HFBR-1506AM/HFBR-2506AM 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-1506AM and HFBR-2506AM products have a guaranteed performance up to 16 MBd. • • • • • • Meets Industrial SERCOS 16MBd standard SMA ports 650 nm wavelength Metal coated, plastic packaging Specified for use with 1 mm POF and 200 µm HCS DC - 16 MBd data rate Applications • Industrial Control Data Links • Factory Automation Data Links • Voltage Isolation Applications °, ±, ≥,≤,≠,∅, ∞,µ,π,ο,θ,λ, ρ,σ,γ,φ,η, δ,χ,β,α,Ω,, Σ,,,∏,, ∝,∂,τ,υ,ϖ, ω,ξ,ψ,ζ,∅, ≈,,, • • Bullet Bold Obsoletes: 5988-8402EN 5988-9121EN Package Information Recommended Chemicals for Cleaning/Degreasing The transmitters and receivers are housed in a lowcost, dual-in-line package that is made of high strength, heat resistant, chemically resistant and UL 94V-O (UL file # E121562) flame retardant plastic. Both the transmitter and receiver are coated with a layer of conductive alloy for better 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. 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. 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, 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. Table 1.

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-1506AM is compatible with SMA connectors. PIN 6 1 4 5 6 7 8 7 1 8 BOTTOM VIEW, HFBR-1506AM FUNCTION CONNECTED TO PIN 4 CONNECTED TO PIN 1 GND GND CATHODE ANODE SEE NOTE 10 Figure 1.

To further reduce the thermal resistance, the cathode trace should be made as large as is consistent with good RF circuit design. 4. Pins 1 and 4 are for mounting and retaining purposes, but are electrically connected, pins 5 and 6 are electrically isolated. It is recommended that pins 1, 4, 5 and 6 all be connected to ground to reduce coupling of elecrical noise. 3 Peak Output Power 0 °C to +70 °C unless otherwise noted.
