High Performance Linear Solenoids

These square solenoids are used wherever large forces, short switching times, and high efficiency with limited installation space are required. They fulfill the special requirements when used in high voltage circuit breakers and railway door lockings as well as in general actuating functions in automation and medical engineering.

The High-Performance Solenoids are available in two sizes. Due to their modular design, the solenoids are available in different voltage, power and stroke variants.

LHP025 with edge dimensions of 25 mm

The mode of operation of the solenoid is based on the force exerted on ferromagnetic bodies in the magnetic field. Electromagnets transform electric energy into mechanical energy. Basically, the stroke movement takes place from the stroke starting position to the stroke end position (active direction of movement), while the armature reset is accomplished by external forces, e.g., by spring, weight or magnetic forces (passive direction of movement). The fast-acting solenoids are actuators in which the force of an electromagnetic field is used to perform a longitudinal movement. The stroke limitation can be set by hand for every application. The solenoids can be installed in any position, but the force transfer should be in the axial direction only.

Integrated return spring optional

In this product line, the reset can optionally be performed by an integrated return spring. The solenoid armature is reset to the starting position.

Lifts - especially if they are approved for passenger transport - must meet high safety requirements. To prevent uncontrolled movement of the cabin, a speed limiter is installed, which is controlled by two electromagnetic actuators.The integrated and TÜV-certified linear solenoids ensure a safe stop both in normal operation and in an emergency.

The reliable locking of automatic doors is an important aspect of the security concept of modern buildings. By using electromagnetic locking systems, you have the possibility of centrally controlling various doors and thus reacting flexibly to the requirements of the environment.

Tramways and railways are equipped with an emergency brake to bring the train to an immediate standstill in an emergency. Thus, the doors mustn’t open until the train has come to a complete stop. This is ensured by the new LHP050, which impresses with its high force combined with a compact and robust design and withstands the high requirements in railway engineering.

Linear Solenoids LHP key facts

Benefits at a glance

The LHP convinces with an unique high power density due to its FEM-simulated iron circuit in square design in combination with the optimal copper-iron ratio and its precise cone control.
The LHP with an edge dimension of 35mm achieves forces of 160 N.

Due to its high power density and square shape, the LHP linear solenoid is extremely compact.
This makes the LHP series a space-saving wonder for all applications where only limited installation space is available.

The square design of the LHP allows both front and side mounting.
Therefore, the linear solenoid can be easily integrated into different applications.

With switching times of less than 30ms, the LHP series is extremely dynamic.
This makes it suitable for use in time-critical applications, e.g. in energy technology.

The solid construction and its precise armature bearing make the LHP solenoid extremely wear-resistent and robust.
Depending on environmental influences, 10 million switching cycles can be achieved.

Due to the modular design of the LHP, numerous configurations can be realised with the same basis solenoid.
Different strokes, power and voltage variants, increased IP protection, connection technology, optional return spring & further attachments.
