Heavy Duty Digital Length Meter Counter With Smooth Rolling 20 Mm Polyurethane Measure Wheel Built Tough Tracking Rig For Feet Meters Yards And Inches Hassle Free Readout And Relay Control
✔️ 6 digit red display relays NPN PNP signal AC power inputs
This tough digital box measures linear distance by counting wheel rotations while showing results instantly on a bright LED panel. It works great in textile mills or print shops where knowing exact roll length matters all the time. Workers trust this gadget to keep cloth and wires measured right through busy shifts.
✅ Double row six-digit readout tracks up to 999999 units ✅ Reversible sensing handles forward and backward motion tracking ✅ Built in double relay outputs trigger preset alarms easily ✅ Photoelectric encoder provides stable precision readings ✅ Memory keeps your last count safe during temporary shutdowns ✅ Accepts wide input voltage range for flexible plant setup
💡 How does a digital length counter improve track record accuracy? Moving from manual tapes to these boxes is way handier and stops guesswork during heavy shifts. Here is why buyers love them. - Reversible photoelectric sensors catch direction changes fast without wearing out like old metal gears ever could - Handy relay hooks let you tie the unit straight into cutoff switches so production stops exactly when needed - Built memory saves your numbers safely so nobody loses count if the shop power flickers for a split second - NPN and PNP compatibility handles almost any encoder signal you throw at the input ports
