What is the difference between SF100 and SF200?
The remote control is the same on both sets: LF200, 3xAAA battery-powered, IP64 protected, with a range of approximately 100 m in open field. The difference is in the receiver. The SF100's receiver is the panel-mount type LF100R, gives a 2x10A relay output and is supplied with 12/24V DC or 220V AC. The SF200's receiver is the LT200R: IP67 outdoor, with cable glands, a gasketed cover and a 12/24V DC supply.
SF100 and SF200 share the same remote control: the LF200, an IP64 protected transmitter running on 3xAAA batteries. Both sets are 2 channel (forward/reverse) and give a range of approximately 100 m in open field.
- SF100 receiver (LF100R): panel mounting, 2x10A relay output, 12/24V DC or 220V AC supply option.
- SF200 receiver (LT200R): IP67 outdoor housing, cable gland entry, gasketed cover, 12/24V DC supply.
The decision point is clear: SF100 if it will be built into a panel fed from the mains voltage, SF200 if the receiver will sit outdoors or on the machine. A 220V AC supply is not stated for SF200, so plan a 12/24V DC supply source.
No protection class is given for the SF100's receiver; the IP64 value belongs to the remote control. The protection class of the panel housing the receiver is your own responsibility. The SF200's relay current rating is also not stated; when making your load calculation, verify this value from the manual, and on large motors connect the relay output not directly to the motor but to the contactor coil.
