Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 ℃ +68 ℉.
2) The operating range is the possible setting distance between the emitter and the receiver.
The light curtain can detect an object less than 0.3 m 0.984 ft away.
3) MS-SF2-2 (intermediate supporting bracket) is attached with light curtains having 24, or more, beam channels.
The number of attached intermediate supporting brackets is different depending on the light curtains as follows.
SF2-EH24(-N), SF2-EH28(-N), SF2-EH32(-N), SF2-EH36(-N), SF2-EH40(-N), SF2-EH48(-N), SF2-EH56(-N): 1 set
SF2-EH64(-N), SF2-EH72(-N), SF2-EH80(-N): 2 sets
