From this Article:
Fail-safe Condition – it may be required that solenoid driven locking systems revert to a default condition (either open or closed) in the case of power failure. This may preclude the use of...
(Engineering and Scientific Software)
From this Article:
A Pick & Hold circuit regulates current applied to a solenoid or motor, applying high initial current (PICK) to develop high initial force/torque for fast response, then reducing this after a preset...
(Linear Actuators)
From this Article:
There are a number of applications where vibrating motion is required, for which simple solenoid actuators are not ideally suited, and for which moving coil actuators although technically suitable are...

From this Article:
The image below shows 4 different polepiece configurations for a solenoid. As the displacement increases moving from left to right, the magnetic reluctance (resistance to magnetic flux flow) is kept...
(Solenoids)
From this Article:
There are a number of different factors that can influence the choice of a linear solenoid or actuator; the goal of the selection process is to identify the least expensive device that will satisfy...
(Solenoids)
From this Article:
Device size is determined for the required force, displacement, and duty cycle from the tables below, more detailed force data is shown graphically in the datasheet for each solenoid. These charts...

From this Article:
When deciding on a rotary solenoid for an application, there are a number of factors to take into consideration: Size, torque, and angle of rotation are the basics, but it doesn't end there. This...
(Solenoids)
From this Article:
A PHu-50 module is required, with USB-Micro cable, and PC with programming Software PHprogrammer.exe V6.0+. Other than these items a load device is required, and Power Supply able to supply voltage...

From this Article:
Locking systems for railway carriage doors would be a good example of a distributed system, the actuators are distributed through the length of a train, with large voltage fluctuations possible and...
(Solenoids)
From this Article:
Pick and Hold is a technique for energising solenoids that maximises the force and speed achievable from a given device, and/or reduces heat dissipation and power consumption. The force or torque...

From this Article:
The PHu‐ANA adds to the capabilities of the basic PHu module with a clear graphical display of the excitation current waveform. It helps the user to optimise excitation conditions for a solenoid...
(Motors)
From this Article:
Solenoids and small actuator devices inherently have movement between parts, which requires a sliding or rolling support that may be susceptible to dust or moisture ingress. In many cases, solenoids...
(Solenoids)
From this Article:
The bistable rotary solenoid changes state with the application of a momentary pulse of electricity, and then remains in the changed state without power applied until a further pulse of reverse...
(Valves)
From this Article:
Pinch valves facilitate opening and closing the flow of liquid through a tube without any contact between the liquid and the valve itself. The tube is pinched between a fixed and a moving bar (pinch...
