Oil-resistant, Robust, Compact Photoelectric Sensor Photoelectric Sensor for the Automotive and Machine Tool Industries • Oil-resistant, rugged body made of stainless steel. • Spot visibility improved to as far as 1 m away. Product lineup includes Through-beam Models with Orange Spot. • Product lineup includes M12 Smartclick pre-wired connector models. Refer to Safety Precautions on page 11. For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Features A Sensor with Stainless Steel Housing That's Strong, Compact, and Easy to Use! Resists Oils and Coolants Industry Top The E3ZM-C features a simple shape and structure, and yet provides IP67 protection and oil resistance (oil resistant to OMRON in-house standard). This performance exceeds any previous models from OMRON. The protective structure eliminates the need for screws to hold a cover, so there are no worries about loose screws leading to liquid penetration. The compact, easy-to-use E3ZM-C with built-in amplifier is ideal for oily environments. Comparison Example for Oil Resistance (Test Oil: Gryton 1700D) And the model number is laser-marked on the housing so it's always readable when the time comes to order maintenance parts.

Perfectly Reliable Detection Performance and Connection Method Visible Beam. Long-distance Operation Even in Dusty, Dirty Environments E3ZM-CT@2B Br ight Orange Spot The E3ZM-CT@2B uses a bright orange LED to generate a spot that's visible 1 m away. And the sensing distance of 20 m provides more leeway in detection (response time: 2 ms). It all adds up to a more visible, more dependable worksite. World's Smallest, and Yet Robust Patent Pending The E3ZM-C is the same compact size as the E3Z, making it the smallest square metal photoelectric sensor in the world (according to OMRON investigation)....
