Building your own optical switch can be a fun project, especially when using it in safety critical applications. But for those who want to be able to have a good night sleep knowing that their design will not fail, the OPB6xx is the device for you. The TT Electronics OPB6xx series are optical switches that combine an IR diode with a high-speed photodetector in a single molded plastic frame. The detector side of the OPB6xx has a maximum operating voltage of 24V, a maximum power dissipation of 200mW, and a maximum collector current of 30mA, while the infrared LED has a maximum forward voltage of 1.6V. The high-speed operation of the OPB6xx is fast enough for use in safety applications (providing adequate protection against unauthorized entry from unsuspecting ninjas), and the use of electrical isolation between the infrared LED and infrared photodiode is perfect for bridging low and high-voltage systems.
