Interface and construction checks

This model includes a signal microswitch and provides more than purely mechanical tailpiece drive. Check contact definitions, wiring and controller requirements before installation. The catalogue gives no electrical load rating on this page; do not assume it can switch lock power directly.

What to confirm before replacement

Provide the supplier with complete model 87RA26M259.F, the original lock-case identification and photographs of the connections. Check tail drive, fixing method and operating functions separately; a similar key shape within the same series does not replace compatibility confirmation.

Pin and key material information comes from the corresponding catalogue section; dimensions and application conditions follow the model line and drawing. When replacing paired inner and outer components, first confirm both sides' construction and operating direction on the original lock.

Limitations

• Confirm the catalogue model and compatible-series description against the installed lock and with the manufacturer. They do not establish universal compatibility with all locks of the same brand.
• Current stock, supply configuration and regional certifications have not been independently verified.
