Why Choose the ABB LS35P11L20 Limit Switch?
The ABB LS35P11L20, order code 1SBV012111R1320, is a compact 30 mm industrial limit switch designed for reliable position and end-of-travel detection in machinery and automation systems. It features a glass-fibre-reinforced UL-V0 plastic enclosure, a plain steel plunger actuator and a standardised form suitable for straightforward machine integration.
The LS35P11L20 incorporates 2 normally open (2NO) slow-action, simultaneous contacts. Both contacts change state together as the steel plunger reaches its operating point, making this model particularly useful where two normally open control circuits need to be switched simultaneously from one mechanical movement.
With IP65 protection, Class II double insulation and a bottom 1/2-inch NPT cable entry, the LS35P11L20 is well suited to industrial machinery installations. Its compact 30 mm body, high mechanical endurance and plain steel plunger provide dependable direct actuation by cams, stops and other moving machine components.
Key Advantages
- Compact 30 mm industrial limit switch for machinery position detection.
- Plain steel plunger for direct and repeatable mechanical actuation.
- 2NO slow-action simultaneous contacts for switching two circuits together.
- IP65 protection for industrial environments.
- Glass-fibre-reinforced UL-V0 plastic enclosure.
- Class II double-insulated construction.
- Standardised plunger configuration conforming to EN 50047.
- Suitable for machine tools, conveyors, packaging machinery and automated equipment.
Key Features
- ABB LS35P11L20 limit switch.
- 30 mm-wide standard plastic enclosure.
- Plain steel plunger actuator.
- 2 normally open (2NO) contacts.
- Slow-action, simultaneous switching.
- Contact terminals 13-14 and 23-24.
- 10 A conventional free-air thermal current.
- IP65 / UL Type 4 enclosure protection.
- 1/2-inch NPT bottom cable entry.
- 0.5 m/s maximum actuation speed.
- 9 N minimum actuation force.
- Operating ambient temperature from -25 to +70 °C.
Simultaneous Two-Circuit Position Switching
Slow-action limit switches change contact state according to the mechanical travel of the actuator rather than using a snap mechanism. With simultaneous contacts, both output circuits operate at the same actuator position, making this arrangement useful where a single machine movement needs to provide two coordinated normally open signals.
The ABB LS35P11L20 combines a plain steel plunger with 2NO simultaneous slow-action contacts in a compact IP65 enclosure. Its standardised 30 mm form and direct plunger operation make it suitable for reliable position detection on machine tools, conveyors, production machinery and automated equipment.
Typical Applications
- Machine position and end-of-travel detection.
- Simultaneous switching of two control circuits.
- Industrial conveyors and material handling systems.
- Packaging and production machinery.
- Machine tools and automated equipment.
- Cam and mechanical stop detection.
- Factory automation and industrial control systems.
