A wide gap optical emitter-sensor pair from TT electronics Optek Technology operates efficiently over distances up to 12 inches in harsh industrial environments.
The RoHS-compliant, panel mount parts fit in a 12mm (0.473 inch) hole. “The emitter and sensor housings are color-coded and the components are easily panel mounted with standard connector fittings," says Roland Chapa, assemblies business unit director at Optek of Carrollton, TX, during the introduction at National Manufacturing Week.The 935 nm LED has a maximum continuous forward DC current of 40mA, a reverse voltage of 2V, and power dissipation of 100mW. The on-state collector current for the phototransistor is 1.8mA or higher. Its operating temperature is -40C to +85C. Pricing starts at $16.98 each in quantities of 1,000. Customized versions are available.
An optical emitter-sensor pair from Optek works efficiently over distances up to a foot.
Being in an incubator can be analogous to shopping in a “big box retailer.” You can find many things you need under one roof along with moral support to sustain and move your startup to a successful launch.
Scientists at four major universities in Europe have released a joint paper describing the use of light to put active materials into motion and to control that motion, producing lifelike mechanisms that may or may not contain living organisms, but can produce useful work.
