The Decision
When you're outfitting an industrial control system, the HMI is the part operators touch every day. Pick the wrong one and you're either forcing people to work on a display that doesn't fit the job, or adding a component that doesn't sit naturally with your PLCs. That's the trade-off between the Hope Industrial HIS-UM19-STAH and the Siemens 6AV6641-0CA01-0AX1.
Quick Verdict
If your priority is a large touchscreen with a tough enclosure, the Hope Industrial HIS-UM19-STAH is the more obvious operator interface choice. It is listed at USD 900.00 and described as New, built around the HIS-UM19-STAH model.
If you want a genuine Siemens Simatic HMI touch panel at a lower listed price, the Siemens 6AV6641-0CA01-0AX1 comes in at USD 685.35, also New. The platform alignment can make a real difference when the rest of your line is Siemens-based.
Side-by-Side Comparison

|---|---|---|
| Listed price | USD 900.00 | USD 685.35 |
| Price indicator | ||
| Brand | Hope Industrial Systems | Siemens |
| Type | Operator Interface Panel | Touch Panel |
| Touchscreen | Yes | Yes |
| Condition | New | New |
| Country of Origin | United States | Germany |
| Manufacturer part | HIS-UM19-STAH | 6AV6641-0CA01-0AX1 |
The two touch panels are closer than the price difference suggests on basics like new condition and touch input. The real split is the operator interface format and the control platform each one targets.
Where Each Panel Wins
- Hope Industrial HIS-UM19-STAH wins for operators who need a large 19-inch display and the physical protection of a stainless steel NEMA 4 IP65/66 enclosure.
- Siemens 6AV6641-0CA01-0AX1 wins for facilities already using Siemens controls and wanting an HMI touch panel that matches that environment.
Product Notes
Hope Industrial Systems HIS-UM19-STAH Operator Interface Panel
The Hope Industrial HIS-UM19-STAH is a 19-inch operator interface panel, and that screen size is the first thing to weigh. It is also listed with a stainless steel NEMA 4 IP65/66 enclosure, so it is a strong fit for production floors where moisture, dust, or washdown spray are part of the routine. The 100-240 VAC input range is another practical detail: it gives you flexibility when wiring the panel into a control cabinet. The limitation is physical scale. A 19-inch touchscreen is a large component, so you need to plan for the panel space it occupies and make sure the operator position works for your line. If the plan calls for a compact HMI, this is not that product.
Siemens 6AV6641-0CA01-0AX1 HMI Touch Panel
The Siemens 6AV6641-0CA01-0AX1 is a new HMI touch panel built for the Simatic controller platform. If your PLCs are Siemens, the part number and platform give you a clear family match. It is listed as a single unit (1PCS), which makes ordering straightforward, and the country of origin is Germany. The limitation is that it is a Simatic-focused panel, so if your plant is standardizing on non-Siemens PLCs, this HMI starts out as the odd fit. Touch input is there, but the reason to buy it is the Siemens part number and platform, and that only helps if the rest of the line is on Siemens controls.
Final Choice by Use Case
Choose the Hope Industrial HIS-UM19-STAH if the operator needs a large display and the panel will live in a demanding environment. Choose the Siemens 6AV6641-0CA01-0AX1 if your control architecture is already built around Siemens Simatic and a matching HMI makes the most sense for your PLC line.
