SF4B-H28C

Compact Safety Light Curtain Type 4

The SF4B-C series is designed to fit onto an aluminum frame, maximizing the machinery opening area. It can even allow zero dead zone. The SF4B-C series features a proprietary double structure of a "plastic body" with a "metal inner frame" which lightens the weight while maintaining the durability.Despite its compact, plastic body, the SF4B-C series features a metal inner frame that increases toughness and also keeps its enclosure not to curve. Thanks to its plastic body, the SF4B-C series is 45 % lighter* than previous models with aluminum enclosures. This helps to reduce the overall weight of the equipment during transport and when shipping it overseas.The SF4B-C series is equipped with the large multi-purpose indicator at the center of the unit. The indicator shows the presence of the safety light curtain, helping to prevent unintentional beam interruption. The indicator can be used in a variety of applications such as a muting indicator and work indicator.
Since a single model number can be switched between PNP and NPN input, fewer model numbers need to be registered. The ELCA function reduces interference without an interference prevention line.
