EMPLOYING RFID tag technology allows these safety switches to meet high safety category requirements in sensing safety gate and safety related machine position sensing applications.

Jemtech’s VSX-RA safety module and associated heads and tags places an evaluation unit with safety switching relays in the customer’s machine control cabinet.

The small size tags, only 25mm x 41mm x 12mm in size can be placed on the machine up to 20m away. Tags will switch on at 4mm separation and off at 10mm giving great tolerance to misalignment and vibrations.

Being small allows the tags to be fitted conveniently out of harms way on the machine. Each evaluation module can switch one or two tags.

The devices meet AS4024 and eN954 design requirements. They easy to use due to the tolerance to misalignment between the key and the head that senses the position.

With direct relay output switching up to 6A, no further hardware is required for a complete safety gate system.

Jemtech has successfully installed the VSX series switches on presses, robot cells, milling machines and roll-forming machines to date.
