Residual Magnetism Latching Solenoid

This solenoid example is a linear on-off design with a built-in latching feature that holds the solenoid in position using residual magnetism.

This latching solenoid is a linear on-off design with a built in latching feature that holds the solenoid in the energized position. The solenoid’s latching feature does not require the use of continuous current or permanent magnets to hold in the selected position. Strokes and latching force are flexible depending upon solenoid size.

Using Solenoids to Increase Safety in Hybrid Cars

A manufacturer sought a solution for disconnecting the battery of a hybrid car during an accident, without the possibility of the battery connecting again. TLX designed a custom latching solenoid that used residual magnetism instead of a permanent magnet; meaning once the solenoid unlatched, it would not re-latch without applying power.

Our engineers begin by designing with 3D CAD and performing electromagnetic and fluid dynamic analysis with state-of-the-art finite element analysis software. Every design is engineered and tested in our lab to meet our customers’ specifications.

Increased Performance

Precise control with high accuracy through tighter tolerances. Reducing friction and inefficiencies provides extremely low hysteresis.

Lighter Weight

Multiple variables in the design and manufacturing process are optimized to reduce overall weight and size of the solenoid or valve.

Minimized Footprint

Custom solenoids can be designed to utilize the best control scheme for your application, resulting in a minimized footprint.

Limited Power Consumption

Latching technology in solenoid and valve design minimizes overall power consumption.

Extreme Environments

Can be designed to meet extreme environments that include moisture, dirt/dust, vibration and/or extreme temperature requirements.

Built-in Safety

Failsafe modes are designed into solenoids and valves utilizing integrated electronic controls.
