Optical flag sensors added to TTI portfolio
The OPB850A family of optical flag sensors from TT Electronics – Optek are now available from distributor TTI.
This sensor is targeted for the medical and industrial applications, manufacturing automation, safety and security equipment.
The OPB850A switch has a NPN phototransistor coupled with a 940 nm gallium arsenide infrared emitting diode in a moulded plastic housing.
Each OPB850-1Z has a Rbe phototransistor coupled with an 880 nm gallium arsenide infrared emitting diode in a moulded plastic housing.
An actuated lever arm flag interrupts the light beam, which switches the transistor output between states that can readily drive logic gates. These devices are designed to replace conventional mechanical limit switches where long life and reliability are critical.
The switches are designed to easily snap mount into a 0.036 inch (0.914 mm) 20 gage thick material with a rectangular opening of 0.315-inch x 0.472-inch (8.0 mm x 12.0 mm).
Minor differences exist in the package between the OPB850A and OPB850-1Z.
The cable exits the package in different locations.
