Why Choose the ABB LS33M41B11 Limit Switch?
The ABB LS33M41B11, order code 1SBV013841R1211, is a compact and robust electromechanical limit switch designed for reliable position and movement detection in industrial machinery, automation equipment and control systems. As part of the ABB LS3..M standard limit switch series, it features a 30 mm wide zinc-alloy (Zamak) metal housing with IP66 protection for dependable service in demanding industrial environments.
The LS33M41B11 features a Ø18 mm plastic roller lever actuator combined with 1 NO + 1 NC snap-action contacts in a Zb contact arrangement. The roller lever is designed for reliable mechanical actuation by moving machine components, making the switch suitable for travel detection, position confirmation, machine sequencing and automated control applications.
With a maximum actuation speed of 1.5 m/s, positive-opening operation of the normally closed contact and a rugged metal enclosure, the LS33M41B11 is well suited to repeated industrial operation. Two upper mounting holes provide secure mechanical installation, while the bottom ISO M20 × 1.5 cable entry enables straightforward integration into machine wiring systems.

Reliable Position Detection for Industrial Machinery
Limit switches such as the ABB LS33M41B11 convert physical machine movement into an electrical switching signal. When a moving component operates the roller lever, the snap-action contacts change state, allowing the associated control system to detect a defined position, monitor machine travel or initiate the next stage of an automated sequence.
The Ø18 mm plastic roller lever provides smooth mechanical interaction with moving components, while the zinc-alloy housing offers increased durability for industrial environments. Combined with IP66 protection and 1 NO + 1 NC snap-action contacts, the LS33M41B11 provides dependable position feedback for machinery and automated equipment.
Typical Applications
- Industrial machinery position detection.
- Conveyor and material handling systems.
- Machine travel and end-position detection.
- Packaging and production machinery.
- Automated assembly equipment.
- Machine sequencing and position feedback.
- Mechanical movement monitoring.
- OEM machinery and industrial automation systems.
