Omron Limit Switch

This limit switch is a compact, industrial mechanical sensor designed to detect position changes and provide reliable switching for automation and control equipment. Engineered for environments where sealed performance matters, it offers multiple actuator styles and contact arrangements to suit safety and general-purpose roles. The product supports direct-opening mechanisms and can be installed with a variety of conduit or M12 connector options to simplify wiring and maintenance.

• IP67-rated sealing for protection against dust and temporary immersion
• Direct-opening NC contact for positive contact separation
• Mechanical durability of at least 15,000,000 operations
• Electrical durability up to 500,000 operations for 3A at 250 VAC
• Contact resistance maximum 25 mΩ for consistent signal integrity
• Operating temperature range −30°C to 70°C for wide ambient use

• Suitable for industrial conveyor end-of-travel detection
• Ideal for safety interlocks on access doors and guards
• Used with hoists and lifts requiring position feedback
• Can be used for machine-tool limit sensing in production lines
• Suitable for retrofitting older control panels as a replacement switch

The internal modules include snap-action and slow-action types with 1 NC/1 NO, 2 NC, 2 NC/1 NO, 3 NC and make-before-break variants to match different control logic requirements.

Use recommended connectors or conduit adaptors with correct seal packing and tighten to the specified torque

The switch meets AC and DC utilisation categories with rated currents such as 10A at 120 VAC and 3A at 240 VAC for typical switching loads

A direct-opening mechanism forces NC contacts apart via the plunger action so separation occurs even when metal transfer has occurred, preserving safety-oriented operation.

Avoid locations with explosive or corrosive gases, constant oil/water splashing or extreme condensation
