OPB725A-18Z

Long Distance Reflective Switch OPB725 Features: • • • • Remote mounting in 18 mm hole 48” (122 cm) 26 AWG wired with mounting nuts Non-contact infrared switch Up to 24” or more reflective distance depending on object Description: OPB725 uses an Infrared LED and Photologic® sensor in a reflective switch configuration. The assembly is offered with a standard wire length of 48” [122 cm], and uses an opaque housing to reduce the sensor’s ambient light sensitivity. The emitter and sensor are protected by a window clear to near infrared wavelengths, providing a device that can operate in a dusty environment. The Photologic® sensor has an NPN Open-Collector output providing the user a device that can be used in a variety of applications. While an object is in the reflective path of the device, light from the LED will be reflected back to the housing irradiating the surface of the Photologic® sensor causing the output NPN transistor to turn “ON” to provide a “low” voltage output when connected to appropriate value pull-up resistor. When the Infrared light from the LED is not being reflected to the Photologic sensor, the output transistor turns “OFF,” minimizing the IC(ON) current, providing a “High” output. Custom electrical, cabling and connectors are available. Contact your local representative or OPTEK for more information. Applications: • • • • Non-contact reflective object sensor Assembly line automation Machine automation Equipment security • • • Door sensor Machine safety End of travel sensor Ordering Information Part Number OPB725A-18Z LED Peak Wavelength 850 nm Wire Length / Size 48" / 26 AWG Wire Pin Out Wire Color Red Black White Function Vcc Ground Inverted Open Collector DIMENSIONS ARE IN: [ MILLIMETERS] INCHES RoHS OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
