Limitorque Limit Switch Block Geared Cam Assembly 9–16 Amp for L120 Series

Limitorque Limit Switch Block for Reliable Position Control

This Limitorque geared limit switch block is a cam-operated, snap-acting assembly designed for legacy L120 Series electric actuators. It provides precise electrical signaling for open, close, and intermediate valve positions by using a gear-driven cam system that engages individually adjustable microswitches. Built for dependable mechanical operation, it ensures consistent position indication and protects the actuator by cutting motor power at preset travel limits.

Why It Helps
This switch block restores accurate travel limit operation in older Limitorque L120 actuators. Its geared cam mechanism delivers reliable, repeatable actuation of the internal SPST switches, supporting safe, controlled valve travel. By ensuring exact open and closed stopping points, it minimizes mechanical strain and maintains the actuator’s operational integrity.

Key Highlights

• Provides snap-acting electrical limit control using a geared cam assembly, enabling precise switching at defined valve positions.

• Includes multiple SPST contacts that can be independently adjusted to open or close at any rotational point in the actuator’s travel.

• Supports position indication and torque switch bypass functions in standard L120 actuator configurations.

• Designed for long-term durability with heavy-duty materials that match the performance of original Limitorque components.

System Compatibility
Compatible exclusively with Limitorque L120 Series actuators across models L120-10 through L120-2000. Not universal; must match the actuator’s mechanical switch compartment and gear train.

Applications
Ideal for restoring position feedback and travel limit control in industrial valve automation systems using Limitorque L120 actuators. Delivers stable performance and dependable operation in demanding service environments.
