Simple effet linear electromagnet
“Simple-effect linear” electromagnets are available in two main categories:
Main characteristics of simple-effect linear electromagnets :
- Designed in accordance with standards EN 9100, ISO 9001 and ISO 14001
- Design eliminating any risk of the mobile armature jamming.
- Guide bearings for increased return and lifespan
- All our coils are protected against vibrations and environmental stresses
A few examples of simple-effect linear electromagnet control applications :
- flaps (vents, sorting, switching)
- security (triggers, valves, distributors)
- brakes or clutches
- various mechanisms (punching, keyboard testers)

Double effect linear electromagnet
Designed to produce the same force in both directions, double-effect linear electromagnets are available in three categories :
Bistable electromagnets are equipped with magnetic locking in two positions without consuming current.
Monostable electromagnets are equipped with magnetic locking in a single position without consuming current.
Reversible electromagnets are models without a neutral position, the stroke of which is performed alternately in both directions, from one end position to the other.
Main characteristics of Mecalectro double-effect linear electromagnets:
- Designed in accordance with standards EN 9100, ISO 9001 and ISO 14001
- All models are equipped with maintenance-free guide bearings
- Increased return and lifespan
- All our coils are protected against vibrations and environmental stresses
A few examples of double-effect linear electromagnet control applications :
- valves (1/4-turn or gate)
- sorting flaps
- brakes
- positioning (lever, guide wires, etc.)

Rotary electromagnets
Rotary electromagnets are mainly characterized by a magnetic force used by way of a ring. When energized, they produce a limited angular movement up to 95°.
Rotary electromagnets
Main characteristics of Mecalectro rotary electromagnets:
- Designed in accordance with standards EN 9100, ISO 9001 and ISO 14001
- Movements by direct attack, thus minimizing some problems due to bulk and mechanical links
- Can accept a return spring
A few examples of rotary electromagnet control applications :
- switching flaps
- laser beam deviation
- measurement sweep contacts
- signalling

Proportional action electromagnets
(linear or rotary)
Proportional action electromagnets offer two possibilities :
- Stroke proportional to the current
- Production of a force proportional to the current for a given position
Proportional action electromagnets
Main characteristics of Mecalectro proportional action electromagnets :
- Designed in accordance with standards EN 9100, ISO 9001 and ISO 14001
- Electronic power supply and servocontrol
A few examples of proportional action electromagnet control applications :
- Diesel motors
- pressure regulators or valves
- flaps
- metering

Operation of control electromagnets
Presented in a fixed magnetic circuit, the copper coil is crossed by an electrical current, causing a magnetic flux and thus generating an attraction force that allows the mobile core to move. This remains in the bonded position as long as the coil is energized. When the power is lost, the core returns to its initial position.
Pull action mode
In this “pull” mode, the magnetic field created by energizing the coil attracts the core into the magnetic circuit and thus moves the load or attached system. Without power, the mobile core returns to its original position under the effect of an exterior force (gravity, return spring, etc.).
Push action mode
In this “push” action mode, a system or load is pushed by a through rod fixed to the mobile core (opposite the pull side) when the coil is energized. Without power, and as in the previous case, the core returns to its original position under the effect of an external force (gravity, return spring, etc.).
This device ensures the mobile armature moves when energized and stays in position when not energized by magnetic locking (permanent magnet). It is unlocked by reversing the polarity of the power supply to the coil. The return of the mobile armature to its initial position must be ensured by external forces (a return spring may be supplied as an option).
The magnetic force depends on the electrical power of the electromagnet and the size of the product. The duty ratio is the relationship between the duration under power and the cycle time (2 mins, 5 mins or 10 mins), which varies depending on its size.
There are five standard duty ratios (100%, 40%, 25%, 15% and 5%).
A 100% duty ratio indicates that the electromagnet can be energized indefinitely. Conversely, a 5% duty ratio indicates that the electromagnet, for which the reference cycle is 2 mins, can be energized for 6 seconds. It can be energized 114 seconds later under the same conditions.
The choice of electromagnet will depend on its environment, according to the various stresses :
- environmental : temperature, atmosphere, radiation, etc.
- mechanical : vibration, acceleration, weight, volume, etc.
- electrical : voltage, power (duty ratios), etc.
