OMRON E3ZR-CR81D 2M Photoelectric Sensor

The OMRON E3ZR-CR81D 2M is a robust and reliable photoelectric sensor designed for demanding industrial environments. This sensor features a retro-reflective configuration with an MSR (Multi-Scan Reduction) function, ensuring stable detection by minimizing interference from ambient light. The sensor uses a red LED light at a wavelength of 660 nm, providing excellent visibility and accuracy.

Key Features and Benefits:

• Oil Resistance: Built with stainless steel housing, the E3ZR-CR81D 2M is highly resistant to cutting oil, making it ideal for use in machining and manufacturing environments where machinery lubricants are present.
• Durable Construction: The sensor's robust design withstands harsh conditions, while its IP67 and IP67G7 ratings ensure protection against dust and water, along with oil resistance.
• Retro-Reflective Capability: The sensor is designed for use with an oil-resistant reflector, allowing for a sensing distance of up to 2.5 meters.
• PNP Output and Dark-ON Operation: This model operates in Dark-ON mode with a PNP output, making it suitable for applications where objects need to be detected by the absence of light.
• Operating Temperature Range: The sensor operates effectively in temperatures ranging from -25°C to 55°C, ensuring reliability across various environmental conditions.
• Safety Features: Includes reversed power supply polarity protection, output short-circuit protection, and reversed output polarity protection to ensure safe operation.
