Digit C1B Electronic Cylinder Adjustable 30/35?40/45mm Remote Code Black

Product Overview

The Digit C1B electronic cylinder is installed in doors within residential, rental, and small commercial properties, offering multi-factor access control for wooden and aluminium doors. Supporting door thicknesses from 35 to 80 mm and a variable cylinder size (30/35 to 40/45 mm), it is operated via PIN code, Mifare card or fob, fingerprint, mobile application, or mechanical key. Its high capacity supports up to 200 biometric fingerprints, 200 Mifare cards/fobs, and 150 PIN codes, functioning reliably in temperatures from -25°C to 60°C.

What distinguishes this model is its remote code delivery and time-limited access management, allowing administrators to grant, revoke, or restrict entry without internet or key handover. This eliminates lost-key risks and simplifies access control for short-term rentals, staff management, or service entry?making it particularly well-suited for property managers, serviced apartment operators, and B2B buyers prioritizing flexible, secure digital access.
