# Transmissive Photo Interrupter, Open Collector, Through Hole, 3.18 mm, 1.27 mm, 50 mA, 3 V ![Product image](https://novapart.co/image/farnell:1678624/) **URL**: https://novapart.co/products/OPB668N/transmissive-photo-interrupter-open-collector **SKU**: OPB668N **Manufacturer**: TT ELECTRONICS / OPTEK TECHNOLOGY **Category**: Sensors & Transducers || Sensors || Photo Interrupters || Transmissive Photo Interrupters **Price**: €1.4500 **Stock**: 10+ ## Specifications | Parameter | Value | |---|---| | Gap Width | 3.18mm | | Product Range | OPB668N Series | | Sensor Output | Open Collector | | Aperture Width | 1.27mm | | Forward Voltage | 1.6V | | Sensor Mounting | Through Hole | | Forward Current If | 50mA | | Reverse Voltage Vr | 3V | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:1678624/) **Photologic® Slotted Optical Switch OPB615, OPB616, OPB617, OPB618 Series OPB625, OPB626, OPB627, OPB628 Series OPB665, OPB666, OPB667, OPB668 (N and T Series)** ## **Features:** • Non-contact switching - PCBoard mounting Product Photo Here - Enhanced signal to noise ratio - Choice of four Logical output options ## **Description:** Each **OPB615** , **OPB625** and **OPB665** series slotted optical switch consists of an 890 nm, infrared Light Emitting Diode (LED) and a monolithic integrated circuit that incorporates a photodiode, a linear amplifier and a Schmitt trigger on a single silicon chip. **OPB665** offers two mounting options -- no tabs (N) or two tabs (T). All devices in this series exhibit performance over supply voltages ranging from 4.5 V to 16.0 V, and may be specified as Buffered or Inverted with 10 kW Pull-up or Open Collector output. Devices are also TTI/LSTTL compatible and can drive up to 10 TTL loads. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information. **==> picture [489 x 319] intentionally omitted <==** **----- Start of picture text -----**
