The that the Photomicrosensor does not wobble. mounting strength of the Photomicrosensor will decrease if the • When mounting the Photomicrosensor to a molding with a hole, hole has burrs. make sure that the edges of the hole are sharp enough, • When mounting the Photomicrosensor to a panel with a hole otherwise the Photomicrosensor may fall out. opened by pressing, be sure to mount the Photomicrosensor on the pressing side of the panel. • The mounting strength of the Photomicrosensor will increase if the Photomicrosensor is mounted to a panel with a hole that is only a little larger than the size of the Photomicrosensor, in which case, however, it will be difficult to mount the Photomicrosensor to the panel. The mounting strength of the Photomicrosensor will decrease if the Photomicrosensor is mounted to a panel with a hole that is comparatively larger than the size of the Photomicrosensor, in which case, however, it will be easy to mount the Photomicrosensor to the panel. When mounting the Photomicrosensor to a panel, open an appropriate hole for the Photomicrosensor according to the application. 187 Output allowable dissipation Pc (mW) Output transistor Light interrupting plate
