GENERAL INFORMATION FOR INDUCTIVE PROXIMITY SENSOR 1. Inductive Proximity Sensor Inductive Proximity Switches operate by using an L/C resonant oscillator which generates, with the aid of a coil located in the open pot core, a high frequency alternating electromagnetic field. This field emerges from the active face of the switch. When an electrically conductive material (for example a steel plate) moves into the electromagnetic field, an induced eddy current occurs. This eddy current extracts energy from the L/C resonant circuit in the switch, and produces a reduction in the oscillation amplitude....

GENERAL INFORMATION FOR INDUCTIVE PROXIMITY SENSOR Shielded construction includes a metal band which surrounds the ferrite Non-shielded sensors do not have this metal band, therefore they core and coil arrangement. This helps to direct the electro-magnetic can be side sensitive. field to the front of the sensor. Shielded Sensor Non-shielded Sensor 5. Sensor response curve (See Fig.3) Hystersis is the travel of the target between the "switch-on" point and the "switch-off" point. This distance is required to allow the switch to properly detect the target, and reduces the possibility of false trips....

GENERAL INFORMATION FOR INDUCTIVE PROXIMITY SENSOR 7. Mounting for normal operating distance Because of possible interference of the electromagnetic fields generated by the oscillators, minimum spacing is required between adjacent or opposing "active surfaces" of proximity switches. The "active surface " may be flush with the metal in which the switch is mounted, (see figure "Shielded Mounting"). The "active surface" must have a free zone in which no metal is present, (see figure "Non-shielded Mounting".). Y value is shown as the Table 5. When mounting proximity switches in this manner where...

GENERAL INFORMATION FOR INDUCTIVE PROXIMITY SENSOR If continuous curent flowing through the load Is less than 10mA, the proximity switch will malfunction. Connect the bleeder resistor parallel to the load in order to increase the current flowing through the load to more than 10mA. This allows the SCR in the circuit to operate reliably, and decrease the remaining voltage across the load. bleeder resistor Variation in sensing distance for successive operations under specified conditions (specified sensing range, temperature at 23±5"C, humidity £90%, specified operating voltage, circyle is 8 hours)....

GENERAL INFORMATION FOR INDUCTIVE PROXIMITY SENSOR DC NPN output proximity switches consist of the following circuit (Fig.9). In N.O. operation, with no sensing, the transistor is in the OFF mode. When sensing, the load current passes through the transistor. In N.C. operation, the function is opposite. In N.O. operation, as the load current passes 200mA (capacitive version over 300mA), the load short circuit protection is activated. Remarks: Voltage drop <1V, it is tested in the max. load current, 200mA. Capacitive Proximity Switch is tested in 300mA. SHORT CIRCUIT 22. DC 2 wire proximity switch...
