Why Choose the ABB LS33P31B11 Limit Switch?
The ABB LS33P31B11, order code 1SBV012231R1211, is a compact and reliable electromechanical limit switch designed for precise position and movement detection in industrial machinery, automation equipment and control systems. As part of the ABB LS3..P standard limit switch series, it features a 30 mm wide fibre-glass reinforced UL-V0 plastic housing with double insulation for dependable industrial operation.
The LS33P31B11 features a Ø12.5 mm plastic roller lever on a steel plunger actuator designed for horizontal movement detection. Its 1 NO + 1 NC snap-action contacts use a Zb contact arrangement, providing complementary switching signals for machine sequencing, travel detection, position confirmation and automated control functions.
With IP65 protection, an ISO M20 × 1.5 bottom cable entry and two upper mounting holes, the LS33P31B11 is designed for straightforward integration into industrial machinery. Its roller-and-plunger arrangement supports smooth repeated actuation, while a maximum actuation speed of 1 m/s makes it suitable for a wide range of automated machine applications.

Reliable Position Detection for Industrial Machinery
Limit switches such as the ABB LS33P31B11 convert physical machine movement into an electrical switching signal. When a moving component contacts the roller lever and operates the steel plunger, the snap-action contacts change state, allowing the machine-control system to detect that a defined position or travel point has been reached.
The Ø12.5 mm plastic roller helps provide smooth repeated contact with moving components, while the steel plunger transfers this movement to the switching mechanism. Combined with the compact 30 mm housing, IP65 protection and 1 NO + 1 NC contacts, the LS33P31B11 provides dependable position feedback for industrial 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.
