ZKTeco Digital Mini Lever Lock ML200

The ZKTeco ML200 is a digital mini lever lock for smartphone and passcode entry. It uses Bluetooth 5.0 and suits a door where a compact electronic lever arrangement is appropriate. This model does not list fingerprint identification, making the entry method an important distinction when comparing it with the related ML300 rather than assuming that both locks offer the same biometric functions.

The manufacturer lists a 100-user capacity and a 100-passcode capacity. Nearby Bluetooth management and remote access should be planned separately: a Bluetooth gateway is required for the documented remote-access arrangement. The ability to manage a lock locally does not therefore establish that it can be reached from another location without extra equipment. Match the intended phone, gateway and management workflow before selecting it for a remote-access project.

The mechanical specification lists an American-standard single latch, with a German-standard mortise as an option. Standard door thickness is 30 to 60 mm, and the single-latch version has an adjustable 60 or 70 mm backset. These dimensions help assess fit, but they should be considered alongside the door's existing preparation and the ordered mechanical version. Zinc alloy is used for the lever and front panel, with an ABS rear shell. Four AA alkaline batteries provide normal power and are not included. A Micro-USB backup-power interface is available for an emergency power connection rather than as the normal operating supply.
