*   InnuCase #2

    > a smaller case with display\
    > 1x M12 underside for sensor\
    > Case dimensions WxH 20x9cm\
    > File name: InnuCase-2\
    > ![InnuCase #1](https://4263638218-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fcd8WaQiNhLpQ99hwjXzs%2Fuploads%2Fgit-blob-8d8dfd4ffba661c2bc8a9eaea3413c5b0fe47b75%2FCase-2_Display.jpg?alt=media)

The InnuCase #2 is designed for a Brautomat with a display and a sensor. If no display is used, the display opening can be closed with a dummy cover.

Suitable connectors for M12 holes include [GX12 Aviation connector](https://www.amazon.de/dp/B0C6SJK1KZ/?coliid=I25GPP716VQUBU\&colid=I7GQB171JGLX\&psc=1\&ref_=cm_sw_r_cp_ud_lstpd_6Z58FR08HC6VACCZPY83). The GX12 Aviation sets are available as 2-pin (actors), 3-pin (DS18B20) and 4-pin (PT100x).

A [LED pressure switch](https://www.amazon.de/dp/B09WXPJQN3?psc=1\&ref=ppx_yo2ov_dt_b_product_details) latching is suitable as a power switch. The InnuCase-1 can accommodate two [PWM modules](https://www.amazon.de/dp/B0B7X6Z34Z/?coliid=I1KLJXGJL47O5M\&colid=I7GQB171JGLX\&psc=1\&ref_=cm_sw_r_cp_ud_lstpd_56603DDHC44WFNJ0BFM4). The cut-out for a PWM module can be closed with a dummy cover.

## Housing screw connection

The housing has several pads for a screw connection to accommodate [threaded inserts](https://www.amazon.de/dp/B0BZVGQ91H/?coliid=I1EM9CS796PWGZ\&colid=I7GQB171JGLX\&psc=1\&ref_=cm_sw_r_cp_ud_lstpd_64ER38VQR1H02DJ4WZ4A). The holes in the pads have a diameter of 4.6mm. The threaded inserts are melted into the pad holes using a [soldering iron](https://www.amazon.de/gp/product/B0CDBSGSXY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8\&th=1). Threaded inserts M3 are linked.

## PCB carrier

The circuit board is screwed onto a carrier plate. The carrier plate is mounted behind the display using [spacer sleeves](https://www.reichelt.de/distanzhuelsen-metall-6-kant-m3-15mm-da-15mm-p7018.html?CCOUNTRY=445\&LANGUAGE=de\&trstct=pos_0\&nbc=1&\&r=1). M3 hexagonal spacers with a length of 15mm are linked. ![PCB carrier](https://4263638218-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fcd8WaQiNhLpQ99hwjXzs%2Fuploads%2Fgit-blob-f30be7c1d57bea070a95c04bafcc357a2e524f10%2FPlatinentr%C3%A4ger-1.jpg?alt=media) ![PCB carrier MAX31865](https://4263638218-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fcd8WaQiNhLpQ99hwjXzs%2Fuploads%2Fgit-blob-eec64c5a0a21eb0dbf0e8a4e9816221c794261c5%2FPlatinentr%C3%A4ger-2.jpg?alt=media)

The illustration shows two PCB carriers:

* the lower, smaller carrier plate is for Brautomat with DS18B20 sensors
* the upper, larger carrier plate is for Brautomat with PT100x sensors (additional holes for holding 2 MAX31865 circuit boards)

The support plate allows complete installation in the housing. No Brautomat components or cables are attached to the housing cover.

## Bracket

Simple brackets are available for mounting the housing. The bracket is screwed onto the back behind the cover.

## Dummy cover

The dummy cover closes the display opening in the housing when no display is inserted.
