Ever thought how useful it would be to have a swipe card as a master key in safety interlock systems? Well, Sigma Controls has introduced just that. With Sigma’s Prosafe safety interlocks, you can now have either a mechanical key or a swipe card as the master key actuation.
The swipe card gives you all the security features of the mechanical key, but a few advantages besides. It’s easy to carry around in a wallet, and if you need more, instead of having to specially order new keys, you can just create your own. The swipe units can be programmed to only pass certain keys and reject others.
