Tips for choosing an Open frame Solenoid

The open frame type solenoid is a basic electrical appliance, known as the "King of Electrical Appliances". It has significantly improved the power of generators and plays a very important role in many fields of industry. The quality of open frame solenoid impact a great influence on Equipment or device . In order to ensure the applicability and make sure the quality of Open frame type solenoid fully application, do pay attention to the following point:

Part one: Open Frame Solenoid Features:

1.1 Fast Response: Solenoid switches can switch circuits within a few seconds, offering efficient and rapid starting capabilities.

1.2 Long Lifespan cycles: These kind of solenoid have a lifespan of millions of on/off operations.

1.3 High Reliability: open frame solenoid are highly reliable, ensuring stable operation over long periods without any failure. They are designed to withstand high currents and voltages, with contacts treated to resist arcing and abrasion, enhancing their durability.

1.4 Lightweight and Portable:  Open frame Solenoid are small and lightweight , making them easy to install and transport. This feature is advantageous in space-constrained environments and facilitates easy repair and replacement.

1.5 Electromagnetic Operation: Open frame Solenoid operates through electromagnetism, but powered by DC source or AC electricity.

1.6 Wide Voltage Range: They can function across a wide range of voltages, from low-voltage DC to high-voltage AC applications.

1.7  Compact Size: Open frame Solenoid  are typically small, making them suitable for applications with limited space.

1.8 Quick Response Time: They offer fast on/off switching, ideal for applications requiring rapid response times.

1.9 Low Power Consumption: Open Frame solenoid switches are energy-efficient, consuming minimal power.

2.0 Weather Resistant: Many solenoid switches are designed to withstand various weather conditions, making them suitable for outdoor use.

Part two : Open Frame Solenoid Structure

The main structure of open frame solenoid is composed of movable iron core, fixed iron core,built copper coil, yoke, carbon steel housing and cover, connected wire structure and other main components. The movable iron core is made by lathe machine, so structural samples can be made according to the custom specification.  It is no need making any mould and tool for it. The structure is simple along with easy operation.

Part Three :  Working principle

The characteristic of open frame solenoid is that it uses the magnetic flux leakage principle of the spiral tube/open frame shape housing, using a coil to generate a large magnetic force in a small space. The assembled solenoid coil is packaged in a metal iron tube and made of high magnetic permeability steel. In order to achieve a smaller size and weight and produce a greater attraction, a push or pull process is formed after it is energized. The design of the movable iron core uses an auxiliary magnetic circuit to increase the output power by 20% to 50%.

Part Four :  Output settings

4.1. Power/Stroke: The stroke refers to the distance between the sliding rod part of the frame type electromagnet and the position of the complete suction state. The frame type electromagnet will produce different forces at different strokes. Generally, the smaller of the stroke, the stronger of the force. The bigger power of the output and the bigger force.

 4.2. Cycle load: Cycle load = [power on time/(power on time and power off time)]*100. The open frame solenoid will get hot when connected to power, so the cycle load and power on time determine the open frame solenoid. Temperature rise, the temperature rise and working temperature of the frame solenoid determine the selection of the flame retardant grade of the frame electromagnet.

Part Five:  Input standards

5.1 Power supply and output power: Different input current wave forms determine the posture of the frame solenoid. In application, there are: AC/DC (constant voltage source/DC power supply/battery/dry battery//DC power generation machine/capacitor)/rectifier filter method, etc.

5.2 Diode rectifier: If the open frame solenoid powers by  alternating current, a rectifier needs to be used to convert the alternating current into direct current. The rectifier should be designed to meet the principle of single-band rectifier. If the working voltage of the frame-type solenoid driver is three times, the current and output power are similar to a proportional relationship within a certain range. When the output power reaches a certain level and the frame-type solenoid exceeds the magnetic saturation state, the power will no longer increase. In addition, the output power is proportional to the temperature rise.

Part Six : Environmental factors and service life

Environmental conditions and service life are factors that need to be considered when selecting or maintaining frame solenoid materials. Environmental factors include: temperature/humidity/electromagnetic field/electrostatic field/environmental pollution, corrosive gas/liquid or floating dust/vibration and vibration impact etc.

Part Seven:  Material/Component

 When selecting the materials for the open frame-type solenoid product parts, good materials will have good lifespan along with stable performance, and the quality materials will not change easily after long-term working. In addition, good materials are not enough for the processing dimensions and surface finish of the solenoid material. Good material processing accuracy and finish also have a great impact on the life of the open frame solenoid. Choose a good surface treatment process according to the performance of the product. It greatly improves the life of the open frame solenoid.

Summery  

To choose a suitable open frame-type solenoid for your equipment, you need to pay attention to the output power, power supply standards, environmental factors, environmental factors and service life. It is also necessary to choose good materials and pay attention to related processing techniques.

Customization: These kind of open frame solenoid  can be customized to meet specific application needs, including mounting options, contact configuration, and voltage range.
