The Control is a PID controller that makes any solenoid valve "intelligent", the choice of solenoid valve depending on the user's application (from among the 601, Posiflow, Preciflow solenoid valves etc), and on the installation, which may be in a critical environment.
The Control can control 2 loops in the same manufacturing process, whether they are open, closed or double (cascaded). For instance:
- In an open loop: the Control adjusts the valve's pressure or flow rate (without a sensor) by measuring the feedback value.
- In a closed loop: the Control continuously compares the set pressure or flow with the set point thanks to a signal emitted by the sensor. The benefits? Very precise control (hysteresis of 1%) that reacts to external interference
- In a double loop (with 2 sensors): the first loop adjusts the valve's pressure or flow for optimum control, while the second loop returns the signal of the relevant feedback value (pressure, position, force etc). Because the process's response time is integrated into the control process as a whole, the latter is more stable.

These electromagnetic holding magnets are used in electrically operated independent clamping devices to hold open fire protection doors and exits. The doors are held open either in a fixed position or in a manually adjustable angle until they are electrically released.
Magnets for EX applications with ATEX certification are available.
Size: 42 - 70 mm with quality control
Holding force: 300 - 1568 N by quality controlled
goods
Rated torque: 1.5 - 3.0

DESCRIPTION AND OPERATION
Assembled on a fixed part, these suction cups ensure the magnetic maintenance of the doors via a reinforcing plate. The release is obtained: by electric drive remotely cut of the supply voltage for the models with lack of tension powering for the models with emission of current manually via a pushbutton (models with lack of tension). The return to the position “maintenance” is obtained while bringing back the door in the initial position.

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.

AZM range solenoid interlocks, operating in combination with control elements of a machine, e.g. fail-safe standstill monitors or fail-safe delay timers, ensure that sliding, hinged and removable guarding devices, such as grids , hoods or doors, cannot be opened until hazardous conditions (e.g. running-down movements) have come to an end.
These solenoid interlocks are also used for cases in which the opening of a guarding device represents a non-permissible intrusion in a production process.
In combination with AES and AZR range safety monitoring modules, the AZM range solenoid interlocks achieve Control Category 3 or 4 to EN 954-1, subject to suitable circuit arrangements. Examples of circuits for solenoid interlocks are shown in the Schmersal Control Circuit and Applications Handbook.
Schmersal make both standard and AS-i Safety at Work solenoid interlocks.

Magsafe is Smartscan’s latest innovation in machine safety. An electro-magnetic interlocking system for controlling personnel access through the gates and doors set within the perimeter safety fencing or screens surrounding potentially hazardous machinery.
The key design element in Magsafe was to lock the door using magnetic force rather than by mechanical means and to remove the problems that plague existing gate locks due to liquid and dirt exposure in combination with the rigors of daily operation. This causes fatigue and leads to mechanical failure of the product. The ability to withstand harsh industrial environments such as water, dust and corrosive liquids Magsafe is the perfect solution for most guard locking applications.
In addition to this Smartscan has applied its safety light curtain technology background to the safety gate interlocking market by providing a system control unit which continuously monitors the on and off state of the magnets. This ensures the system detects when the gate is open and when it is closed. Only when the gate is closed and the magnetic locking force applied, will the control system allow machine operation.

Designed to control access to the dangerous or protected areas, this device is installed in any kind of door, gate, housing, and permits remote unlocking from a distance.
Equipped with a forced opening contact, it permits the detection when the access is closed again.

SAFETY HANDLES P-KUBE LINE
Thanks to the experience in the field of safety switches, Pizzato Elettrica introduces an innovative line of safety handles called P-KUBE.
This new line represents the answer to practical issues that the operators have with the application of safety switches on machinery guards, like the ease of installation, the precise mechanical movements of the guard, the occurrence of critical environmental conditions, the presence of inattentive staff.
Unlike other products on the market, the basic principle of this series provides that the operator can enter and exit the danger zone with simple and natural movements by avoiding the locks to bolt. Its special design and materials allow the safety handle to be used in heavy applications or with sturdy protections.
The safety handles P-KUBE line distinguishes itself by the following main features:
- Easy installation and easy functioning: to open or close the door there are only intuitive actions needed.
- Handle provided with a self-centering sturdy metal pin in order to have the alignment between the jamb and the door: this device works also as a door mechanical stop.
- Possibility to assemble it on swing and sliding doors.
- Possibility to adjust the handle on 3 different axis through slotted brackets.
- Optional Lock-out device with padlocks to avoid the unwanted or accidental closing of the protection by the insertion of the actuator in the switch.
- Compatible with switch FD series with separate actuator and switch FG series with solenoid.

IDEM has launched The Kobra 'Hygiecam' KL3-SS , the world's first Solenoid Locking Tongue Interlock Switch in a fully Stainless Steel 316 housing. The switch has a mirror polished finish and is designed to cope with the rigorous high pressure hose cleaning demands of food and beverage manufacturing industries.
The KL3-SS is a compact, slimline locking switch designed to fit to all general applications.
The housings are IP69K rated and provide guard locking for medium to heavy duty guards (up to 3000N.).
The head is rotable to provide 8 actuator entry positions and all fittings including the actuators are made from Stainless Steel 316 to provide tough mechanical and environmental durability.
The switch is released by applying power to the solenoid after the machine is stopped.
A uniquely designed mechanism means that 2 sets of positively driven contacts are provided to monitor the actuator position and the solenoid status independently.
4NC Safety and 2NO auxiliary circuits are provided plus there are 2 LED's to provide independent diagnostics for the solenoid status and the actuator lock status.
