Technical Overview

The Omron WLCA12-N is a heavy-duty, 2-circuit limit switch designed for industrial environments. It features an adjustable roller lever actuator with a sintered stainless steel roller, an SPDT (SPST-NO + SPST-NC) contact configuration, and a rugged IP67-rated enclosure. It delivers high durability with a mechanical life of 15,000,000 cycles and handles versatile electrical loads up to 10A at 250VAC.

Key Features

  • Adjustable roller lever actuator with 15° +/- 5° pretravel [1.1]
  • IP67 degree of protection for resistance against water and dust ingress
  • Single-pole, double-throw (SPST-NO + SPST-NC) double-break contact configuration
  • Standard G1/2 (PF1/2) threaded inlet for secure wiring integration
  • Stainless sintered roller for improved wear and corrosion resistance
  • Exceptional mechanical durability rated up to 15,000,000 operations

Versatile SPDT contacts rated for up to 10A at 250VAC or 6A at 30VDC, capable of directly switching varied industrial control circuits and power loads.

Industrial Applications

1. Automated Conveyor Workpiece Detection

Utilized in material handling setups to count, index, or detect heavy raw materials as they pass along conveyor tracks. The adjustable roller lever facilitates precise mounting distance adjustments.

Problem Solved

Provides dependable physical actuation with a 13.34 N operating force, ensuring only intended heavy targets trigger the switch while avoiding false positives from lightweight debris or vibration.

2. Overhead Crane Hoist Over-travel Protection

Serves as a rugged end-of-travel limit stop on gantry or overhead cranes. The limit switch identifies the physical limit of the hoist to halt motors securely.

Problem Solved

The switch's 70° minimum overtravel safely absorbs the mechanical momentum of the crane hoist deceleration after actuation, preventing mechanical shearing or damage to the sensor housing.

3. Machine Tool Access Guard Interlocking

Detects the physical position of large industrial access doors or heavy machine tool guards, ensuring moving machinery cannot operate unless barriers are fully closed.

Problem Solved

Its heavy-duty 10A 250VAC rated contacts allow the switch to directly control power contactors, simplifying the safety circuit without requiring intermediary low-voltage relays.
