Panasonic SF2C series is made of resin that is lighter than the conventional aluminum case type. Its lightweight body eases the burden on the mounting surface of the equipment and contributes to overall reduced weight during equipment transportation or overseas shipment. The standard mounting bracket is already mounted for easy installation. An IP67 (IEC) rating is achieved with an ultra-slim size for protection from environmental factors by a new method. Light curtain wiring consists of just five wires each for the emitter and receiver, allowing you to easily implement safety measures in about the same amount of time as with an area sensor. The emitter has an effective aperture angle of ±5° or less for an operating range of 3 m 9.843 ft. Compared to Type 4 light curtains (which have an effective aperture angle of ±2.5° or less), the SF2C series is easy to align and install.
