Why Choose the ABB LS33P52 / LS33P52B11 Limit Switch?
The ABB LS33P52B11, identified by ABB order code 1SBV012252R1211 and supplied under the LS33P52 designation, is a compact industrial adjustable rubber roller lever limit switch designed for reliable movement, position and end-of-travel detection. Part of ABB's LS3..P standard limit switch range, it combines an adjustable roller lever with a Ø50 mm rubber roller and 1 NO + 1 NC snap-action (Zb type) contacts.
The LS33P52B11 uses a fibre-glass reinforced UL-V0 plastic housing with double insulation and an IP65 degree of protection. Its standard mounting format incorporates two mounting holes at the top, while the bottom-mounted ISO M20 × 1.5 cable entry allows installation with a suitable industrial cable gland.
The adjustable rubber roller lever provides flexibility when matching the switch to cams, carriages and other moving machine components. A maximum actuation speed of 1 m/s, minimum operating torque of 0.1 N·m and positive-opening torque of 0.32 N·m support dependable repetitive operation in industrial automation applications.

Adjustable Roller-Lever Position Detection
The ABB LS33P52B11 converts mechanical movement into an electrical control signal, enabling machinery and automation systems to identify defined positions and travel limits. Its adjustable Ø50 mm rubber roller lever can be positioned to suit the movement of a cam, carriage or other machine component, providing rolling mechanical engagement during operation.
The combination of 1 NO + 1 NC snap-action contacts, positive-opening NC operation, IP65 protection and double-insulated construction makes the LS33P52B11 suitable for repetitive machine sequencing and position-monitoring duties. The M20 cable entry also provides a practical connection format for industrial control wiring.
Typical Applications
- Industrial machinery position and movement detection.
- Conveyor and material handling systems.
- Machine travel and end-position monitoring.
- Packaging and production machinery.
- Automated assembly and manufacturing equipment.
- Machine sequencing and industrial control systems.
