*1 When using the SP series, the cable length is 2m, so “3600mm” is the maximum value.
*2 The optical fiber must not be bent within 25mm of the end of the fixing screw cap.
*3 For continuous use, use within the range of -40 to +130°C.

*4 The optical fiber is 2m long on one side, so the length is 4000mm.
