Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of + 20 °C + 68 °F.
2) When using auxiliary output (AUX), the SF2B-CB05-B adapter cable (optional) cannot be used.
3) The SF2B-H8- and SF2B-A4- cannot be connected in series.
4) If using the SF2B-H and SF2B-A together in a series connection, only the number of beam channels for the SF2B-A must be doubled, and the total number of beam channels must be 128 or less.
Example: If using the SF2B-H36 and SF2B-A44 in a series connection, the total number of beam channels will be 124.
Number of SF2B-H36 beam channels + (Number of SF2B-A44 beam channels x 2) = Total number of beam channels 36 beam channels + (44 beam channels x 2) = 124 beam channels
5) The intermediate supporting bracket MS-SF2B-2 is enclosed with the following models. The quantity of the enclosed bracket differs depending on the model as follows:
1 set: SF2B-H ・・・ Light curtain with 40 to 56 beam channels, SF2B-A ・・・ Light curtain with 20 to 28 beam channels
2 sets: SF2B-H ・・・ Light curtain with 64 to 80 beam channels, SF2B-A ・・・ Light curtain with 32 to 40 beam channels
3 sets: SF2B-H ・・・ Light curtain with 88 to 96 beam channels, SF2B-A ・・・ Light curtain with 44 to 48 beam channels
