Why stock a 10-pack of replacement caps?

The 6AV2181-8AV60-0AX0 is the value pack in the SIMATIC HMI touch pen cap range — 10 caps per order, twice the quantity of the RES, ELO, and V2A packs. These plastic caps are the standard 8 mm diameter tips that fit the majority of SIMATIC capacitive touch pens. They work on both capacitive and resistive screens, and the -40 to +80 °C operating range means they perform reliably in cold-storage HMI stations, outdoor kiosk panels, and hot production-floor pulpits alike. For facilities with multiple operator stations, the 10-pack reduces the per-station spares cost and ensures you are not reordering caps every quarter.

Which touch pens do these caps fit?

These 8 mm plastic caps are the standard replacement for SIMATIC HMI capacitive touch pens (the aluminum-body pen, 14 mm diameter, approximately 150 mm in length). They also fit many earlier-generation SIMATIC touch pens that use the same cap thread. If your pen body is a different diameter or thread specification — such as the slim 8 mm aluminum resistive pen (6AV6645-7AB14-0AS1) or the V2A universal system — check the cap compatibility before ordering. When in doubt, match the cap part number to the touch pen system it was ordered with.

Frequently Asked Questions

What is the difference between these caps and the RES/ELO/V2A types?

These general-purpose caps (6AV2181-8AV60-0AX0) are the standard plastic replacement tips supplied in a 10-pack. The RES caps (6AV6881-0AV63-0BA0) are resistive-only. The ELO caps (6AV6881-0AV61-0AA0) are also dual-technology but come in a 5-pack and are specifically for the ELO pen system. The V2A caps (6AV6881-0AV62-1AA0) are stainless steel for extended wear life. For most general-purpose SIMATIC HMI touch pens in mixed-technology environments, the 10-pack is the most economical stocking choice.

How do I store spare caps?

Store caps in their original packaging in the maintenance spares cabinet at ambient temperature. The wide -40 to +80 °C range applies to operation, not just storage — the plastic compound is formulated not to embrittle in cold or soften in heat within that window. Avoid storing caps in direct sunlight or in contact with solvents and oils.
