OBSOLETE - ML 24 V DTM/ATM Solenoid

A magnetic latching solenoid (ML) is a bi-stable power switch that uses a magnetic latching mechanism to maintain its state (ON or OFF) without requiring continuous coil power.

Low current draw: It consumes very little current in stable state (less than 13mA at 25°C), reducing battery drain.Reliability: Silver alloy contacts ensure reliable switching of voltage loads.Energy efficiency: Current draw is significant only during state change (less than 4A for 20 ms).

This BLUE SEA solenoid is designed to operate at a nominal voltage of 24V DC. The maximum permissible voltage for the contact circuit is 32V DC.

The current draw of this solenoid is very low. In steady state (ON or OFF), it is less than 13 mA at 25°C. During state change (ON to OFF or vice versa), the draw is less than 4 A for approximately 20 milliseconds.

Yes, this solenoid is IP66 certified. This means it is fully protected against dust and powerful water jets, making it suitable for demanding marine environments.

Silver-alloy contacts provide high reliability for switching loads under voltage. They ensure better conductivity and increased resistance to wear and corrosion, which is critical for durability and performance in high-current applications.

No, this specific model (PN 7719 / 7719B / 7719100) is a solenoid without a manual override. The remote battery switch (RBS) models in the ML series with manual override are PN 7713 / 7717.

The solenoid has an LED output that allows remote indication of its state. A double-blinking ON-OFF LED can also signal a desynchronization between the remote command and the relay state.

This solenoid has a mechanical endurance of 100,000 cycles. Its hot-switching current capacity is 150A at 24V DC for 10,000 cycles.

This solenoid is CE certified and meets the requirements for protection against external ignition per ISO 8846 and SAE J1171 standards. It is also rated IP66 for water and dust protection.

The solenoid should be installed as close as possible to the battery bank it is intended to control. This minimizes voltage drop and optimizes system performance.

For remote control of this solenoid, a single-pole double-throw switch (SPDT) or a single-pole single-throw switch (SPST) is recommended. An SPDT switch provides better immunity against accidental switching if the switch terminals become wet.

The power terminals are tinned copper studs sized 3/8"-16 (M10). The recommended maximum tightening torque for these studs is 15.8 N•m (140 in-lb) to ensure optimal and secure electrical connection.

Before starting the installation, it is imperative to disconnect all negative battery connections. Additionally, all unused control wires must be carefully isolated from each other and from any accidental contact, for example using heat-shrink tubing or insulating tape, to prevent malfunctions.

The terminals of this solenoid are designed for 3/8" (M10) ring terminals. The clearance for the terminal ring diameter is 1.18" (30 mm).

Recommended wire sizes depend on the current:

For 225A DC: 2/0 AWG (70 mm²)

For 300A DC: 4/0 AWG (120 mm²)

For 500A DC: 2x 4/0 AWG (2x 120 mm²)

It is critical to select the appropriate wire size for the expected maximum load.

To avoid malfunctions, all unused control wires must be carefully insulated. External contact or a short circuit between control wires can cause unexpected behavior of the solenoid.

No, this solenoid (PN 7719 / 7719B / 7719100) is specifically designed for 24V DC electrical systems. Its control circuit requires a voltage between 18V DC and 32V DC.

This solenoid model is compatible with Deutsch DTM series connectors. Requirements for the mating side are a DTM-04-6P receptacle, WM-6P locking sleeve, 1060-20-0122 contact pins, and 0413-204-2005 sealing plugs.

Yes, this solenoid from the ML series is designed to be used as a remote battery switch (RBS), allowing you to connect or disconnect a battery bank from a load, or to combine/isolate multiple battery banks.
