Thru-beam sensor ML4.2-P-20m-LAS/40b/76a/95/110

ML4.2-P-20m-LAS/40b/76a/95/110
  • Miniature design
  • Small light beam diameter for detection of small parts
  • Very short response time
  • Red laser as the light emitter
  • Test input
  • Not sensitive to ambient light, even with switched energy saving lamps
  • Protected against mutual interference (no cross-talk)
  • Metal-reinforced fastening holes

Please note: All product-related documents, such as certificates, declarations of conformity, etc., which were issued prior to the conversion under the name Pepperl+Fuchs GmbH, also apply to Pepperl+Fuchs AG.
