About hr electronic
hr electronic is a manufacturer specializing in inductive components, headquartered in Blumberg in the Schwarzwald-Baar district. The company winds coils in various designs – cylindrical, rectangular, triangular and flat coils as well as air-core, self-bonded (Backlack) and body coils – for low- and high-frequency applications. These include linear coils and thick-wire coils (wire gauge 0.3–1.8 mm, outer diameter up to 300 mm) for drive technology, gearboxes, gripping systems and electric motors, sensor coils, DCF77 antennas on ferrite cores, and antennas for RFID readers. A second pillar is RFID technology: the company manufactures custom transponders, NFC tags, transponder cards, key fobs, wristband transponders and PET inlays (disc tags). Proprietary processes such as thermocompression (wire bonding), injection molding and overmolding of polyamide, ultrasonic welding, laminating, laser marking and UV printing enable the entire value chain inhouse. As a holistic system provider, hr electronic develops complete assemblies together with customers and assembles electronic modules, for example for access control, payment systems and radio ripple control.

Materials & Processes
Copper wire
Base material for all coil and antenna windings, processable as thick wire from 0.3 to 1.8 mm.
Ferrite cores
Core material for DCF77 antennas with very tight tolerances.
ABS plastic
Injection molding material for robust, break- and impact-resistant key fob and transponder housings.
Polyamide
Used for overmolding transponders and makes the finished products water-resistant.
PET
Clear film for laminating transponders in waterproof disc tags (0.8 mm construction height).
PVC
Card material for RFID transponder cards with coating, pad printing or digital printing.
Stainless steel (polished)
Frame material of the SE key fob, metal-detectable for sensitive environments.
Perlon braid
Wristband material of the standard wristband transponders for high wearing comfort.
