DICTATOR provides complete hold open systems for hazardous areas
They comprise explosion-proof smoke and heat detectors, door operators and the electromagnets. They comply with the requirements for group II products and can be installed in all zone 1 and 2 areas (according to VDE 0165). The explosion proof magnets are encapsulated (EEX m). Two series are available: with ex-proof connection box or with connection cable. The standard length of the cable is 2 m, but it can be delivered in the length required on site. The holding force of the magnets is either 550 N or 145N. The integrated release pin eliminates any remanence after switching off the power supply of the magnets, ensuring that the magnets always releases the door. All ex-proof magnets are equipped with diodes and polarity protection.
The DICTATOR ex-proof magnets have been tested both according to EN 1155:2005 for hold-open systems and the ATEX directive by the Physikalisch-Technische Bundesanstalt Braunschweig (certificates PTB 03 ATEX 2174 X and PTB 03 ATEX N060).
In addition to the ex-proof magnets DICTATOR also provides a large range of electromagnets for hold-open systems, that comply with the EN 1155:2005 and are approved for the use in hold-open systems. |

DESCRIPTION AND OPERATION
Gone up on a fixed part, these suction cups ensure
the magnetic maintenance of the doors by l’ intermediary
d’ a reinforcing plate.
The release is obtained:
by electric drive remotely
cut of the tension d’ food for
models with lack of tension
powering for the models
with emission of current
manually by l’ intermediary d’ a button
push rod (models with lack of tension).
The return to the position “ maintien” s’ obtains in
bringing back the door in the initial position. |

| Mencom Corporation is a worldwide supplier of DIN Solenoid Valve Connectors. Product line includes over molded connectors, field wireable connectors, and quick disconnect connectors in form A, form B, Industry Standard form B, form C, and Industry Standard form C. |
|
| The pre-wired and overmolded mPm valve Junior Timer connectors offer an economical alternative to hard wiring and mate with industry standard Junior Timer connector interfaces on solenoids and other mobile hydraulics devices and other harsh environment applications. The Junior Timer connectors are also available with surge suppression circuitry that extends the life of the coil and control circuitry. LED indication is built into the connector head for easy identification of system status. With an IP65 environmental rating, the Junior Timer provides protection in harsh and demanding environments. Plus the cable locking clip protects the connection in high vibration applications. |
|
| The line of mPm DIN connectors is designed to reduce the number of components making them easier to assemble and with fewer parts to stock. They provide repeatable, unsurpassed IP67 sealing performance using an external nut over the cable. Traditional Form A and B connectors require three different styles for PG07, PG09 and PG11. However the external nut accepts a wider range of cables from 4mm to 9mm, reducing the number of parts from 3 to 1. The new generation of DIN connectors is available in our complete range of field attachable sizes including Form A, B and C. |

MAGDOS LT is a solenoid-driven diaphragm pump with a state of the art microprocessor-controlled electronic.
The electronic provides power to the pump drive depending on the system´s pressure requirements thus reducing power consumption, noise level and heat generation. Due to the reduced heat generation MAGDOS LT operates at ambient temperatures of up to 45°C (113°F) depending on the chemical resistance of the wetted end material.
This dosing pump is available for a capacity range of up to 6 l/h and a maximum pressure of 6 to 16 bar. A flexible pressure adjustment is possible.
Double-ball check valves ensure high accuracy even at smallest flow rates.
MAGDOS LT solenoid-driven dosing pumps are especially suitable for water treatment and applications in the process industry. Due to the hermetically sealed design they are suitable for toxic and aggressive media.

Electromagnet is a type of magnet in which the magnetic field is produced by the flow of an electric current through the coil. The magnetic field disappears when the current ceases.
As a current is passed through the coil, small magnetic regions within the material, called magnetic domains, align with the applied field, causing the magnetic field strength to increase. As the current is increased, all of the domains eventually become aligned, a condition called saturation.
The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be rapidly manipulated over a wide range by controlling the amount of electric current. However, a continuous supply of electrical energy is required to maintain the field.
In applications where a variable magnetic field is not required, permanent magnets are generally superior. Additionally, permanent magnets can be manufactured to produce stronger fields than electromagnets of similar size.
Electromagnets are used in many situations where a rapidly or easily variable magnetic field is desired. Many of these applications involve deflection of charged particle beams; the cathode ray tube and mass spectrometer fall into this category.
Popular uses: linear motor, electric motor, circuit-breakers, electromagnet brakes, electromagnet clutches, metal lifter, magnetic separators, and more. |

These industrial holding magnets are units with an electromagnetic
holding system without an armature that is an open magnetic
circle for the holding of ferro magnetic parts.
The greatest holding force is dependant on the surface roughness
and component thickness.
Devices with permanent magnets and rectangular holding magnets are also available.
Size: 15 - 250 mm diameter
Max. holding force: 36 - 30000 N
(please note catalogue indications)
Rated torque: 1.4 - 90 W |
