Internationally known for the latest sensor technology, Balluff is completing its safety range by including Category 2 and 4 photoelectric guards from Safety Controls. The three product lines Alfa 2, Alfa 4 and Linesmart have been developed by Safety Controls for applications where space is a problem and for extreme or wet applications where only an IP69 or IP67 protection rating is allowed.
The self-testing Alfa 2 photoelectric guard can be used where there are Safety Category 2 requirements. The Alfa 2 is available in 30mm, 80mm and multi-beam resolutions and boasts self-monitoring, EDM and blanking as well as cascadable options. Additionally, the IP69K versions are available for extreme applications.
Alfa 4 light curtains offer excellent performance for Category 4 requirements. The vast variety of functions, in particular the muting and cyclic operations, are available without additional devices. The Alfa 4 is available in 14mm, 30mm and multi-beam resolutions with floating/blanking, EDM, beam coding, cascadable options and an IP67 protection rating as standard. The closed sensor profile provides protection under extreme mechanical stress and can be used in a diverse range of applications, including material handling, automotive (welding cells) and food/pharmaceutical (IP69K versions) industries.
Linesmart is claimed to be one of the smallest Category 4 light guards available in the world. The profile is only 12 x 20mm and has an external control box with built-in safety relays. Two resolutions are available: 14mm and 30mm. The 14mm model has no dead zone, so is appropriate for applications where space is at a premium. When used with the protective housing made of V2A steel, the guard has an IP67 protection rating, which makes it suitable for wet areas and food processing applications.
