Product Guide

Electromagnets, solenoids and solenoid valves play critical roles across a wide range of applications, from everyday household appliances and light- and heavy-duty industrial equipment to safety and security systems and emerging AI-driven automation technologies. Their diverse configurations and flexible designs allow product specifications to be precisely tailored to different application requirements, supporting high-precision and customized solutions.

Because these products serve such a broad range of applications, no single standard model can meet every application requirement. Selecting the most suitable product type and specifications from a wide range of options is essential to achieving the required performance, reliability, and application fit.

Solenoid Application & Selection Guide

Key Selection Factors for Solenoids

> Outline Dimensions
> Actuation Direction
> Stroke (Travel Distance of the Plunger)
> Pull-in Force (Magnetic Attraction)

Solenoid Dimensions

Confirm the available installation space within the mechanism (length / width / height).
Ensure sufficient clearance from surrounding components without interference for proper installation.

Solenoid Actuation Direction

Select the actuation type—push, pull, or rotary—based on the application requirements.
Confirm the plunger return mechanism when power is disconnected.(Integrated return spring / plunger self-weight / customer-side mechanical return mechanism)

Solenoid Stroke (Plunger Travel Distance)

Evaluate the required travel distance of the mechanism first to ensure sufficient stroke.

Solenoid Pull-in Force (Magnetic Attraction)

First, estimate the required stroke and the corresponding actuation force needed at that stroke within the application.
Based on the application’s operating frequency and duty cycle, appropriate coil parameters and solenoid specifications can then be determined.

02 Electrical Conditions & Thermal Management

> Power Supply Conditions & Duty Cycle
> Temperature Rise & Operating Temperature Limits

Power Supply Conditions & Duty Cycle

Confirm the power input type of the customer’s application (DC / AC / battery).
Verify whether current-limiting measures are in place to prevent the current from exceeding the design range.
Confirm the maximum energization time per cycle and operating frequency to prevent overheating or overloading.

Temperature Rise and Operating Temperature Limits

Solenoids generate heat during operation. As the coil or ambient temperature increases, the available actuation force decreases impacted by temperature rising.
The maximum operating temperature is determined by the insulation class of the materials chosen. Higher ambient temperatures reduce the allowable coil temperature rise. Selecting appropriate insulation materials can enable a higher insulation class and improve thermal performance.
The actual ambient temperature during equipment operation should be defined in advance.

Environmental & Protection Design

> Humidity, Dust & Protection Requirements
> Protection Ratings & Cost Considerations

Humidity, Dust & Protection Requirements

High-humidity environments require protection against moisture ingress and external corrosion.
High-dust environments require protection against dust ingress to maintain stable operation and service life.
Appropriate protection measures should be selected based on the specific environmental conditions.

Protection Rating and Cost Considerations

If the product is intended for use in harsh operating environments, customized features such as moisture resistance, dust protection, or corrosion resistance can be incorporated to enhance product performance and reliability.
It is recommended to define the environmental conditions and required protection rating in advance to optimize the design and control overall costs.
