Terminal connection Pin configuration

(Unit : mm)

■Features

(1) Employing a self-oscillating laser chip enables a compact

and low cost pick-up.

It eliminates the need for radio frequency modulation

circuit and related resistors/shields.

(2) Insert frame structure enables super-thin package(3.0mm

thickness)

(3) With built-in high speed response OPIC❇(MIN. 40MHz)

(4) With built-in beam splitter and diffraction grating

❇OPI C : (Optical IC) is a trademark of SHARP Corporation.

An OPIC consists of a light-detecting element

and a signal-processing circuit integrated onto a

single chip.
