Axial Fiber Optic Isolator
OP1270 Series
Features:
Opaque plastic housings
High noise immunity
Visible Red LED with Phototranisitor Output
0.05" (1.27 mm) lead spacing
Data Transfer through plastic fiber optic cable
RoHS
Description:
Each
OPI1270
consists of a visible Red LED and a Phototransistor sensor, which are housed in separate opaque molded
plastic housings and coupled by plastic fiber optic cable. The heavy-duty opaque housing shields the optical signal from dust,
making this series of devices ideal for dust contaminated environments.
The OPI1270 series are designed for applications that require high voltage isolation between input and output. Depending on
the length of the fiber optic cable, the emitter does not have to be optically in-line with the sensor.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more
information.

Notes:
1. RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering. A maximum 20 grams force
may be applied to the leads when soldering.
2. Derate linearly 1.33 mW/ C above 25 C.
3. Isolation voltage testing is required.
