Slotted Optical Switch OPB202 Features: • • • • Opaque housing Inexpensive plastic housing 0.110” (2.79 mm) gap small profile slotted switch Customization available Product Photo Here Description: OPB202 consists of an infrared Light Emitting Diode (LED) and an NPN silicon phototransistor mounted on opposite sides of a 0.110 (2.79 mm) slot in an opaque plastic housing. Switching of the phototransistor occurs whenever an opaque object to light wave lengths between 400nm and 1100 nm passes through the slot. The lens on both the LED and phototransistor is 0.6” [1.5 mm] in diameter resulting in an equivalent aperture of 0.6” [1.5 mm]. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
