Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 ℃ +68℉.
Model Nos. having the suffix “G” are robust type.
2) PLe SIL3 compliant from production in August 2009.
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 min. sensing object is changed.
5) The outputs are not "OFF" when muting function is active even if the beam channel is interruped.
6) In case the blanking function is valid, the operation mode is changed.
7) Please use 12-core cable.
8) The manual reset and auto reset are possible to be switched depending on the wiring status.
9) In case of using optional function, the handy-controller (SFB-HC) (optional) is required. However, a handy-controller cannot be used with the SF4B-□-01<V2>, SF4B-□-03<V2> and the SF-C14EX-01.
