OMRON E3ZR-CT81L 2M Photoelectric Sensor

The OMRON E3ZR-CT81L 2M is a high-performance, oil-resistant photoelectric sensor designed to withstand harsh environments, particularly those involving cutting oil. This through-beam sensor is part of the E3ZR-C lineup, known for its reliability and effectiveness in reducing failures caused by oil ingress.

Key Features:

• Sensing Method: Through-beam, requiring both an emitter and receiver, which are sold together as a set.
• Connection Method: Pre-wired with a standard 2-meter cable length. Optional 5-meter cable lengths are available.
• Sensing Distance: Up to 30 meters using red light.
• Operation Mode: Light ON mode, indicating the presence of an object when the beam is interrupted.
• Output Options: NPN output configuration.
• Safety and Protection: Features open-collector output with protection against reversed power supply polarity, output short-circuit, and reversed output polarity. It also includes mutual interference prevention.
• Housing and Material: The sensor housing is made of SUS316L stainless steel, ensuring durability, while the lens is crafted from oil-resistant methacrylate resin.
• Environmental Tolerance: Operates effectively in temperatures from -25°C to 55°C and humidity levels between 35% and 85%.
• Degree of Protection: IP67 and IP67G certified, providing resistance to dust and water ingress.

Unique Selling Points:

• Oil Resistance: Designed to operate effectively in environments where cutting oil is present, reducing downtime and increasing sensor lifespan.
• Reliability and Precision: Offers precise object detection, making it suitable for applications requiring accurate sensing.
• Compatibility and Versatility: Can be integrated into various industrial control systems due to its standard NPN output configuration.

Accessories and Compatibility:

• Reflector: Sold separately; the E39-R1R oil-resistant reflector is recommended for retro-reflective applications.
• Mounting Brackets: Available separately for secure installation.
• Connectors: Sensor I/O connectors (e.g., M12) must be ordered separately if needed.

Certifications and Compliance:

• Complies with OMRON's oil-resistant component evaluation standards.
• Meets IP67 and IP67G protection standards for dust and water resistance.
