Retro-reflective This page 40 page Retro-reflective Limited-reflective Transparent Object Detection Retro-reflective Fiber Units are ideal for detecting transparent objects. The light beam passes through the object twice, this model interrupts light more than Through-beam model. Excellent detection performance with transparent films. (E32-LR11NP + E39-RP1) The specially designed filter eliminates undesirable light, which allows significantly more light to be interrupted for stable detection of films.
Attenuation 11% High Attenuation Attenuation 20% Interrupted light level 18% Interrupted light level 80% Before Using E32-LR11NP High Attenuation Low Attenuation Dramatically increases attenuation by cutting distorted light caused by double refraction.

Function) Note 1. * This effect may not be as strong for some films. Check suitability beforehand.
Objects with a high reflection factor may cause the Fiber Sensor to detect reflected light as incident light. Also, stable detection may not be possible for transparent objects. Check suitability beforehand. The following mode names and response times apply to the modes given in the Sensing distance column. [E3X-ZV] GIGA: Giga-power mode (16 ms), HS: High-speed mode (250 μs), ST: Standard mode (1 ms), and SHS: Super-high-speed mode (50 μs) [E3NX-FA] GIGA: Giga-power mode (16 ms), HS: High-speed mode (250 μs), ST: Standard mode (1 ms), and SHS:
Super-high-speed mode (30 μs) The values for the minimum sensing object are reference values that indicate values obtained in standard mode with the sensing distance and sensitivity set to the optimum values. The first value is for the E3X-ZV and the second value is for the E3NX-FA. The sensing distances for the E3NX-FA are values for E3NX-FA @ devices. The distance for E3NX-FAH @ infrared models varies. The E3X-HD Series offers the same sensing distance as the E3X-ZV. 2. 3. 4. 5.
