The side looking packages are for use in PC board mounted slotted switches or as an easy mount PC board interrupter. Notes: (1) RMA flux is recommended. Duration can be extended to 10 sec. max. when flow soldering. A max. of 20 grams force may be applied to the leads when soldering. (2) Derate linearly 1.33 mW/o C above 25o C. (3) Ee(APT) is a measurement of the average apertured radiant incidence upon a sensing area 0.180" (4.57 mm) in diameter perpendicular to and centered on the mechanical axis of the lens and 0.653" (16.6 mm) from the lens tip. Ee(APT) is not necessarily uniform within the measured area.
