HFBR-1506AFZ/HFBR-2506AFZ Full Metal Fiber Optic SMA Transmitters and Receivers for 16 MBd SERCOS Applications Data Sheet Description Features SERCOS, an acronym for SErial Realtime COmmunications Systems, is a standard digital interface for communication in industrial CNC applications. SERCOS is a European (EN 61491) and international standard (IEC 61491). The optical interface allows data rates of 2,4,8 and 16 MBd and data transfer between numerical controls and drives via fiber-optic rings, with voltage isolation and noise immunity. The HFBR-1506AFZ and HFBR-2506AFZ products have a guaranteed performance up to 16 MBd. RoHS-Compliant Meets Industrial SERCOS 16MBd standard SMA ports 650 nm wavelength Metal housing and port Specified for use with 1 mm POF and 200 m HCS DC - 16 MBd data rate Applications Industrial Control Data Links Factory Automation Data Links Voltage Isolation Applications Specifications and content subject to change without prior notification. Package Information Recommended Chemicals for Cleaning/Degreasing The RoHS-compliant transmitters and receivers are housed in a metal package that is high strength. Both the transmitter and receiver are built with metal housings and optical ports for excellence air discharge (ESD) performance. The package is designed for auto insertion and wave soldering so it is ideal for high volume production applications. Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane. Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as 1,1,1 trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride or N-methylpyrolldone. Also, Avago Technologies does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. Handling and Design Information When soldering, it is advisable to leave the protective cap on the unit to keep the optics clean. Good system performance requires clean port optics and cable ferrules to avoid obstructing the optical path. Clean compressed air often is sufficient to remove particles of dirt; methanol on a cotton swab also works well. CAUTION: The small junction size inherent in the design of these components increases the components' susceptibility to damage from electrostatic discharge (ESD). It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD. Table 1.

HFBR-1506AFZ Transmitter 4 The HFBR-1506AFZ transmitter incoporates a 650nm LED in a metal housing. The high light output power enables the use of both plastic optical fiber (POF) and Hard Clad Silica (HCS). This transmitter can operate up to 16MBd using a simple driver circuit. The HFBR-1506AFZ is compatible with SMA connectors. 5 PIN 6 1 4 5 6 7 8 7 1 8 BOTTOM VIEW, HFBR-1506AFZ FUNCTION CONNECTED TO PIN 4 CONNECTED TO PIN 1 NC NC CATHODE ANODE SEE NOTE 6 Figure 1.
