3) All values valid for 23°C ambient temperature with no pre-energization if not noted
otherwise. Refer to diagram for values at other temperatures.
4) Requires external coil economization that must start 100-300ms after coil activation.
Avoid repetitive switching. Minimum clamp voltage 60V (see circuit recommendation).
5) Valid over ambient temperature range from -40°C to +85°C. Values include the specified
shock and vibration resistance.
6) 3.6Ω coil is switched off internally max. 250ms after pull-in. Demagnetization voltage
is clamped at 60V. No external coil suppression necessary. External coil suppression
could reduce switching capability. Please contact TE Connectivity for details.
