What this part is
The SF4B-F71(V2) is a Panasonic SF4B series light curtain with 71 beams at a 10 mm beam pitch, giving it a 14 mm detection capability for finger protection. The protective height is 710 mm, and the operating range spans 0.3 m to 7.0 m. It runs on 24 VDC and carries an IP65/IP67 ingress rating, so it handles dust, water jets, and temporary submersion.
Integration notes
Mounting: the SF4B series uses standard brackets; the 710 mm protective height means the emitter and receiver columns need a clear path across that span. Wiring: 24 VDC supply, typically with a safety PLC or relay interface. The blanking and muting functions are configurable — refer to the manual for setup. The IP65/IP67 rating allows installation in washdown zones, but keep the connector and cable entry sealed.
