach function.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA fork-type photoelectric label sensor for labelling and packaging machines. The label web runs through the 3 mm slot; the sensor sees the change in translucency at each label edge and outputs a pulse, so the applicator knows exactly where one label ends and the next begins.\n\nIt self-teaches: run a short length of web through, press teach, and it sets its own threshold — no potentiometer hunting when you change label stock. Light-on and dark-on are both selectable, and the same 4-pin M8 connector carries NPN and PNP outputs, so it drops into most existing controllers without rewiring the input card.\n\nThe 60 mm slot depth clears wide webs, and the metal housing survives the knocks that plastic fork sensors do not.\u003c\/p\u003e\u003ch2\u003eWhat can you use it for?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLabel gap detection on rotary and linear self-adhesive labelling machines\u003c\/li\u003e\n\u003cli\u003eRegistration mark detection on flow wrappers, bag makers and pouch fillers\u003c\/li\u003e\n\u003cli\u003eBacking-web presence and label-missing alarms on print-and-apply heads\u003c\/li\u003e\n\u003cli\u003eRetrofit replacement for worn GS61, FC-2110, SR21, WF2 and 6.2 series label sensors\u003c\/li\u003e\n\u003cli\u003eWeb position sensing on small converting, slitting and rewinding machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho is it for?\u003c\/h2\u003e\u003cp\u003ePackaging machine builders, labelling line maintenance technicians and automation integrators who need a self-teaching label sensor that drops into an existing NPN or PNP input without rewiring.\u003c\/p\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eControllers: any PLC, motion controller or labelling-head board with a 12–24 V DC sinking (NPN) or sourcing (PNP) digital input\u003c\/li\u003e\n\u003cli\u003eLabels: self-adhesive paper and film labels, including semi-transparent stock, on a backing web\u003c\/li\u003e\n\u003cli\u003eElectrical: 12–24 V DC supply, 100 mA maximum load; both NPN and PNP outputs are present on the same 4-pin M8 connector\u003c\/li\u003e\n\u003cli\u003eReplaces: GS61, 6.2, FC-2110, SR21 and WF2 label sensors of the same fork format\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003ctd\u003eHYPSEN HFS03-60LAB-M84\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eFork (slot) photoelectric label \/ mark sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSlot\u003c\/th\u003e\n\u003ctd\u003e3 mm gap × 60 mm depth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSupply voltage\u003c\/th\u003e\n\u003ctd\u003e12–24 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOutput\u003c\/th\u003e\n\u003ctd\u003eNPN and PNP both available on the same 4-pin connector, 100 mA load\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWiring\u003c\/th\u003e\n\u003ctd\u003e1 brown +, 2 white PNP, 3 blue −, 4 black NPN\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSwitching mode\u003c\/th\u003e\n\u003ctd\u003eLight-on \/ dark-on selectable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTeach\u003c\/th\u003e\n\u003ctd\u003eSelf-learning — one touch re-teach on label changeover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDetects\u003c\/th\u003e\n\u003ctd\u003eSelf-adhesive labels and semi-transparent labels on a backing web\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHousing\u003c\/th\u003e\n\u003ctd\u003eMetal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eConnector\u003c\/th\u003e\n\u003ctd\u003eM8 4-pin, supplied with 2 m cable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMarking\u003c\/th\u003e\n\u003ctd\u003eCE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReplaces\u003c\/th\u003e\n\u003ctd\u003eGS61 · 6.2 · FC-2110 · SR21 · WF2 label sensors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat's in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\n\u003cstrong\u003eSensor + 2 m M8 cable (set):\u003c\/strong\u003e 1 × HFS03-60LAB-M84 fork sensor, 1 × 2 m M8 4-pin cable\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eShipping and returns\u003c\/h2\u003e\u003cp\u003eShips from our warehouse in Singapore with tracking.

The emitter shines through the backing paper; where a label is present the web is less translucent, so the receiver sees less light. The sensor converts that step change into a digital pulse at each label edge, which the applicator uses to time label dispensing.\u003c\/p\u003e\u003ch3\u003eDo I need to adjust it when I change label stock?\u003c\/h3\u003e\u003cp\u003eNo potentiometer hunting is needed. Run a short length of the new web through the slot and press the teach button; the sensor measures the label and gap levels and sets its own threshold.\u003c\/p\u003e\u003ch3\u003eIs the output NPN or PNP?\u003c\/h3\u003e\u003cp\u003eBoth. Pin 4 (black) is the NPN output and pin 2 (white) is the PNP output, on the same 4-pin M8 connector. Use whichever matches your input card and leave the other unconnected.\u003c\/p\u003e\u003ch3\u003eWill it detect clear or semi-transparent labels?\u003c\/h3\u003e\u003cp\u003eYes, semi-transparent labels are supported — this is the main reason to use a teach-in sensor rather than a fixed-threshold one. Fully clear labels on clear liner are the hardest case; teach on the actual stock and verify before running production.\u003c\/p\u003e\u003ch3\u003eWhat is the slot size?\u003c\/h3\u003e\u003cp\u003eThe fork opening is 3 mm wide and 60 mm deep, so it clears webs up to 60 mm into the throat and tolerates the flutter of a 3 mm thick path.\u003c\/p\u003e\u003ch3\u003eWhat supply voltage does it need?\u003c\/h3\u003e\u003cp\u003e12–24 V DC, with a maximum switched load of 100 mA. Pin 1 (brown) is positive and pin 3 (blue) is negative.\u003c\/p\u003e","brand":"Glunova Biotech","offers":[{"title":"Sensor + 2 m M8 cable (set)","offer_id":50824102805743,"sku":"HFS03-60LAB-M84-SET","price":192.0,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0821\/5406\/2063\/files\/01_9b1dcc3a-677b-48e7-80c2-8ddfd5b952aa.jpg?v=1789745400","url":"https:\/\/armdojo.com\/products\/hypsen-hfs03-60lab-m84-label-mark-sensor","provider":"ArmDojo","version":"1.0","type":"link"}
