OPB200 series infrared slotted switches provide an LED-sensor pair separated by a 0.200 (W) x 0.320 (D)-in. slot. The device's phototransistor output switches from on to off when an opaque object is ...

A slotted infrared optical switch for non-contact interruptive object sensing, the OPB420 Series switch includes an infrared LED and phototransistor with both devices residing in a right-angle plastic ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

the OPB920xZ Series Photologic slotted optical switch comes in a right angle package and consists of an infrared LED mounted on the tower and a Photologic sensor mounted on the base.

The device actuates when an object interruptsthe infrared LED packaged in the device, which can be driven with dc forward current up to 50 ma. Maximum reverse dc voltage is 5 V, and maximum power ...

The switch has an infrared LED and phototransistor housed in a right-angle plastic package that lets an opaque object block the light beam from multiple directions, including the X, Y, and Z axes.
