2-3 Wiring
<Series connection>
SF2B-H
□: Connectable up to 3 sets of the devices (128 beam channels max.).
SF2B-A
□: Connectable up to 3 sets of the devices (64 beam channels max.,
however, when 2 sets are connected, 96 beam channels max.).
This is the configuration for connecting multiple sets of emitters and receivers facing each
other in series. It is used when the dangerous part can be entered from two or more
directions. If any of the sets is in light blocked status, the control output (OSSD 1 / 2) turns
OFF.
For series connection, the cable for series connection ( SF2B-CSL
□) is required separately.
<Reference>
The wiring method depends on the type of bottom cap cable. Refer to ‘I nstruction Manual for
SF2B Series ’ for the details of wiring.
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 x 2) = Total number of beam channels
36 beam ch (44 beam channels x 2) = 124 beam channels
Connect the emitter of this main sensor ( SF2B-
□) and the emitter of the sub sensor
(this device), the receiver of this main sensor ( SF2B-
□) and the receiver of the sub
sensor (this device) respectively using the exclusive cable ( SF2B-CSL
□). Wrong
connection could generate the non-sensing area, resulting in death or serious
injury.
