Electronics integrated in the cylinder
The cylinder itself is replaced by a cylinder with the motor, battery and radio inside. The outside keeps a mechanical keyway; the inside is a motorised knob. Nothing else on the door changes.
Applies to these lock types
Euro profile cylinder in a mortise case (DIN) · UK oval cylinder (uPVC and composite doors)
Measurements this architecture needs
- Cylinder total length and halves (e.g. 35/35)
- Key profile
- Cam type and clock position
- Handing (DIN left / right)
Adapter interfaces to design
- Full cylinder length matrix (e.g. 30/10 up to 45/55) and the extendable-cylinder mechanism
- Profile variants: euro DIN, UK oval, Scandinavian round/oval
- Cam clock positions and cam thickness for the target lock case
Design targets
Targets marked "from standard" come from the cited document. Targets marked "practice" are our engineering guidance and must be verified for your design.
| Target | Value | Basis |
|---|---|---|
| Battery life | ≥ 12 months at 8 cycles/day |
practice The main reason this architecture exists: the motor turns only the cam, not a knob through a clamp, so it is far more efficient. |
| Security rating | EN 1303 class 6 / TS007 3-star where the door needs it |
from standard Replacing the cylinder gives up the existing anti-snap cylinder unless the replacement carries the same rating. |
Known blockers
- Sacrifices the security rating of the cylinder it replaces unless the replacement is equally certified.
- Keyway and key control change — a real objection for keyed-alike estates.
- Electronics inside a part exposed to weather and attack needs potting and a hardened body.
Design checklist
- Cover the length matrix, or offer a measuring gauge and ship the right size.
- Keep a permanent mechanical override that works with zero battery.
- Do not weaken anti-snap: if the old cylinder was 3-star, the new one must be too.
