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.

And the model number is laser-marked on the housing so it’s always readable when the time comes to order maintenance parts.

The compact, easy-to-use E3ZM-C with built-in amplifier is ideal for oily environments.

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.

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).

The SUS316L housing makes it robust, and removes all worries of the coating coming off.

These Connectors match the XS5 Connectors released from August 2006, which reduce wiring work.
They eliminate the troublesome need to control torque when tightening connectors, and remove worries about screws loosening due to vibration.

Use the E3ZM-T/-R/-D/-LS in food processing or beverage filling applications where cleaners or disinfectants are present.

*1. A deviation of ±2 mm (typical value) can be handled for combinations of white, yellow, and black. Refer to page 7 for the detection capabilities for other colors.
*2. Mark Sensor output switching:
When teaching, specify the ON color first and the OFF color second.
*3. Do not bend the cable in temperatures of −25°C or lower.
*4. IP69K Degree of Protection Specification
IP69K is a protection standard against high temperature and high-pressure water defined in the German standard DIN 40050, Part 9. The test piece is sprayed with water at 80°C at a water pressure of 80 to 100 BAR using a specified nozzle shape at a rate of 14 to 16 liters/min. The distance between the test piece and nozzle is 10 to 15 cm, and water is sprayed horizontally for 30 seconds each at 0°, 30°, 60°, and 90° while rotating the test piece on a horizontal plane.
