E3ZM-V Specifications 2

*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 highpressure 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.
