Notes:

1)	Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 ℃ +68 ℉.
2)	Except for SF4D-□-01, Korea KCs mark is acquired.
3)	The operating range is the possible setting distance between the emitter and the receiver.
4)	When the floating blanking function is used, the size of the minimum sensing object varies. For the detail, refer to the section on Safety distance.
5)	The power supply unit must satisfy the following requirements: 1) The power unit must be certified for use in your region. 2) Use of the product as a unit in compliance with CE Marking: SELV (safety extra low voltage) / PELV (protected extra low voltage) power supply unit in conformity with EMC Directive and Low Voltage Directive. 3) Use of the product as a unit in compliance with UKCA Marking: SELV (safety extra low voltage) / PELV (protected extra low voltage) power supply unit in conformity with EMC Regulations and Low Voltage Regulations. 4) When using a commercial switching regulator, the frame ground (F.G.) terminal must be connected to ground. 5) The power supply unit must have an output holding time of 20ms or more. 6) If surges occur, take countermeasures such as connecting a surge absorber to the source of the surges. 7) The power unit must be a CLASS 2 compliant unit. (When CTÜVUS mark compliance is required.)
6)	In consideration of the voltage drop caused by the cable, use Control output (OSSD 1, OSSD 2) source / sink current and cable length as a guideline.
7)	The setting can be changed when the SF4D-TM1 (optional) and Configurator Light Curtain setting software are used. Note that the setting cannot be changed when SF4D-□-01 is used.
8)	For response times by number of beams, refer to the Control output (OSSD 1, OSSD 2) OFF response times.
9)	Because the control output (OSSD 1, OSSD 2) must be OFF for at least 80 ms, the ON response will be delayed more than 50 ms when the light blocked time is less than 30 ms.
10)	When optical synchronization is selected, if the beam axes of both the top end and bottom end are blocked, the ON response speed decreases by as much as 1 sec.
11)	To use optional functions, the SF4D-TM1 (optional) and Configurator Safety Light Curtain setting software are required. Note that optional functions cannot be used when SF4D-□-01 is used.
12)	Do not use or store in an environment pressurized to atmospheric pressure or higher at an altitude of 0 m.
