The OPB610 series Slotted Optical Switches consist of an infrared emitting diode and an NPN silicon phototransistor with an enhanced low current roll-off to improve contrast ratio and immunity to background irradiance. The switch consists of an infrared emitting diode and a PIN photodiode with a polysulfone housing that is opaque to visible light, but transmissive to infrared. The low tr/tf of the PIN photodiode is ideal for high-speed operation. The sensitivity to ambient radiation is minimized.
• Non-contact switching
