HCS is a registered trademark of SpecTran Corporation. Description SERCOS SERCOS, an acronym for SErial Realtime COmmunications System, is a standard digital interface for communication in industrial CNC applications. SERCOS is a European (EN 9) and international standard (IEC 9). The optical interface allows data rates of 2,,, and MBd and data transfer between numerical controls and drives via fiber-optic rings, with voltage isolation and noise immunity. The HFBR- 0A and HFBR-20A products comply with SERCOS specifications for optical characteristics and connector style, and have guaranteed performance up to 0 MBd. (Typically the MBd required by SERCOS is possible as well but please contact Agilent regarding the plan for the MBd device.) PROFIBUS PROFIBUS, an acronym of PROcess FIeld BUS, is an open fieldbus standard defined for data rates ranging from 9. kbd to 2 MBd in selectable steps for wire and optical fiber. PROFIBUS is a German national DIN 92 standard and a European CENELEC standard EN 00. The ST connector is the recommended optical port of the PROFIBUS optical fiber version but other connectors are allowed as well. The HFBR-B and HFBR-2B comply fully to the technical guideline using Plastic Optical Fiber up to MBd, and have a guaranteed performance at data rates up to 0 MBd. (Typically the 2 MBd is possible as well, but please contact Agilent regarding the plan for the 2 MBd device.) INTERBUS-S INTERBUS-S, a special open Sensor/Actuator Bus, is finding a broad acceptance in the factory automation industry. The HFBR- 0C and HFBR-20C were specially designed for this application and can be used with mm POF and 200 µm HCS fiber at the specified data rates of 00 kbd and 2 MBd. The optical transmission guideline is a supplement of the German National DIN E 92 standard draft. On the European level,

2 pren 02 is the draft of the INTERBUS-S fieldbus. Package Information All HFBR-XXX series transmitters and receivers are housed in a low-cost, dual-in-line package that is made of high strength, heat resistant, chemically resistant and UL 9 V-O (UL file # E22) flame retardant plastic. The transmitters are easily identified by the light grey colored connector port. The receivers are easily identified by the dark grey colored connector port. The package is designed for autoinsertion and wave soldering so it is ideal for high volume production applications. 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. Recommended Chemicals for Cleaning/Degreasing XXX Products Alcohols: methyl, isopropyl, isobutyl. Aliphatics: hexane, heptane. Other: soap solution, naphtha. Do not use partially halogenated hydrocarbons such as,, trichloroethane, ketones such as MEK, acetone, chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride or N-methylpyrolldone. Also, Agilent does not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm. 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.
