PREMO offers the market a wide range of transmitting antennas (standard catalog values) at 20, 125, and 134.2 kHz with various inductance-capacitor combinations and appropriate power ratings. All models in the KGEA series (BFCR, BFCWX, BFCAM, etc.) are designed with a special low-loss ferrite core and a special capacitor for high-voltage peak applications. The antenna complies with AEC-Q200, a quality standard specific to the automotive industry, and boasts an IP68 protection rating with a special composition and a high-strength plastic housing. The standard version of the KGEA series is supplied without a connector. If a connector is required, it will be added according to the customer's specifications (with or without special protection against water ingress).
The 3Dcoil series is offered in two different sizes, 3DC11LP and 3DC15, and three different formats: standard label, encapsulated (which offers greater resistance while maintaining virtually the same dimensions (13 x 11.6 x 3.6 mm) and without altering its electrical parameters), and foam, with a shock absorption system that improves the component's mechanical characteristics, especially in drop tests. These receiver antennas comply with AEC-Q200 standards and their main applications are passive keyless entry to vehicles, real-time location systems, access control, etc.
With a wide frequency range (15 to 150 kHz), the AS3933 offers designers a broad range of applications, including active RFID, item traceability, real-time location systems, people identification, wireless sensor networks, access control, and keyless remote access. The AS3933 provides a digital RSSI (Received Signal Strength Indicator) for each active channel. It also includes an internal clock generator derived from either a quartz crystal oscillator or an internal RC oscillator, and is the first device to provide an integrated antenna with an automatic tuner, which tunes the antenna to the desired frequency.
