MAXIMUM ELECTRICAL CHARACTERISTICS AND PROTECTION OF MAGNETIC DETECTOR (REED SWITCH)
Max. switching current : 100mA
For inductive loads (valves, contactors, ...), external protection is required to avoid damage caused by switch-off voltage peaks. Use
freewheeling diode, transil diode, varistor or similar.
PARTICULAR APPLICATIONS (valid for all models)
• Detectors used for direct control of incandescent lamps:
The capacity specifi ed on the lamp is based on its resistance when hot. When switched on, the resistance of the cold lamp is very low. Therefore,
the current rises quickly and may exceed the reed switch rating. Allowance should therefore be made for the real power of the cold lamp.
• With leads longer than 10 m, a 200 Ω resistor must be fi tted in series with the detector to reduce the capacitive effect caused by the wiring.
REED SWITCH CONNECTION : 4 possibilities
30 mm
Mounting recommendation:
Do not subject the detector's power supply cable to damaging traction / torsion during its service life.
