Excellent for intrinsically safe circuits and harsh environments
Cincinnati, OH – December 4, 2013 — Standex Electronics, a manufacturer of custom and standard reed switches, reed sensors, reed relays, and magnetics announces their new ATEX optocoupler for intrinsically safe circuits. The optocoupler series are tested and certified for extreme/harsh environments such as potentially explosive atmospheres so they will not become an ignition point when subjected to short circuits or adjacent component failures. Markets the optocouplers will benefit include, but are not limited to oil & gas production, refinery, fracking, bio energy, mining, geothermal, medical, test and measurement, and others.
Optocouplers are electronic components which use light waves to provide electrical isolation while transferring an electrical signal. Standex Electronics’s optocouplers have a number of different uses and applications, which include: control technology, network engineering, automation technology communication systems, measurement and data acquisition systems, control and connection equipment, and heating technology. Additional applications are counting systems, speed indication, rotation measurement, seismic instrumentation, temperature monitoring and measurement, and medical ESD protection.
The main features that the optocouplers offer are their galvanic separation between input and output circuits, analog & digital signal transfer is possible, there are marginal coupling capacities between input and output, only minor output delay times compared to relays, and they have a long life due to their nonabrasive mechanical wear. Their isolation resistance between input & output is up to 10e+13 Ω, their magnetic fields do not impact operation, a photodiode makes for very short cycle times (nanoseconds) with more than 10MHz possible, and there are input and output differences up to 20 KV. Also, Standex Electronics’s optocouplers are able to invert the output signal during transfer, there is a lifetime factor increased by a factor of 10 if the LED is used with less than 50% of the nominal current, and they are resistant against voltage drop.
