ES 61 WHL 2Ö

Position switch with safety function
Material number: 1047971
(Material number old: 61516001)
  • Metal enclosure
  • Slow action , 2 NC contacts with double break
  • 3 cable entries M20 x 1.5
  • Actuator: Long roller lever with collar WHL
  • Actuating speed max. 0.5 m/s with a vertical actuating angle
    of α = 40° and β = 30°
  • Wear-resistant plastic roller
  • Actuator can be repositioned by 4 x 90°
  • Watertight collar for protection against penetration of dirt
  • Actuation from the left should be avoided since this reduces the mechanical life of the position switch.
  • With metal roller available on request
  • When used as safety switch, secure the enclosure against slipping with appropriate means, e.g. pinning.
