1SBV012241R1211 ABB LS33P41B11 Limit Switch 1NO+1NO Roller Lever

ABB LS33P41B11 (article 1SBV012241R1211) is a standard 30 mm wide limit switch for detecting mechanical position in industrial control applications. Its Ø18 mm plastic roller lever actuator and 1 N.O + 1 N.C snap action contacts make it a straightforward choice for end-of-travel and position sensing tasks. The housing is made from fiber-glass reinforced UL-V0 material, with a single ISO M20x1.5 cable entry at the bottom and two mounting holes at the top.
