Slotted Switches from PerkinElmer

Standard transmissive (slotted) switches - this series of interrupter type optical switches combines an infrared emitting diode (IRED) with an NPN phototransistor. Units are available in two different case styles, either a one piece, sealed, IR transmitting plastic case (VTL11 and VTL13 series), or an opaque case (VTL23 series). Options also include apertures over detector and/or emitter, and either PC board mount leads or 12 inch, #26 AWG leads (VTL13 sereis only).

Reflective optical switches combine an infrared-emitting diode (IRED) with an NPN phototransistor or photodarlington in a one-piece, sealed, IR-transmitting case. Sealed construction improves resistance to moisture and debris. Units are available with PC-board mounting leads (VTR16D1), 12-inch, 26 AWG flying leads (VTR17D1) or 5.5-inch, 26 AWG flying leads (VTR24F1). Please contact Pacer for data sheets.
