1. For information on the P-opaquing function, refer to Data Sheet.
 2. If a sensing object such as a glass plate is being used, the light reception level may not be attenuated sufficiently.
 In the following cases, be sure to test operation sufficiently under actual operating conditions.
 1) If the temperature varies more than 5°C
 2) If the Sensor or Reflector moves due to vibration
 3.Do not bend the cable in temperatures of −25°C or lower.
 4. This value applies when an E39-RP1 Reflector is used.
 The ambient operating temperature range when the E39-RSP1 or E39-RP37 is used is -25 to 55°C.
 5. 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.
 *6.Mounting Brackets must be ordered separately.
