MAXIMUM ELECTRICAL CHARACTERISTICS AND PROTECTION OF MAGNETIC DETECTOR (MR)
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.

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
V
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.
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.
