DESCRIPTION
The ISH 3-A is an optically coupled isolator, consisting of an infrared emitting diode with a minim separation
of 15mm between the emitter and a Schmitt trigger detector. They are mounted in a sealed package, and have
an operating temperature range of -40°C to +100°C with an isolation voltage of 11Kv.
Isocom Ltd supplies a multitude of plastic
optocouplers for all applications varying from
standard transistor optos through to Darlington and
Schmitt Trigger devices. It’s massive family of optos
vary in speed allowing maximum opportunity to
engineers worldwide.
All devices are performance guaranteed between -
40ºC and +100ºC and have completed rigorous
testing.
The Company's customers can be assured of our
commitment to stringent quality, reliability and
inspection standards, as demonstrated by our existing
approvals. Other customer specific options can also be
offered.
