HFBR-0600Z Series SERCOS Fiber Optic Transmitters and Receivers Data Sheet SERCOS Features SERCOS is a Serial Realtime Communication System, a standard RoHS compliant digital interface for communication between controls and Fully compliant to SERCOS optical specifications drives for numerically controlled machines. The SERCOS Optimized for 1 mm plastic optical fiber interface specification was written by a joint working group of Compatible with SMA connectors the VDW (German Machine Tool Builders Association) and ZVEI Auto-insertable and wave solderable (German Electrical and Electronic Manufacturers Association) Data transmission at symbol rates from DC to over 2 MBd to allow data exchange between NC controls and drives via for distances from 0 to over 20 meters fiber optic rings, with isolation and noise immunity. The HFBR-0600Z family of fiber optic transmitters and receivers comply to the SERCOS specifications for transmitter and Applications receiver optical characteristics and connector style (SMA). Industrial control data links Reduction of lightning and voltage transient susceptibility Description Tempest-secure data processing equipment The HFBR-0600Z components are capable of operation at Isolation in test and measurement instruments symbol rates from DC to over 2 MBd and distances from 0 to Robotics communication over 20 meters. The HFBR-1602Z and HFBR-1604Z transmitters contain a 655 nm AlGaAs emitter capable of efficiently CAUTION The small junction sizes inherent to the design of launching optical power into 1 mm plastic optical fiber. The this component increase the component s optical output is specified at the end of 0.5 m of plastic optical susceptibility to damage from electrostatic fiber. discharge (ESD). It is advised that normal static The HFBR-1604Z is a selected version of the HFBR-1602Z, with precautions be taken in handling and assembly power specified to meet the SERCOS high attenuation of this component to prevent damage and/or specifications. degradation that may be induced by ESD. The HFBR-2602Z receiver incorporates an integrated photo IC containing a photodetector and DC amplifier driving an open-collector Schottky output transistor. The HFBR-2602Z is designed for direct interfacing to popular logic families. The absence of an internal pull-up resistor allows the open-collector output to be used with logic families, such as CMOS, requiring voltage excursions higher than V . The CC HFBR-2602Z has a dynamic range of 15 dB.
