Notes:
1
Consult factory for life expectancy at other switching loads.
2
Model 2904, 2911 and 2920, pin #7 is tied to optional electrostatic
shield, pins #6 & #7 are tied to optional coaxial shield.
3
Model 2920 has Hg wet contacts - position sensitive, must
be mounted within 30° of vertical plane. See schematic.
4
Consist of 20V Zener-Diode and 1N4002 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
