P1-P3P4-P6P7-P8
Description
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.

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.
Notes:
1. 60 mA nominal drive current.
2. POF HFBR-Exxyyy 0.23 dB/m worst case attenuation.
3. HCS 10 dB/km worst case attenuation.
4. Including a 3 dB optical safety margin accounting for link service lifetime.
5. Including a 2 dB optical safety margin accounting for link service lifetime.
6. Signaling rate dc to 16 MBd.
Recommended Chemicals for Cleaning/Degreasing
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, Agilent does not recommend the use of cleaners
that use halogenated hydrocarbons because of their
potential environmental harm.
Package Information
The 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 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.
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.

HFBR-1506AM Transmitter
The HFBR-1506AM transmitter incoporates a 650nm
LED in a metal-coated, plastic 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-1506AM is compatible with SMA connectors.

Notes:
1. Typical data are at +25 °C
2. Thermal resistance is measured with the transmitter coupled to a connector assembly and fiber, and mounted on a printed circuit board.
3. 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.
Notes:
1. For I F_PK > 60 mA, the duty factor must maintain I F_AVG <= 60 mA and pulse width <= 1 µs.
2. 1.6 mm below seating plane.
