Zero-Force™ Touch Buttons

gbradley · Mar 12, 2015

Has anybody had any Experience changing standard Mushroom head Push buttons with 800Z Zero-Force™ Touch Buttons?
Do operators like them or Hate them?
I don’t have any experience at all, but I would think that they may take some getting used to.

I haven't used the AB models before but have used the Banner Opto-touch units extensively. The operators I've been around seem to like them and they are superior for ergonomics. I don't know options the AB units have but I would expect them to have some kind of shroud top prevent accidental operation.

I used them but it has been awhile. They are good for a setup where it requires the operator to have both hands on the operator buttons at the same time. Like a trim press etc. it helps with fatigue of Standred button pushing

We've used them over the Banner units in some operations. These use a double capacitive circuit of some sort. That way, they activate by a hand and not an object like a screwdriver or smock (Yes, that has happened with the Banners, even with a guard over them...

). They can however, be a bit finicky depending on the type of glove the operator is wearing.

Guards are also available for these.

We have Banner units on some equipment and the A-B units you show on some equipment. They work great, and as JordanCClark, the A-B units seem to be a little better at ignoring foreign objects.

They've been around a while now and they work good.

One shop I worked in removed all the Zero-Force buttons after one large breasted lady leaned into the machine to clean out the die & her breasts triggered the machine cycle - fortunately the machine was equipped with positive restraint pullbacks that she didn't disconnect before reaching in & they yanked her out of the machine.

I'd say thats funny if the end result wasnt so serious. Come to think of it, I believe I recall I've used them with the hoop style covers that only allows a hand to cover it coming in from the side.

Has anyone noticed how people tend to push harder on these buttons if something does not start right away? I guess subconciously humans are still expecting some kind of tactile feedback to their actions.

Did it have an anti tie down circuit?

I have known this to hapen with Zero force buttons that were not connected to an anti tie down relay but never with one.

Yes, it had proper 2-hand controls with anti-tie down that their mainenance department tested fully each PM. I wrote down the full proceedure & each step for them to follow & check off - it's just the operator happened to trigger the 2-hand cycle within the allotted 0.25 seconds with both buttons.
