Photointerrupters(Transmissive)
K DNH OESI
DG-290
DIMENSIONS
The DG°©290 carrying a unique hysteresis transistor (BAMBIT)developed by KODENSHI CORP.facililates d i g i t a l output bymeans of two leads.This digital p h o t o i n t e r r u p t e r , b e c a u s e of its ultra°© compact size,requires little space.
(Unit : mm)
