P.1552~ PHOTO PHOTO MEASURE panasonic.net/id/pidsx/global Sensing objects can be detected at a constant using the triple beam sensing method Hardly affected by color Adjustable range reflective type sensor can detect white or black object at the same. Therefore, the sensor can even detect individual objects that are mixed with black objects or objects of various colors that were hard for the diffuse reflective type sensor to detect. Hardly affected by background Adjustable range reflective type sensor dose not detect objects beyond the set range. For this reason, malfunction does not occur even if there are moving machines or people passing by in the background. separated CX-4 CY-1 EX-1 EX-2 EX-3 EX-4 CX-44 EQ-3 EQ-5 -LS2 RT-61 However, when the background is specular, it may be necessary to change the angle of the sensor. ENVIRONAL RESISTANCE Insusceptible to contamination on lens Adjustable range reflective type sensor detects the by the angle, not by the light receiving intensity. Even if the lens surface is soiled by dust or any powdery material, there is little variation of sensing range. In addition, the sensor stably detects approaching objects at a fixed because the is sensed by the angle of received light. MOUNTING / SIZE Compact and slim size A small size of W32 H32 D12.6 mm W1.26 H1.26 D.496 in has been achieved for the 4 mm in / 2 mm in sensing range type due to the built in amplifier. In addition, you can mount the sensor both vertically and horizontally by diagonal mounting. VARIETIES Visible light type and low hysteresis type are available Visible light type Beam axis alignment can be performed by looking at the spot light. Low hysteresis type Hysteresis between the ON and OFF status has been reduced by half (compared to conventional model). Detection precision has been further improved!

Triple Beam Adjustable Range Reflective Photoelectric SERIES 338 APPLICATIONS Object presence detection The sensor detects objects that are being conveyed with almost no influence from background objects. Conveyor line Black tire sensing Roller conveyor Glossary (Performance overview of the triple beam adjustable range reflective type) Sensing (rated) For the triple beam adjustable range reflective type, the maximum to operate stably with a standard sensing object is shown. Setting range (optimum) For the triple beam adjustable range reflective type, the range between the maximum and minimum setting to operate stably with a standard sensing object is shown. When used beyond this range, there will be a non-detectable area near the sensor. There will also be insufficient light intensity on the far side of the sensor. This will result in unstable sensing. So when setting the sensor, use it within the optimum setting range. Black tire Detecting the remaining amount of roll sheets Even if roll sheet colors are changed, the sensor can detect them at almost the same. Stability Indicator The series uses PSD for light receiving elements and since sensing is based on the position of the entering beam and not its intensity, the output corresponds to. The stability indicator displays the marginal degree of the incident light intensity. So take note that the by which the indicator lights on/off varies depending on the reflectance of the sensing object, as shown in the diagram below. Also, do not use the sensor when the stability indicator lights off (Unstable light received condition).

In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country. Case grounding method and insulation mounting bracket The series has an internal circuit that is completely insulated from the enclosure (floating method). An exclusive insulation mounting bracket is available in order to improve the anti-noise quality in case there are devices that produce high-frequency noise close to the sensor and the place where the sensor is mounted is an electric conductor (such as metal).

Refer to p.1552~ for general precautions. Performing direct-grounding between the enclosure and circuit V will improve the anti-noise quality. Contact our office if you would like to special-order the direct-grounding type that has the enclosure and circuit V connected beforehand.
