Speed Rotational Speed Sensor FUA 919-3 • Optical probe for measurements of rotational speed, designed as retroreflective photoelectric sensor for photoelectric detection of rotational speeds. • For evaluation of the pulses, the tachometer probe is equipped with a specific frequency meter module that calculates the number of revolutions per minute from the time period between two pulses. A stable read-out is achieved by averaging over a minimum of 500 ms. • Easy application: A reflective adhesive tape is attached to the moving part and the probe is aligned with it. For function control purposes a yellow signal lamp at the rear side of the probe will be on when the reflective adhesive tape is recognised. • To increase the operation reliability the sensitivity can be adjusted through a potentiometer. Technical Data: Measuring range: Switching frequency: Ambient temperature: Storage temperature: Protection system: No-load current: Supply voltage: Device connector M12x1 including socket M12x1, angled, with 1.5 meters cable and ALMEMO® connector Material: Housing: Lens opening: brass, nickel plated, PMMA Dimensions: Diameter: length: Detection range: Reference object: adjustable with potentiometers Detectable object: Light spot diameter: 11/2019 • We reserve the right to make technical changes. Limit for foreign light: Display switching status: Extension cable, 1 meter long Extension cable, 2 meters long Rotational Speed Sensor up to 30000rpm max., incl. 5 reflective adhesive tapes Connecting cable 1.5m long with ALMEMO® connector DAkkS / DKD or factory calibration KU90xx rotational speed for digital sensor (see chapter Calibration certificates).
