Re: Electronic Latch
If you want to use it for door locking purpose,
you can try this product call "electric door strike".
https://www.smarthome.com/5192.html
Basically, the door operate like normal manual door,
where you have to turn the knob to open the door.
You can release the "door strike" using a voltage (example 12V)
applied to the strike.
The setup is similar in activating a relay.

Another product is the magnetic lock.
It works opposite, which requires power to lock the door.
Door strike, can lock the door without power.
Latching solenoid can also do the work.
It works also like a relay.
But the door locking mechanism will
not be compatiable to conventional door lock.
The door strike can be install easy,
and backward compatible to conventional manual door knob lock.
Hopes this can provide you with more idea.
