These will convert this signal into a speed display, into analogue or data values, or use it for automatic length control. · Providing 1000 pulses per meter, thus resulting in fast response and high resolution of control. · Speed range from zero up to 3000 m/min. · Easy installation, prepared to use a supporting rod, thus resting on the surface by its natural weight. · Protection grade IP54 for use in a non aggressive environment. Connection By plug-in socket at the rear end. Fits our ready made signal cables L3A22 BO to all our units for permanent installation, available with any required length. Alternatively, the connector Bi4F/01 may be used. Pin Nos: (1) = supply (2) = open (spare for 2nd trace, if provided) (3) = common zero (4) = signal To connect to our portables use ready cable L3A25BP. Specifications Maximum Speed 1200 m/min with model A1L04B200 3000 m/min with model A1L05B500 Resolution 1000 pulses per meter Accuracy ± 0.5 % (clean wheels presumed) Allow. Temperature 0 … + 50 °C (30… 125 °F) Output square wave pulse (1 trace only) level = supply minus 2 volts. Load up to 20 ma Supply + 10… 30 v DC / 20 ma + load Dimensions Model No A1L04B200 A1L05B500 wheel circumference 200 ± 1mm 500 ± 2 mm wheel diameter ˜ 63,7 mm ˜ 159,1 mm outer wheel distance 70 mm 136 mm required support rod Ø 20 mm 20 mm adjustable distance from web to supporting rod 120 …310 mm 230..420mm Positioning Wheel should rest on a supporting surface by its own weight, and be pulled (not pushed) by the moving surface. Ordering information Model No (above) plus required cable length (or plug only). For use with the hand-held tachometer C118 add suffix -5V to model No to mark the special 5 volts supply necessary. wheel pulse transmitter A1L05B500
