E-Mag triggers and HES sensor location?

[OPBN]

A couple of threads lately have come up regarding E-mag triggers and engineering issues due to the location of the HES magnet in the trigger. Has anyone ever tried moving the HES sensor farther back in order to allow a flatter trigger and farther back magnet location? Or am I missing a reason this wouldnt work? The cavity in which the HES sensor sits seems to have plenty of room for it to move farther back, is this possible?

It should be possible to move it as far back as the plug cavity for the HES.

Imagine the magnetic detection field is the distance of the activation point and the front of the HES.

Be sure to not short out the wire leads to the HES.

Another way to accomplish this would be to use a less powerful magnet (or a smaller one).

Might run into problems with the magnetic field created by the solenoid though.

It's possible but I thought that problem was greatly diminished by correcting the solenoid wiring so the field is produced away from the HES.

By moving the HES, you would loose your trigger adjustment. Why would you want to do that? Using smaller magnets like some aftermarket triggers have is also screwing with the trigger adjustment.

as an electrician

an analog hall sensor is basically a wire wrapped thru a "magnet" the more passes thru the magnet the more more sensitive to interference

hope this helps

got this from studying my tech manuals at work, yeah nuclear power did something for me today! go NAVY

Why? if the magnet in the trigger can be positioned fatther back,you could still make it adjustable. Would this mess with the ability to run it in mech?

I would think that the trigger was designed to fire at about the same position and that the adjustment was to allow for variances in magnet strength and HES sensor differences in case they needed to change suppliers.

So the questions are:

What are you trying to accomplish by moving it back?
Can it be done another way?

Is Mech or HES more important to you?

[OPBN]

Hate the bump in stock Emag triggers, and the way the magnet is mounted it makes it difficult to get a trigger that can sit farther back. I would have no problem with the magnet hanging out of the back of the trigger if moving the sensor farther back would allow for a flatter trigger.

Try to get one of the rare TL63 Triggers.
I had these in every X I've owned/own and prefer them over any aftermarket trigger out there.

Ask Rogue if he still has one for sale:

The issue is if you move the magnet forward or back you are moving the magnet either into or out of the engagement distance of the HES. Which would mean you are possibly either tripping the HES all the time or you will not ever trip the HES. The HES requires the magnet to be within a certain range (distance) from the HES.

The correct way to move the trigger magnet back would be to find a new HES switch that works in the distance range you want to put the magnet at. Mech issues are a whole other problem.

The reason the smaller not to spec magnets are screwing with things is they effectively change the distance by having a stronger or weaker magnetism.

"rare" being the optimal word here. It would be nice to have more choices.

Yeah, I get that, its why I asked about moving the HES.

I am far from an engineer, anybody have an idea on this one? Mech issues are a whole other problem. And I am guessing the Mech issues would be what will preclude it from being a good idea if someone wants to keep the mech option.

The reason the smaller not to spec magnets are screwing with things is they effectively change the distance by having a stronger or weaker magnetism.To clarify, I am not trying to get an existing trigger to work, I am trying to see if a solution to a design ovesight can be fixed.

I had considered using a Dremel on the stock trigger before I got the TL63.
