PX-SB1

PHOTOELECTRIC SENSORS PX-2 SERIES CY Long Range & Wide Area Photoelectric Sensor Amplifier Built-in Conforming to EMC Directive Ideal sensing area with very little null zone Compact size for space-saving The advanced optical system of the PX-2 series reduces the null zones in front of an automatic guided vehicle (AGV). The null zones at the sides are further minimized if auxiliary sensors which can be easily mounted with connectors are used. (For PX-24, PX-24ES, PX-23ES and PX-26) Its size is half of a conventional model, and the attached cable orientation is freely adjustable. Hence, it can also fit in a small AGV. Moreover, sensitivity adjustment can be done on the front face.

Further, in case of PX-24ES and PX-23ES, the sensing areas can also be selected with external signals. PX-26 has a long sensing range of 5 m 16.404 ft. Even on a high-speed AGV, it can detect an object quite early so that slowing down and stopping are smooth.

Sleep function Automatic interference prevention function External sensitivity adjustment The sensor can be put into the sleep (stand-by) condition when it is not used and can be restored to operating condition by an external signal. Consequently battery is conserved as the power consumption is reduced to 1/7. One PX-2 sensor can simultaneously receive beams from 25 Nos. of other PX-2 sensors without resulting in any interference. Even if AGVs are facing each other, the PX-2 sensor on one AGV reliably detects the other AGVs. Hence, it can be safely used even at a place where several AGVs are moving. The sensitivity of the sensor can be adjusted, within the range set by the manual adjuster, by an external input. For PX-24, PX-24ES, PX-23ES and PX-26 ( ) Sleep condition   A.G.V.

PX-SB1 Sensitivity adjustment CY Step Emission adjuster Supplementary sensing adjustment with sensitivity adjuster Operation Remove the front cap. • If the sensor receives beam emitted from the main sensor, you will not be able to adjust the sensing range at shorter distance. In such case, follow the below procedures to modify the sensitivity. Front cap Turn the emission adjuster counterclockwise fully. 2 A 3 Receiving adjuster 4 A Seal Light receiving indicator lights on. 8 object Emission adjuster Move the object out and find out the point b where the sensor turns on again with some background by turning the adjuster further clockwise. Make sure that the clearance between point @ and point b is more than one graduation on the scale of the adjuster. B B Light receiving indicator lights up. PM Put the front cap back on the sensor. MAX. Attune the emission adjuster again so as to obtain your expecting sensing range in the manner of the procedure on the above table. 0 Make sure that the sensor turns on only with ownbeam reflection by moving the object in all possible way. If not yet, decrease the sensitivity a little. A (Note 1): If the receiving adjuster is fully minimized, the sensor goes into insensitive condition. Front cap Put the front cap back on the sensor. PM2 Micro 7 NX5 B Notes: 1) Turn the adjuster gradually with the attached adjusting screwdriver. Over-turning may cause the adjuster to fail. Notes: 2) Angle the sensor not to make the superfluous sensing area that beam emitted from the main sensor enters into the sensor. Notes: 3) When two PX-SB1s are used, do the above job individually. DIMENSIONS (Unit: mm in) PX-2 Position the receiving adjuster at the intermediate point b between the minimum point and the present point @. MIN. Make sure that the sensor turns on only where the object is in the set area, no the other area that the sensor receives beam emitted from the main sensor by moving the object in all possible way. 6 A 9 Turn the adjuster back to the point @. 5 Operation Peel the seal off the sensor at the top. Place an object at the position where you expect the sensor to detect it. Turn the emission adjuster clockwise up to the point @ where the sensor turns on. Make sure that the sensor detects only the object, not your hand adjusting.
