Lens Evaluation Kit LH112/122
July 2020

PROPRIETARY AND CONFIDENTIAL
© 2018 by Acconeer
The Lenses are delivered as kits with two different lenses, a cover and a
holder. The holder comes in two versions LH112 used for XR112 and
XM112 and LH122 used for XM122. This getting started guide will show
you how to setup the lens evaluation kit.
We assume that you already have a sensor evaluation kit (EVK) XC/XR112,
or a module EVK XB/XM112 or XB/XM122 and that you are familiar with
how to use it.
Acconeer reference lenses are made of Polyamide PA12. They are solid.

How to Assemble LH112
4
First thing you need to do is to fit the
PCB into the Holder, which can be used
with Both XR112 (To the left) and
Acconeers XB/XM112 (To the right).
If using XB/XM112 we recommend
to also screw the PCB to the holder.
The exact sensor position in relation
to the lens will be important for
optimal performance.

How to Assemble LH122
5
First thing you need to do is to fit the
PCB into the Holder. After XM122 is
securely fitted you can easily connect it
to your XB122 breakout board if
needed. Be careful not try to fit the
holder to XM122 when it is connected
to the XB card. The connector is
sensitive and can break.
The exact sensor position in relation
to the lens will be important for
optimal performance.
To the right is an example how to NOT
place the sensor. Ensure that the BT
antenna always is placed in the gap of
the holder to ensure best performance.

Both the lenses can be fitted in the holder
in 2 different positions. D1 or D2. The
positioning numbering is identical for
LH122.
The cover is only used in D1.
The two positions will give you slightly
different performance. See next 3 pages
