Electronic Latch Lock 3792 (5V) & 3793 (12V)

Electronic Latch Lock 3792 (5V) & 3793 (12V)
Technical Drawing

The 3792 (5V) and 3793 (12V) e-latches incorporate a range of innovative features. These include both key and mechanical cable override of the electronics, a floating door strike/bolt system to accommodate mis-alignment over time, and a precision motor driven latching mechanism with excellent operation even under load.

These latches have been designed for easy connection and control and include an internal sensor for feedback on whether the door is closed. They have a push-to-lock action and on latch release will pop the door slightly ajar. For greater door movement a spring-loaded plunger is available as a replacement for the mechanical key override system.

The latches are supplied with a door mounted striker bolt (customer to specify flush fit or 2mm stand-off) and come with a 2, 4 or 6 meter cable (customer to specify)‚Äč.

Rigorously tested for durability and reliability, these latches are ideal for use on a wide variety of applications such as personal lockers, postal and delivery systems, asset management systems and other enclosures.

Electrical Information

The latch input and outputs connect directly to an on-board microprocessor (uC). There is one input to specify lock/unlock (2). This is internally pulled up. When it is connected to VCC (1) or left unconnected the latch will be locked. The latch will unlock when lock/unlock (2) is pulled low (connected to ground) for longer than 10ms.

There are three outputs that indicate the status of the latch. The presence of a latch is indicated by a low signal on the latch present output (3).

The locked status (4) indicates whether the latch is in the locked position (high) or not (low). When this output is high the latch internally is in the locked state. If the door is still open, it will be locked shut when it is next closed.

The latched status (5) indicates whether the striker bolt is latched into the lock (high) or not (low). This identifies whether the door is shut and locked or not. If the latch is unlocked (see above), the latched indicator will always be low.
