TECHNICAL REFERENCE MANUAL
3. Introduction
DS TACHO 2 is a remote optical LED sensor. It has a visible red LED light source and green LED on-target
indicator. The red LED light source acts as the aiming device during setup and can accurately measure
speeds from 1 up to 250000 RPM from a distance of up to 1 meter with a maximum offset angle of 45
degrees from the rotating object. The sensor is housed in a threaded stainless-steel tube and supplied
with a 90-degree mounting bracket and a 2.5 meter shielded cable.
Common usage of the sensor is in a wide range of general purpose applications in relatively clean
environments.

5. Operating instructions
The remote optical sensor is capable of detecting a reflected pulse from a target consisting of reflective
tape at distances of up to 1 meter from the rotating object and angles up to 45 degrees.
For most applications, a 12-mm square piece of reflective tape should be applied to a clean area on the
rotating object. The sensor should be optically aligned to illuminate the on-target indicator once per
revolution. The sensor must be mounted steady to obtain accurate measurement. The optical sensor
must be placed at a slight angle (15 degrees recommended) from perpendicular, so that the sensor will
receive only pulses from the reflective marker.
The optical sensor must be at least 25 mm from the reflective target to avoid false triggering. The green
LED on-target indicator will blink at the input frequency rate when the sensor is properly aimed.
NOTE : The green LED On-Target Indicator will blink on and off at slow speeds and
remain on steady at high speeds.

6. Set up in DEWESoft
Connect the sensor to the counter input (ACC+, STG+, Multi, …) and enter the counter setup.
Under the Basic application select Sensor (encoder, CDM, tacho…) mode. From the dropdown menu
select the Tacho (Digital) as a sensor type. It depends on the connection of the sensor which signal is
selected as Signal input (CNT_IN1 or CNT_IN0). After selecting all the mentioned parameters, you can
immediately see the angle and the frequency of rotation.

7. Measurement
Once the sensor is properly connected and defined in DEWESoft, it can be used for frequency
measurements (for example: order tracking, balancing, basic RPM measurements, …).
Example: in the order tracking setup you can directly select the tacho as a frequency channel.
The lowest detectable frequency for the counter input on the DEWE-43 / SIRIUS is 5 Hz, therefore if you
have 1 pulse/revolution, the lowest RPM is 300.
