1.Introduction
The purpose of this document is to give guidelines for installation, use and integration of
the Terabee IND-TOF-1 distance sensor. The user manual includes instructions on the six
modes: setup and operation. For guidelines on sensor connection and usage with a
personal computer, please refer to Terabee IND-TOF-1 Connection to Personal Computer
(Guide).
1.1. About Terabee IND-TOF-1
The Terabee IND-TOF-1 distance sensor offers 12.5 meter detection capabilities with a Field
of View of 2° using Time-of-Flight technology. The rugged IP65 enclosure ensures
dust-proof and water-resistant operation, while the sensor’s compact form-factor (99 g)
allows installation in places not possible with larger & heavier sensors.
Programmable distance thresholds can be set using integrated teach-in buttons to trigger
alarms, detect presence and movement, count objects and more. The sensor provides
proximity notification with a classic NO/NC switching output, while also communicating
calibrated distance data via RS485 (Modbus) interface. Six operating modes enable you to
address a variety of distance sensing and monitoring applications!
Figure 1. Terabee IND-TOF-1
It takes as little as 5 seconds to set up a switching threshold and customized trigger zones
for proximity notification using the integrated teach-in buttons. Multi-color LEDs provide a
visual confirmation of distance threshold breach, sensor power and live data transfer,
making setup easy and intuitive.

3.Mechanical integration
3.1. Mechanical design and mounting
Terabee IND-TOF-1 distance sensor offers an ABS housing and an aluminium backplate
(part of sensor housing) for robust mounting. Figure 3 illustrates external dimensions of
the distance sensor.
Figure 3. External dimensions of Terabee IND-TOF-1
The bottom casing part includes four slots for mounting the sensor using standard M4
screws. The following methods can be used to mount the Terabee IND-TOF-1:
1. Front-panel mount using the long M4 screw slots (Figure 4)
2. Back-panel mount using the 2mm ledge on the front side of the sensor (Figure 5)
The first solution allows for easy surface attachment and rapid evaluation of the sensor.
Depending on the application requirements for connector/cable position, the sensor can
be mounted both horizontally and vertically. The second solution offers the possibility to
mount the sensor behind a surface (e.g. panel), ideally with 2 mm to 3 mm thickness - for a
more integrated look. Please note that mounting components (e.g. screws, nuts, etc.) are
not included in the product packaging.

When choosing a place for installation, please consider the following
recommendations:
●During setup and operation, please make sure that the sensor is not
pointing at a distance longer than the maximum offered range (12.5
meters). Please ensure that a physical object/obstruction (e.g wall) is
covering the sensors entire Field of View, no further than the maximum
range (12.5 meters) of the sensor
●It is recommended to install the sensor min. 70 cm from the
measuring/monitoring objects in your application. Please note that
mounting the sensor with a distance smaller than 70 cm from the
measured object, can affect the sensor absolute accuracy
●Mounting close to sources of heat or strong electromagnetic fields can
decrease the sensing performance
●Do not mount anything directly in front of the sensor
●Within the first meter from the sensor avoid objects with high surface
reflectivity in a cone of approximately ± 45° around the central optical axis
of the sensor
●It is better to avoid having other sources of continuous wave or modulated
IR light close to the sensor
