Ex magnetic sensors Ex RC M14 1W - 2m Material number: 1189237 (Material number old: 21433201) Directive for the protection of reed contacts
With unknown input currents, input capacitances we recommend the interposing of an interface relais. When using Finderrelais series 49, in the following you will find some proposals to protect the reed contact against overload.
Inductive load:
Inductive load at DC voltage
Inductive load at AC voltage S1
S1 +
coil voltage 24 VDC 24 VAC 230 VAC
serial resistor Rs
24 - 230V AC
27 Ohm 39 Ohm 330 Ohm / 0.6 W
RS
62 KOhm Additionally Fa.Finder recommends a parallel resistor for the 230V-type
Recovery diode e.g. 1N4007
24 - 250V DC

Due to the cable capacitances it is necessary to place the series resistors as near as possible to the reed contact, in general the next terminal point (junction box). Finder interface relais series 49 with modul series 99.80
RC network according to operating voltage
R C
Capacitive load, cable length more than 5m or connenction to process control system with capacitive input:
Current limiting at capacitive load
Current limiting at electronic timing relay
e.g. PLC, PCS and cable length > 5 m S1
