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
