Emas L5K13MEL123 Elevator Limit Switch – Adjustable Rubber Roller Lever, 1NO+1NC, Snap Action

This Emas L5 series limit switch, easily identifiable by its blue actuator head and grey body, is designed for reliable position detection and control in various industrial applications, and is commonly utilized for critical functions within elevator systems. It features a durable plastic housing and an adjustable metal lever actuator with a serrated angle adjustment mechanism, equipped with a 50mm black rubber roller for versatile sensing. The snap-action mechanism ensures precise and rapid switching. Mounting is straightforward with standard M4 holes (20/22 mm spacing) clearly marked on the housing.

Key Features:

• Elevator System Ready: Ideal for monitoring and controlling elevator car position, safety gear status, and other position-dependent functions.
• Durable Construction: Robust plastic body (grey) and actuator head (blue) suitable for the demands of elevator shafts and machine rooms. Made in Türkiye.
• Adjustable Actuator: Features a 50mm rubber roller on a metal lever with a serrated base for precise angle adjustment, allowing interaction with cams or ramps in the shaft. Can operate in both directions.
• Precise Switching: Snap-action contacts (1 Normally Open + 1 Normally Closed) provide quick and reliable signals to the elevator control panel.
• IP65 Protection: Offers high protection against dust ingress and water jets, suitable for potentially damp or dusty shaft environments (when used with appropriate cable fittings).
• Standard Compliance: Designed and tested according to IEC/TS EN 60947-5-1, UL 508, and VDE 0660 standards, ensuring reliability and safety (CE, UKCA, UL Listed, VDE marked).
• Versatile Connectivity: Features one threaded cable entry (appears suitable for PG13.5 / M20x1.5). Requires a listed conduit fitting (DWTT) appropriate for raintight, liquidtight, oiltight, or watertight applications to maintain IP rating.
• Reliable Contacts: Silver Nickel (AgNi) contacts ensure good electrical conductivity and long service life.
• Easy Mounting: Standard M4 mounting holes with 20/22 mm spacing indicated on the body for installation on brackets or structures within the elevator system.
• High Endurance: Built for long mechanical and electrical life cycles, critical for elevator operation.

Typical Elevator Applications:

This type of limit switch is frequently used in elevator systems for:

• Detecting Elevator Car Position:
  • Final upper and lower travel limits (stopping the car at the end of the shaft).
  • Initiating slowdown sequences as the car approaches terminal floors.
  • Confirming car position for leveling or specific floor zones.
• Monitoring Safety Components: Confirming the status of speed governors or safety gear mechanisms.
• Installation: Typically mounted on the elevator car to interact with cams/ramps in the shaft, or sometimes mounted fixed within the hoistway (shaft) itself. The signals generated are sent to the main elevator control panel.
