do YOU know what a remote connector key is?

i noticed that close to the rear of high power handheld lasers there is a little headphone like jack that is called a remote connector key.... can we modify it so it is usable as a remote switch for on/off use. Ideal for tripod mount use where we don't have access to the power switch...

anyone? :whistle::whistle::whistle:
 





I don't see why not, at all. Though you'll still have to deal with the 5 sec FDA delay.
 
It's an interlock. It's a requirement for Class IIIb and IV laser systems. The plug that comes with it is a shorting plug to override the interlock. It is designed to be used as a remote shutoff for a predetermined event. Most of the time a laser interlock is wired to the case and to an entry door. Case interlocks prevent laser operation if the case or cabinet of the laser is opened. A door interlock shuts down the laser if the door to a lab is opened to protect anyone entering who might not be aware or protected.

so in other words, how do we make a switch or a remote shutoff from the plug?? is there a loop?
 
It's a continuity test. Open, the laser doesn't work. Closed, the laser works. Connect a switch to an audio plug. Set the switch to open, insert key, turn on laser, then close the switch, the laser will turn on, open switch, the laser will turn off.

I don't think the driver is built with any smarts. In real lasers (labs, etc), if the laser interlock is tripped you have to reset the system before it will work again but the handhelds tend to be very simple driver circuits so I don't think you will run into this issue.
