Omron Limit Switch

This limit switch is a miniature safety device designed for industrial automation and control panels, providing mechanical actuation and electrical switching for position detection and interlock functions. It is intended for indoor machine and equipment installations where a compact, safety‑oriented actuator is required and meets recognised North American safety standards.

• Direct‑opening mechanism ensures positive NC contact separation under deposit conditions
• IP67 enclosure for protection against dust and temporary immersion
• Electrical durability to 500,000 operations at 3A, 250V AC for resistive loads
• Mechanical life rated to 15 million operations for long service cycles
• Rated insulation voltage of 300V supporting medium‑voltage control circuits
• Suitable for microloads down to 1mA at 5V DC for sensitive signal detection

• Suitable for limit sensing on conveyor position control systems
• Ideal for safety interlocks on access doors and guards in machinery
• Used with hoist and lift controls conforming to EN115 and EN81‑1 directives
• Can be used for status detection in PLC‑based automation panels
• Used for replacement installations where CSA or UL approvals are required

Multiple built‑in contact forms are available including snap‑action 1NC/1NO and 2NC, and slow‑action variants including 2NC/1NO and 3NC to suit different control logic requirements.

Use a 10 A fuse type gI or gG conforming to IEC 269 in series as a short‑circuit protection device.

It operates from −30°C to 70°C with no icing and up to 95% relative humidity, but should not be used outdoors or where hazardous gases are present.
