EZ11 Liquid detection photoelectric sensors - PANASONIC

Liquid detection photoelectric sensors from the EZ11 series by Panasonic are specialized optoelectronic devices designed to detect the presence or absence of liquids in industrial processes. These sensors operate on the principle of light refraction and reflection, utilizing a focused infrared beam that changes its path when in contact with a liquid medium. Key technical specifications include a sensing distance typically up to 10 mm for water-based liquids, response times as fast as 1 ms, and an IP67 protection rating for harsh environments. The EZ11 series offers both NPN and PNP output configurations, with a supply voltage range of 12-24 VDC. These sensors are compact, featuring a cylindrical M8 or M12 threaded housing for easy mounting in tight spaces, and are available with cable or connector variants for flexible integration.

These sensors are primarily deployed in industrial automation systems for monitoring liquid levels, detecting leaks, or controlling fill processes. Common applications include coolant level monitoring in CNC machines, water presence detection in HVAC systems, and liquid interface detection in chemical processing plants. They are also used in packaging machinery to ensure proper filling of containers, in wastewater treatment for sump pump control, and in food and beverage production for ingredient level sensing. The EZ11 series is particularly suited for environments where non-contact detection is required to avoid contamination or corrosion.

The EZ11 series includes several subcategories based on sensing method and output type. Key article codes include EZ11-D10 (diffuse reflective type for liquid detection), EZ11-T10 (through-beam type for transparent liquid detection), and EZ11-R10 (retro-reflective type for opaque liquids). The code structure typically follows the pattern EZ11-[sensing type][sensing distance], where 'D' denotes diffuse, 'T' denotes through-beam, and 'R' denotes retro-reflective. Additional variants include EZ11-D10-N (NPN output) and EZ11-D10-P (PNP output), with cable lengths of 2m or 5m. These sensors are available with M8 or M12 connectors for quick installation.
