WHAT’S NEW Packaging gets angles right
Providing design engineers a flexible optical devicewithmultiple output configurations, TT electronics Optek Technology has developed a Photologic slotted optical switch in a right angle package. Designated the OPB920xZ Series, the non-contact switch consists of an infrared LEDmounted on the tower and a Photologic sensormounted on the base of a right angle shaped package. The OPB920 Series digital switches complement Optek's proven OPB420 Series analog slotted optical switches,
