# SLOTTED SWITCH, TRANSISTOR ![Product image](https://novapart.co/image/farnell:2352217/) **URL**: https://novapart.co/products/OPB804../slotted-switch-transistor **SKU**: OPB804.. **Manufacturer**: TT ELECTRONICS / OPTEK TECHNOLOGY **Category**: Sensors & Transducers || Sensors || Photo Interrupters || Transmissive Photo Interrupters **Price**: €1.4300 **Stock**: 10+ **Lead Time**: 222 days (indicative) ## Specifications | Parameter | Value | |---|---| | Gap Width | 3.94mm | | Product Range | OPB804 Series | | Sensor Output | Phototransistor | | Aperture Width | 1.52mm | | Forward Voltage | 1.25V | | Sensor Mounting | Through Hole | | Forward Current If | 50mA | | Reverse Voltage Vr | 2V | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:2352217/) ## Slotted Optical Switch ## OPB804 ## **Features:** - Non-contact switch - PCB mount - Wide aperture - Opaque body to minimize sensitivity to ambient light ## **Description:** OPB804 is a non-contact optical switch with a NPN silicon phototransistor and infrared Light Emitting Diode (LED) which are mounted on opposite sides of a 0.155” ( 3.94 mm) wide slot. The device body is a single molded piece opaque plastic that reduces ambient light interference. A wide open aperture makes it versatile for general applications. LED emissions are near-infrared (850 – 940nm). ## **Applications:** - Non-contact object sensing - Assembly line automation - Machine automation - Equipment security - Machine safety **==> picture [484 x 63] intentionally omitted <==** **----- Start of picture text -----**

(2) Feature controlled at body. - (3) Cathode lead may be shorter. (4) RMA flux recommended. Highly activated water soluble fluxes may attack plastic. Recommend trial to verify application. (5) Maximum lead soldering temperature .060” [1.6mm] from case for 5 seconds with soldering iron. (6) Plastic is soluble in chlorinated hydrocarbons and ketones. Methanol or isopropanol are recommended as cleaning agents. (7) Derate linearly 1.67 mW/°C above 25° C. (8) All parameters tested using pulse techniques. (9) Do not connect input diode directly to a voltage source without an external current limiting resistor. (10) Do not apply reverse voltage to LED. LED will be a 0V in reverse voltage and draw current as if a short.
