KeyFob Classic EM4200 with serial number

Robust, handy, safe—our key fob, with permanently programmed EM4200 transponder. The printed transponder serial number can be conveniently removed by sticker.

Identification media such as key transponders are handled several times a day. They are used both indoors and outdoors—so good quality is essential. That's why the KeyFob Classic EM4200 is made of high-quality Novodur plastic, so it is completely break- and bend-resistant. The ultrasonic welding of the cover part (pressure window) with the key fob ensures absolute watertightness and makes it impossible to open the key fob. That means it’s tamper-proof.

Keychain Classic The all-arounder

With our Classic key transponder, you are always on the safe side. Because as a true all-arounder, it will meet any demanding and multifunctional tasks. Its housing is very robust thanks to the ultrasonic welding of the cover part, as well as being kink and break resistant. And a lot is also possible in terms of visual design: personalized engravings and laser markings. Or standards, such as numbering—which is applied to the transponder under laminate using the thermal transfer process. We would also be happy to advise you on our selection of possible RAL colors and other versatile design and personalization options.

Another plus: the Classic is absolutely waterproof, which makes it ideal for leisure and swimming. Also important in this context: tampering with the transponder can be ruled out, as opening the key fob is impossible.
