Auto Lock Function (Automatic Locking) The door is mechanically locked automatically just by closing it. There is no need for constant power supply, allowing for energy-efficient control circuits and system design. Pop-Up (Kick-Out) Function When powered, the lock is released, and the internal mechanism pushes the door forward. There is no need to install a handle on the door surface. This enables a flat and stylish housing design, reducing the procurement and assembly time for handle components. Shock Absorption (Damper) Function Equipped with an internal oil damper, it mitigates the impact and the "bang" sound or metallic noise when closing the door. Lock/Unlock Detection Function (Built-in Micro Switch) A micro switch capable of detecting locking, unlocking, and door status is standardly built-in. There is no need to separately place or adjust external sensors or switches, significantly reducing the hassle of wiring and positioning design. Emergency Unlock Mechanism Equipped with an emergency unlock lever on the back of the main unit, it allows for manual (or wire-operated) forced unlocking even during power outages or system failures. Safety design and countermeasures for unexpected troubles are standardly considered.

Ultra-thin design with a thickness of approximately 10mm (space-saving) It does not encroach on the limited installation space within the housing, maximizing the effective volume. Realization of "handle-less" design through pop-up (door ejection) function Simultaneously with the electric lock, the internal mechanism pushes out (kicks out) the door, allowing for a flat and aesthetically pleasing exterior design (handle-less design). Auto-lock function (one-touch locking) Simply pushing the door closed automatically holds and locks the latch, balancing user operability and safety. State detection with built-in micro switch Since it can obtain the state signals of locking/unlocking and door opening/closing, there is no need for additional sensors, reducing the complexity of circuit and mechanism design. Drip-proof performance (equivalent to IPX3) It can be safely adopted in environments where water droplets may occur, such as outdoor or semi-outdoor mailboxes and delivery boxes in apartment buildings. Standard equipped with emergency unlocking mechanism Even during power outages or system troubles, manual unlocking can be done from the rear lever (or wire connection), making it easier to meet safety design requirements.

One-push locking & automatic pop-up unlocking with electric power The door is securely locked just by pushing it in (passive locking). When powered, the lock jumps up in the direction of the door opening, incorporating a "kick-out (push-out) function" that allows the door to be slightly pushed open by itself. There is no need to design or place separate springs or push-out pins. "Door rattling prevention" through holder effect Equipped with a standard holder mechanism that suppresses rattling (play) when closed. This contributes to maintaining airtightness, vibration resistance, quietness, and enhancing the overall premium feel of the product. Built-in micro switch (signal detection of open/close and locking state) Without needing to install separate detection sensors, the electric lock can output signals for open/close and locking states on its own. This prevents the hassle of sensor position adjustments and the complexity of wiring design. Significant reduction in the number of parts and design man-hours through unitization Consolidating five functions—"solenoid unlocking," "latch holding," "door pushing," "rattling absorption," and "state detection switch"—into one unit. This simultaneously simplifies mechanical design and saves space.

Ultra-thin design with a thickness of only 10mm (space-saving) Design advantage: It can be easily placed in confined spaces with limited clearance around the internal casing and doors. This minimizes dead space and maximizes the effective volume inside the storage box. Electric lock with automatic pop-out function Design advantage: The latch engages mechanically just by pushing the door, and when power (DC24V) is applied, the lock mechanism simultaneously pushes the door open (pop-out function). This pop-out action eliminates the need for handles or knobs on the surface of the casing, achieving a flat and stylish exterior design. Incorporation of a wobble prevention mechanism Design advantage: A dedicated holding holder is standardly equipped at the fitting part of the receiving seat (keeper). This suppresses unpleasant wobbling and misalignment of gaps in the door when locked, enhancing the overall rigidity and quality feel of the product.
