Notes:
1
Consult factory for life expectancy at other switching
 loads. 9090 series contact resistance >0.5W defines
 end of life or failure to open.
2
Optional diode is connected to pin #2 (+) and pin #3(-).
 Correct coil polarity must be observed.
3
9000 series part numbers designated with Form B
 contacts, these relays contain bias magnets.
 Correct coil polarity must be observed.
4
Consists of 20V Zener-diode and 1N1002 diode
 in series, connected in parallel with coil.

Environmental Ratings
Storage Temp:-35°C to +100°C; Operating Temp:-20°C to +85°C
Solder Temp: 270°C max; 10 sec. max
The operate and release voltage and the coil resistance are
specified at 25°C.  These values vary by approximately
0.4%/°C as the ambient temperature varies.
Vibration:  20 G’s to 2000 Hz;  Shock:  50 G’s
