Teknik Özellikler
HFBR-2521Z is a Broadcom (Avago) Versatile Link industrial fiber optic receiver belonging to HFBR-0500Z series, designed for short-distance digital communication via plastic optical fiber (POF) with robust galvanic isolation and strong EMI/RFI suppression for high-noise power and automation equipment.
👉 It’s not a high-speed multi-gigabit single-mode fiber receiver for long-distance telecom transmission.
👉 It’s a low-cost industrial-grade plastic fiber receiving module with open-collector TTL output, ideal for isolating control signals in inverters, motor drives and factory automation fieldbus systems.
Key Features of HFBR-2521Z Fiber Optic Receiver
Power electronics and automation engineers select HFBR-2521Z for reliable isolation, wide temperature adaptability and simplified system layout:
- Maximum data transmission rate up to 5 MBd DC-coupled digital signal receiving capability
- Peak sensitivity wavelength at 660 nm, matched with HFBR-1521Z fiber optic transmitter for complete fiber link
- Supports 1 mm core plastic optical fiber (POF) and 200 μm HCS hard-clad silica fiber; stable transmission distance up to 20–30 meters at room temperature
- Integrated monolithic receiving IC with built-in photodiode, transimpedance amplifier and Schottky open-collector output; internal pull-up resistor optional for circuit design
- Integrated metal shielding structure to suppress external electromagnetic interference and switching noise
- Typical rise time 80 ns, fall time 40 ns, automatic pulse width calibration to limit pulse distortion within ±20 ns
- Single 5V operating supply voltage (4.75 V ~ 5.25 V), low quiescent current consumption for continuous long-term operation
