SF4B-C safety light curtain

Type 4 - compact safety light curtain.

Type 4 - compact safety light curtain

The compact safety light curtains with a thickness of only 20 x 27.4mm come with an ultra light housing. The combination of a plastic body with a metal inner frame is designed to minimize weight while at the same time increasing the toughness. The SF4B-C series is available as a hand protection type with a beam pitch of 20mm, allowing you to detect objects with a diameter as small as 25mm. The arm-protection type with its beam pitch of 40mm can detect objects of 45mm and larger. Both types offer an operation range of up to 7m. Cable and connector types are available.

Characteristics:

  • Side mounting possible to avoid dead zones
  • Very light weight due to combined metal/polycarbonate housing
  • Very compact dimensions (20 x 27.4mm)
  • Large multi-purpose indicator
  • PNP / NPN polarity switching
  • Beam alignment indicator
  • Interference prevention incorporated
  • IP65 protection
