3.1 Enclosure Design
The device should always be placed in an enclosure to protect the device and to guide inexperienced
cardholders in proper usage. Consider the following when designing the enclosure:

Overall dimensions of the device are shown in Figure 3-1
. The printed circuit board is 1/32” thick.
Detailed dimensions are shown in Figure 3-2 .

The device will work in any orientation, but MagTek recommends a horizontal orientation with the
large stainless steel plate facing the floor to meet cardholder expectations of inserting cards with the
chip facing the ceiling (see
Figure 3-3 ). Consider including visual features on the enclosure to guide
cardholders to insert contact chip cards properly.


On request, MagTek can provide a 3D model of the device’s envelope to assist with the mechanical
portion of solution design. MagTek recommends building 3D-printed prototypes with samples before
finalizing the solution design.

The mounting hole placements are provided in Figure 3-2 . MagTek suggests stainless steel screws
starting with sizes 0-80 or M1.6 , mated with threaded inserts in the enclosure. Make sure mounting
hardware in contact with the mounting holes conforms to grounding requirements in section 2
Electrical Integration .

Enclosure materials should meet UL rating 94 V-0. Examples include polycarbonate/ABS blends,
ABS, polycarbonate, and polypropylene.

The device is designed to withstand insertion forces up to 10N. To provide additional support, the
enclosure may incorporate features that buttress the chip card reader housing.

Be sure to provide at least 1/16 inch (1.5 mm) clearance from the large stainless steel plate of the chip
card reader housing to any portion of the enclosure to allow for soldering variations in different
boards (see reference clearance in
Figure 3-2 ).

The enclosure should have a card slot that aligns with the device’s chip card insertion slot. The
enclosure’s card slot should accommodate cards conforming to
ISO 7816 : Figure 3-4 , Figure 3-5 ,
and Figure 3-6 provide a reference card slot design to use as a starting point; features of the reference
design include adequate clearance to avoid cards hitting the sides, top, and bottom of the mDynamo
slot, and a cutout on one side of the slot to accommodate embossing on cards.
