• Speed sensors with integrated control • 3 wires - d.c. • Connector output M12 x 1 General Features: These sensors allow to control with extremely high precision the rotation of a toothed wheel or reference marks, switching off the load or giving an alarm in case the speed goes down the minimum threshold. Thanks to the extremely wide measuring range they can be even used to control repetitive operations, signalling in case of unavoided stops. Further delays or other special functions are implementable upon specific request. The output is protected against connection mistakes, overvoltages on lines, and short circuit of the load. The connection is possible with a 4 wires M12x1 connector which must be ordered separately. Technical data: • Working voltage: 10 ÷ 30 Vdc • Max ripple: 10% • No-load supply current: <15 mA • Rated operational current (Ie): 200 mA • Voltage drop: < 1,5 V • Switching hysteresis (H): <10% Sn • Repeat accuracy (R ): < 2% Sn • Maximum detectable interval (between two pulses): 2 min • Detectable start-up time (T1): 0 ÷1 min (default 2 sec.) • Temperature range: - 20 ÷ + 70°C • Max thermal drift of sensing distance Sn: ±10% • Degree of protection: IP67 • Status indicator: yellow LED = out ON; frequency over the threshold • Protected against short-circuit and overload • Electromagnetic compatibility (EMC) according to EN60947-5-2 • Shock and vibration resistance according to EN60068-2-27 e EN60068-2-6 Materials: • Housing 8 mm: stainless steel • Housing 12 - 18 - 30 mm: nickel plated brass • Sensing face: plastic
