Optical axis Sensor edge (to post header) Center of sensing slot EE-SX461-P11 Sensor edge (2) The Photomicrosensor can be mounted to 0.8- to 1.6-mm-thick panels. Refer to the above mounting hole dimensions and open the mounting holes in the panel to which the Photomicrosensor will be mounted. Insert into the holes the Photomicrosensor’s mounting portions with a force of three to five kilograms but do not press in the Photomicrosensor at one time. The Photomicrosensor can be easily mounted by inserting the mounting portions halfway and then slowly pressing the Photomicrosensor onto the panel. There are two ways to dismount the Photomicrosensor. Refer to the following. Dismounting with Screwdriver Press the mounting hooks of the Photomicrosensor with a flat-blade screwdriver as shown in the following illustration and pull up the Photomicrosensor. Panel (1) (1) Pressed mounting holes are ideal for mounting the Photomicrosensor. When mounting the Photomicrosensor to a panel that has pressed mounting holes for the Photomicrosensor, be sure to mount the Photomicrosensor on the pressing side of the panel, otherwise it may be difficult to mount the Photomicrosensor and an insertion force of five to six kilograms may be required. When mounting the Photomicrosensor to a panel that has mounting holes opened by pressing, make sure that the mounting holes have no burrs, otherwise the lock mechanism of the Photomicrosensor will not work perfectly. After mounting the Photomicrosensor to a panel, be sure to check if the lock mechanism is working perfectly.
