Notes:
These relays contain bias magnets. Correct coil polarity must be observed.
Coil suppression diode is recommended for proper operation. Correct coil polarity must be observed.

Dot stamped on top of relay refers to pin #1 location. E-pin indicates Electrostatic shield pin. Unused pins omitted.
Pin numbers for reference only.
