MAXIMUM ELECTRICAL CHARACTERISTICS AND PROTECTION OF MAGNETIC DETECTOR (REED SWITCH)
R = 4 W resistor. Standard CCTU resistors code RP 59,
C = paper, polycarbonate or metallized mylar capacitor.
The user is responsible for supplying and assembling of
components.
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 re-
sistance 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 1000
Ω
resistor must be
fi tted in series with the detector to reduce the capacitive
effect caused by the wiring.
Note: The switching point
must remain within the limits
of the shaded area. Any ex-
cess voltage or power may
damage the detector.
Electrical protection
• Output protected against short-circuit as long as the output current is restricted to 0.1 A.
• Improper wire connection may prevent the detector from operating or even destroy it.
• It is recommended to install a protection diode (mounted in parallel) on an inductive load in spite of the internal protection.
