StealthyBlagga Posted January 21, 2019 Share Posted January 21, 2019 (edited) I want to put s sensor on a steel STOP plate that will work with .22 rimfire. I have two timer types - CED6000 and ProTimer IV Super - at my disposal, both of which have sensor inputs that work with a normally-closed micro switch. Can anyone here recommend a specific brand/model of sensor that is known to work well in this application, and describe how it is set up relative to the plate? The ProTimer IV Super user manual lists the OMRON Z-15G-B7-K as a suitable device. It is a pin plunger micro-switch (0.5mm travel), but it is not clear to me how it should be used. Does it sit between the plate and the 2x4 post? If anyone has photos of a known-reliable setup, please post them here.

scffacenter1 Posted January 21, 2019 Share Posted January 21, 2019 i have not seen these particular pin switches used, but I would have it mounted to the side of the 2x4 and have a set of slotted holes for it to be finely adjustable. if .5 mm is total travel distance, I would also have an adjustable plate stop built into the mounting bracket to keep the plate from battering the switch when (if) the larger calibers are used Link to comment Share on other sites More sharing options...
stango424 Posted January 21, 2019 Share Posted January 21, 2019 Just curious but what is the need for a sensor on the stop plate? Are sound actuated timers not reliable or accurate enough? Link to comment Share on other sites More sharing options...

rowdyb Posted January 21, 2019 Share Posted January 21, 2019 (edited) Would the same type of relay and set up used for the diy flashers you see on distant 3 gun steel targets work? But rather than setting off a camera flash have them do something for the timer? I know what you're asking for has been done before, but I have no idea myself how to do it.

Ah I get it now, well good luck on your pursuit. At least you are going the extra mile to get it right so good on you. Link to comment Share on other sites More sharing options...
1911luvr Posted January 23, 2019 Share Posted January 23, 2019 If it were me I’d use a simple piezo-electronic impact sensor like those used in a car alarm:https://shop.controleverything.com/products/piezo-knock-vibration-or-shock-sensorSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
309jdj Posted February 1, 2019 Share Posted February 1, 2019 You would need to make sure you could adjust the sensitivity so it wouldn't be triggered if someone hit the wood post instead of the plate. Link to comment Share on other sites More sharing options...
