1. INTRODUCTION
CA109 is designed as a compact and reliable laser distance measuring sensor. The phase
shifting reflectorless technology gives the good accuracy and response time in distance
measuring. It is a compact and customizable LDM sensor.
Features
•Compact and fit for most heavy duties.
•High speed measuring up to 10HZ. (Adjustable)
•Digital output with UART, RS232, or RS485
•Non-contact measuring with low power consumption.
Application
•Robot eyes distance measuring
•Positioning and monitoring of objects
•Security application movement detections
•Level and elevator measuring

2. PRECAUTION
•Read these instructions before commissioning the CA109 in order to familiarize yourself
with the device and its functions.
•Mounting and electrical installation are to be performed only by qualified technicians.
•Electrical connections between CA109 and other devices may only be created or fixed
when there is no power to the system. Otherwise, the devices may be damaged
•Conducting cross sections of the supply cable from the customer's power system should
be designed in accordance with the applicable standards.
•Use the device only under permitted environmental conditions (e.g. temperature,
grounding potential)
•The total continuous output of the beams is under condition of class 2
•Do not operate the device above the maximum rating condition, even momentarily. It may
cause unexpected permanent damage to the device.
•Do not directly look into the laser beam bare-eyed. The laser beam may cause severe
damage to human eyes.
•Optical Lens is made of glass. Do not contaminate lens with dirt, oil or chemical.

* Applies for well reflectivity target (e.g: Kodak white board), low background illumination, 25°C,
with a low reflectivity target, could decrease measuring range and increased errors which may
defer by target and environment situation, tolerances apply from 0.05 m to 10 m with a
confidence level of 95%. The maximum tolerance may deteriorate to 0.25 mm/m after 10
meters.
** Measuring range, accuracy is deeply related with measuring speed. A higher measuring
frequency will series effect range and accuracy, please do contact with our reps for more
discussion.
*** Need to be decided prior order.
**** Work with target CA6 target plate, under favorable condition, tolerances apply from 0.05 m
to 10 m with a confidence level of 95%. The maximum tolerance may deteriorate to 0.1 mm/m
after 10 meters
