Panasonic EX-22A Photoelectric Sensor
The Panasonic EX-22A Photoelectric Sensor (Part Number: UEX22A) is a highly reliable photoelectric sensor designed to detect opaque, translucent, or transparent objects with a sensing range of 5 mm to 160 mm (0.197 to 6.299 inches). It operates effectively with white non-glossy paper (200 x 200 mm) as the detection object. This sensor provides an NPN open-collector transistor output, with a maximum sink current of 50 mA and short-circuit protection, ensuring safety and reliability in industrial applications.
With a response time of 0.5 ms or less, the EX-22A is ideal for high-speed operations. The sensor also comes with IP67 protection for dust and water resistance, making it highly durable in harsh environments. It features easy-to-use LED indicators: an orange LED to indicate output and a green LED for stability. The sensor is also equipped with a sensitivity adjuster for fine-tuning, ensuring optimal performance in different environments.
