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
