Product Advantages and Features
1. Extremely Compact, Dual-Channel in One Unit:
· The key feature is the integration of two independent sensor elements into a cylindrical housing measuring just Ø11 mm. This saves a significant amount of installation space and is a perfect replacement for traditional setups requiring two separate sensors.
2. High Precision and Performance:
· Features a very small light spot and extremely fast response time, enabling reliable detection of very small or fast-moving objects.
3. Easy and Flexible Installation:
· Standard M5 threading allows for easy installation in tight spaces.
· The rotatable M5 connector lets users adjust the cable outlet direction to suit wiring needs, greatly simplifying installation and maintenance and preventing cable twisting.
4. High Reliability and Environmental Resistance:
· The housing is typically made of high-quality V4A stainless steel (1.4404 / 316L), offering excellent resistance to corrosion, acids, alkalis, and cleaning processes, making it ideal for harsh industrial environments.
· A high protection rating (IP67) ensures the sensor is protected against dust ingress and temporary immersion, suitable for damp and dusty environments.
5. Visible Red Light:
· Uses visible red light, facilitating precise alignment of the transmitter and receiver during installation and setup.
6. Short-Circuit and Reverse Polarity Protection:
· Built-in protection safeguards against damage from wiring errors or reverse power connection, enhancing durability and safety.
