Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20℃ +68℉.
2) In this light curtain, the floating blanking function can be set by using the Handy-controller (SF-HC)(optional). When the floating blanking function is used, the size of the min. sensing object is changed. For details on the floating blanking function, refer to SF4B series.
3) Vs is the same value as the voltage of the power supply to be used.
4) MS-SF2N-2 / MS-SF4A-H2 (U-shaped rear mounting intermediate supporting bracket) and MS-SF2N-L (L-shaped intermediate supporting bracket) are attached with the following light curtains.
The number of attached U-shaped rear mounting intermediate supporting bracket and L-shaped intermediate supporting bracket are different depending on the light curtain as follows.
SF4-AH36(-N/H), SF4-AH40(-N/H): 1 set
SF4-AH48(-N/H): 2 sets
