Specifications:
The FAMILY D - DS 46 solenoid by C.E.I. srl is designed for intermittent duty with a rated voltage of 12 V DC or 24 V DC. It has a pull current of 27 A for 12 V and 13 A for 24 V. The solenoid features a stroke of 26 mm and a starting force of 7 Kg. It operates within an ambient temperature range of -40°C to 120°C and weighs 0.74 Kg. The windings are insulated to class H (180°C).

Force Variation:
The force variation coefficient is dependent on ambient temperature, affecting performance across a range of 25°C to 125°C.

Versions and Options:
Available in pull action (D46) and pull-push action (DS46) versions, with options for different voltages, circuits, brackets, and optional springs. Electrical connections are standard cables.

Operation:
The solenoids are used to stop diesel engines by actuating the fuel supply lever. They are energized only during the stop phase to cut off fuel flow. Due to high operating power, the energized time should not exceed one minute, with sufficient cooling time between cycles.

Diagrams:
Force-stroke diagrams illustrate the relationship between force (in Kg) and stroke (in mm), with a maximum force of 7 Kg (68 Newtons).

Internal Springs:
Two types of internal springs are available: 5M1 with a wire diameter of 1 Kg (0.700 Kg) and 5M2 with a wire diameter of 1.25 Kg (1.100 Kg).

Electrical Circuits:
The solenoid's electrical connection is not polarity-dependent. It is designed for intermittent duty in diesel engines, with accessories available for M6 thread connections.

Application Example:
The solenoid is used for engine shutdown by energizing the solenoid, which moves the shutdown lever to the end-of-stroke position.
