Choosing an operator interface for an automation project usually starts with a split: do you want a complete touch panel you can mount on a machine, or a display interface you can build into your own control design? In the PLC and HMI space, the Crouzet MTP8/70 HMI user kit and the Infineon XMC4500 OLED interface kit sit on opposite sides of that split. The Crouzet is a touch panel user kit built around the Millenium 3 PLC line. The Infineon is a board-level OLED display interface for XMC4500 development. Your choice depends on whether you need an integrated machine interface or a flexible starting point for custom HMI hardware.
Quick verdict
If you need an operator touch panel for a Millenium 3-based machine, the Crouzet MTP8/70 is the product to plan around. If you need a low-cost way to add an OLED display to a custom embedded project, the Infineon XMC4500 kit is the more practical starting point. The listed prices run from USD 50.00 to USD 1,971.92, so the decision is also about the scale of your project investment.
Side-by-side comparison
The table below summarizes the listed prices and the relative price positions of the two products.
| Product | Listed Price | Price Position |
|---|---|---|
| Crouzet MTP8/70 HMI user kit | USD 1,971.92 | |
| Infineon XMC4500 OLED interface kit | USD 50.00 |
That price split reflects the different jobs. The Crouzet kit is the higher-investment route, but it also removes the need to assemble a display module into your own board. The Infineon kit is the lower-investment route, but it expects you to handle the surrounding hardware.
Where each product wins
- Crouzet MTP8/70 HMI user kit: the right fit when you want a complete touch-panel interface from the Millenium 3 family, and you are planning a machine-level investment.
- Infineon XMC4500 OLED interface kit: the right fit when you want an inexpensive interface board for an OLED display, with a clear part number, and a smaller initial spend.
Product notes
Crouzet MTP8/70 HMI User Kit
For a machine that needs an integrated touch panel, the Crouzet kit sits at the top of the price spread. It is listed as a new open-box item with part number MTP8/70 88970496 / 88970495, and it is tied to the Millenium 3 platform. That makes it a straightforward match when your project calls for a complete HMI rather than a bare display module. The obvious limitation is its position at the high end of the price spread: this is a serious line item for a machine build, so you should only head this way if the machine really needs an integrated panel. For a Millenium 3 control cabinet or a one-off machine retrofit, the Crouzet kit gives you a defined touch-panel HMI without assembling display hardware yourself.
Infineon XMC4500 OLED Interface Kit
The Infineon kit takes the opposite approach. It is a new board-level OLED display interface with part number KIT_XMC4X_HMI_OLED_001, aimed at XMC4500 development. It is the lower-cost starting point in this pair, which makes sense if you are prototyping or building a custom embedded HMI. The trade-off is that the item is described as shipped as pictured with no additional parts or accessories included. In other words, you are working with the interface kit itself rather than a finished touch-panel product. If your goal is to bring an OLED display into a design you control, the Infineon kit keeps the initial outlay modest and gives you a clearly defined component to build around.
Final choice by use case
For a production machine that needs an operator touch panel, choose the Crouzet MTP8/70 HMI user kit. For a custom control board where you plan to design your own display interface, choose the Infineon XMC4500 OLED interface kit.
