Reflective switch offers adjustable sensitivity
The OPB725A-18Z reflective switch with adjustable sensitivity uses an infrared LED and a logic output sensor in a reflective switch configuration, and features a reflective sensing distance of up to 24 in., depending on the object. It is ideal for use in applications that require feedback on the presence or absence of an object, such as vending machines, mail sorters, and conveyor belts.
The switch is tested to ensure detection of an 8 x 8-in. 90% diffuse reflective white card at a distance of 18 in. with the sensitivity set to maximum (clockwise rotation) by the trimpot, which is accessible through a 4.3-mm-diameter hole in the sensor body. It also features an 850-nm LED, and is offered with 48-in. 26-AWG wires with mounting nuts. Power dissipation is 250 mW, maximum collector voltage is 30 V, and collector dc current is 50 mA. Operating temperature ranges from 0° to 50°C. (From $15.44 ea/5,000 — 6 to 8 weeks ARO.)
