At a glance
• Sensor and cable have a rugged Teflon coating for use in the most aggressive
environments
• Suitable for use in the food and beverage industry
• Sensing range adjustment via teach wire
• Background suppression and through-beam types available
Your benefits
• High cost savings since neither the sensor nor the cable requires a protective
barrier
• Excellent sensor characteristics recognize critical, dark objects
• Less machine downtime due to a long sensor life that withstands even the most
aggressive cleaning and process agents
