When an HMI in your PLC system starts acting up, downtime pressures mount. The Siemens KTP700 is a common operator panel, and the wear usually shows up where your fingers spend the most time: the membrane keypad and the touchpad. The natural question is whether to replace the whole unit or repair the worn interface. This guide walks through a specific repair option-the Siemens KTP700 Membrane Keypad + Touchpad 6AV2123-2GB03-0AX0 HMI Repair Kit at USD 181.39-and helps you decide if it solves your problem.
Quick verdict
If your KTP700's physical interface is the source of the trouble, this repair kit targets that exact area. It bundles the membrane keypad and touchpad into one product, and the 6AV2123-2GB03-0AX0 designation gives you a concrete part to match against your panel. The listed price of USD 181.39 makes it a smaller investment than a complete new HMI, but the used condition means you're taking on a component that has already served somewhere.
Who it suits
This is for technicians and maintenance teams who handle their own HMI repairs. The kit is not a full display unit; it's the face assembly you install onto your existing KTP700. If you can work through the teardown and reassembly steps, the kit offers a direct replacement for the parts that typically fail. It also works as a spare to keep on hand, so a scratched or unresponsive keypad doesn't idle a machine while you source a new panel.
What stands out from the listed details
Having the membrane keypad and touchpad together in one kit is the most useful feature. Rather than hunting for two separate parts, you get both in the same product. The item title and listing identify the 6AV2123-2GB03-0AX0 part number, which is the specific identifier for a KTP700 interface layer. The listing also marks the unit as used and notes a Country of Origin of China, so the price of USD 181.39 reflects a second-hand component rather than a factory-fresh one.
Meaningful trade-offs
The used condition is the trade-off to weigh. A replacement part like this has already been through a service cycle, which can shorten its remaining life compared to a new one. The listing shows a Custom Bundle answer of no, so you're buying only this repair kit, not a box of extras. For the price of USD 181.39, you get the membrane keypad and touchpad together, but the installation work and the outcome rest on your hands. It's a practical choice if you have the skill to do the swap, but not the route for someone expecting a brand-new part with zero service history.
Siemens KTP700 Membrane Keypad + Touchpad 6AV2123-2GB03-0AX0 HMI Repair Kit
At USD 181.39, this repair kit gives you the membrane keypad and touchpad together. The 6AV2123-2GB03-0AX0 part number is clear enough to identify the specific KTP700 interface. The trade-off is the used condition: you're getting a second-hand component that needs to be properly fitted. It's a practical choice for a technician who wants to restore a worn HMI without replacing the entire panel.
Bottom line
If a worn keypad or unresponsive touchpad is keeping your KTP700 out of service, this repair kit is a direct, cost-conscious fix. It bundles the two high-wear components for USD 181.39, and the 6AV2123-2GB03-0AX0 part number makes it easy to reference. Just go in knowing the used condition means you're responsible for the installation and the outcome.
