AGV Magnetic Tape Technical Data Sheet & Specifications
This agv magnetic tape spec sheet defines magnetic response, dimensions, adhesive behavior, and sensor interface under stated test conditions. It applies to floor-installed magnetic guide tape for AGV navigation on epoxy, sealed concrete, or industrial tile. Values are typical, reference, or project-confirmed data. Final route acceptance requires the actual AGV sensor, intended floor, and a representative trial to confirm magnetic detection, adhesion, and route stability.
Route Qualification Boundary for Magnetic Guide Tape
This record covers flexible magnetic guide tape for factory-floor AGV navigation, focusing on magnetic construction, dimensions, adhesive performance, sensor conditions, and project qualification.
It does not define AGV control logic or facility traffic design. General roll formats remain with the magnetic guide tape for AGV product record; this record concentrates on qualification.
What the Tape Stack Contributes to Sensor Reading
A typical construction combines flexible magnetic rubber, controlled magnetization, a protective surface, and pressure-sensitive adhesive. Magnetization direction and exposed polarity affect the sensor field; surface condition and adhesive contact influence route stability.
What Must Be Declared
Item | Typical Value / Reference Range | Test Method or Condition | Notes |
Magnetic material | Flexible magnetic rubber | Construction record | Separate unlike compounds by grade. |
Magnetization / polarity | Single-pole or specified | Defined polarity check | Record direction and pole. |
Total thickness | 1.0 - 1.5 mm current reference | Multi-point gauge | Tolerance is project-confirmed. |
Width | 30 mm / 50 mm current reference | Finished-width measurement | Validate other widths with the sensor. |
Magnetic flux density | Project-confirmed value | Gaussmeter/teslameter at stated distance | Record probe direction, polarity, temperature. |
Peel adhesion | Project-confirmed value | 90 or 180 degree peel; state substrate, dwell | Confirm on the actual floor. |
Service temperature | -10 C to 60 C current reference | Conditioning and recheck | Not the application temperature. |
Measurement Conditions Come Before the Number
Magnetic field strength cannot be compared without the same distance and probe geometry. Record instrument, probe orientation, N-pole or S-pole exposure, tape distance, and temperature.
Test Item | What It Checks | Suggested Method or Reference | Why It Matters | When To Request It |
Magnetic field | Flux density at stated distance | Calibrated gaussmeter/teslameter | Reading changes with distance | Grade approval or sensor change. |
Polarity | Exposed pole and direction | Polarity map or equivalent | Polarity changes response | New batch or splice. |
Peel adhesion | Bond to defined substrate | ASTM D3330 or equivalent | Checks edge-removal behavior | New adhesive or floor coating. |
Sensor response | Tape read by actual AGV sensor | Actual height, speed, orientation | Confirms compatibility | Before route release. |
Which Values Can Be Compared - and Which Cannot
Do not compare surface flux with a reading taken at sensor operating height. Peel adhesion does not represent initial tack or holding force, and thickness does not prove magnetic strength. Service temperature should also remain separate from adhesive application temperature.
For visual lane marking rather than magnetic navigation, heavy duty floor marking tape should be assessed separately; abrasion and adhesion data do not establish magnetic guidance.
Floor-Sensor Fit Under Real Installation Conditions
Smooth epoxy, sealed concrete, and industrial tile are practical starting surfaces. Painted or coated floors require a sound coating; dust, oil, moisture, rough texture, or low-energy surfaces need separate trials.
Nearby steel, motors, magnetized components, or adjacent tracks can alter the field at the magnetic guidance sensor. For facility-wide interaction with forklifts, pedestrians, pallet staging, and work-cell boundaries, review the warehouse and factory floor safety marking guidance separately.
Route Trial at 24 h, 72 h, and 7 Days
Install a representative section using the planned cleaning, pressure, sensor height, speed, load, and route geometry. Record temperature, humidity, coating condition, and settings.
At 24 h, inspect edge contact, bubbles, and sensor reading. At 72 h, check edge lifting, joint movement, adhesive trace, and route stability. At 7 days, inspect wheel abrasion, sensor dropout, residue, surface shadow, gloss change, and tape tearing. Extend the trial if normal traffic is not represented.
Failure Signals When One Control Drifts
Data Point | If Too Low | If Too High | Risk in Application | Check Before Full Use |
Magnetic field at sensor height | Weak signal | Outside sensor range | Route hunting or dropout | Test sensor at operating height. |
Peel adhesion | Edge lifting | Hard removal | Dirt ingress, adhesive trace, coating stress | 24 h / 72 h / 7 day trial. |
Shear / holding force | Lateral creep | Limited conformability | Joint shift in turns | Loaded traffic trial. |
Ferrous interference | Signal distortion | Severe misread | Dropout near steel or motors | Test with nearby equipment. |
Roll History Can Change the Starting Condition
Store rolls in original packaging in a dry, shaded area within project-confirmed limits. Heat, sunlight, humidity, roll pressure, storage time, vibration, damaged wrapping, or contamination can alter roll shape or adhesive condition. Recheck magnetic and bond performance after abnormal storage or transport.
FAQ
Why must magnetic measurement distance be stated?
Because the field available to the sensor changes with distance. Surface and operating-height values are not equivalent.
Can two tapes with the same surface flux behave differently?
Yes. Magnetization, polarity, sensor height, floor condition, speed, and interference can change sensor response.
Why test floor adhesion and sensor response together?
A strong field cannot compensate for weak adhesion, route movement, coating failure, or incorrect sensor height.
Does sensor operating height belong in the tape qualification record?
Yes. Sensor height changes the magnetic field presented to the guidance sensor, so the qualified height or operating window should be recorded with the tape, sensor, speed, and route-test conditions.
