Connector and LED Identification
Status LED Flashing Patterns
The MTS160 has two RGB LEDs located behind the arrow-shaped window. These LEDs indicate the operating state of the sensor and the presence of tracks, markers, or point sources within the sensing range.
| LED Status | Track Detect | Left Marker | Right Marker | Description |
|---|---|---|---|---|
 Steady Blue | No | No | No | The sensor is powered and ready, but no track, markers, or point sources are detected. |
 Steady Green | Yes | No | No | The sensor is detecting a magnetic track, with no markers detected alongside it. |
 Steady Yellow-Green | Yes | Yes | No | The sensor is detecting a magnetic track and a marker on the left side. The yellow LED indicates the side on which the marker is detected. |
 Steady Green-Yellow | Yes | No | Yes | The sensor is detecting a magnetic track and a marker on the right side. The yellow LED indicates the side on which the marker is detected. |
 Steady Yellow | Yes | Yes | Yes | The sensor is detecting a magnetic track with markers on both sides. |
 Steady Cyan-Blue | No | Yes | No | The sensor is detecting a left-side marker only, with no track present. The cyan LED indicates the side on which the marker is detected. |
 Steady Blue-Cyan | No | No | Yes | The sensor is detecting a right-side marker only, with no track present. The cyan LED indicates the side on which the marker is detected. |
 Steady Cyan | No | Yes | Yes | The sensor is detecting markers on both sides, with no track present. |
 Steady Red | No | No | No | The sensor is non-functional or has encountered a critical fault. |
 Steady Purple | — | Sensor is not calibrated. Perform zero-calibration with the Naviq utility. | ||
 Flashing Red | Pattern Dependent | Alternating red and any of the color patterns listed in this table indicates that the sensor failed one or more internal self-tests. It may still output data, but robot operation should be stopped, and the sensor serviced. | ||
Suitable Magnetic Materials
The sensor is designed for use with magnetic tape that has unipolar magnetization, with either the North or South pole on the top surface. It supports different tape widths and operating heights within the specified sensing range.
WARNING
The sensor will not work with materials that use alternating-pole magnetization.
Figure 3 shows examples of magnetic components compatible with the sensor. The graph above each example illustrates the relative field strength and polarity profile.
Tracking Tape
Use magnetic tape to define the path for the robot to follow. Tape is commonly available in narrow (25 mm) and wide (50 mm) versions. Wider tape generally produces a stronger magnetic field and has higher adhesion to the floor. The narrow tapes are more economical.
Square Profile
For high-traffic areas or harsh environments, a magnetic square profile embedded in the floor may provide better durability.
Position Markers
Position markers are made from magnetic material with polarity opposite to that of the main tracking tape. They are used to provide location reference points along the track.
Point Source Disks
For precise end-position alignment, 20 mm magnetic disks can be used as localized magnetic point sources. These allow the sensor to determine X and Y position for fine alignment. Point source disks are available from Naviq.
Mechanical Dimensions
All dimensions are in millimeters.
