Applicable standard
Notes: 1) The operating ambient temperature is +20°C unless otherwise specified.
2) The bottom cap cable (SF2B-CB05-B) (optional) cannot be used when the auxiliary output (AUX) is
used.
3) When SF2B-H□ and SF2B-A□ are combined in series connection, double the number of the beam
channels of SF2B-A□ to calculate the total number of beam channels, which should be 128 or less.
<e.g.>: The total number of beam channels for SF2B-H36 and SF2B-A44SL is 124.
The number of beam channels of SF2B-H36 + (the number of beam channels of SF2B-A44SL × 2)
= Total number of beam channels
36 beam channels + (44 beam channels × 2) =124 beam channels
4) The intermediate supporting bracket (MS-SF2B-2) is enclosed with the following devices. The quantity
of the enclosed bracket differs depending on the device as follows:
1 set: SF2B-H□...40 to 56 beam channels, SF2B-A□...20 to 28 beam channels
2 sets: SF2B-H□...64 to 80 beam channels, SF2B-A□...32 to 40 beam channels
3 sets: SF2B-H□...88 to 96 beam channels, SF2B-A□...44 to 48 beam channels
Both emitter and receiver are adjusted before shipment, please apply both emitter
and receiver with the same serial No. The serial No. is indicated on the plates of
both emitter and receiver. (Under the model represents the serial No.)
