Encapsulation enhances the durability of electromagnetic coil windings while adding a level of protection against water, dust, and other contaminants. Encapsulated coils also hold up much better to impacts, vibration, and general rough handling. Because of these numerous performance advantages, custom coil encapsulation is required in many of today’s electronics manufacturing applications.
Why Choose Encapsulated Coils for Your Custom Electronics and Devices?
Encapsulated coil windings offer three functional advantages:
- Encapsulated coils will better withstand wear, tear, and rough handling – the encapsulation gives the unit a more durable construction that resists tearing, binding, or kinking.
- Allows for the integration of a custom DIN connectors or other mating connector in a single unit with sturdy construction.
- Improved aesthetics for electronics, giving the end product a more premium feel and appearance.
The common materials for electromagnetic coil encapsulation include:
- Liquid Epoxy Encapsulants
- Other Thermoset Epoxy Materials and Resins
- Specialized Engineering Plastics and Materials
Specialized Encapsulated Coil Applications:
IP65 Rated Encapsulated Coil Windings
Many of today’s electronics and devices require an IP65 rating. This is the industry standard weatherproof rating for protection against water, dust, and ingress of other contaminants. Reliable coil encapsulation is one of the common ways to achieve IP65 rated electronics.
Potted Electronics/Cast Coils with Poured Epoxy
Encapsulated coil products also include potted electronics and cast coils with poured epoxy materials. These highly durable winding solutions are often utilized in MIL-spec products, defense components, industrial equipment, and other rugged applications with harsh operational conditions. In addition to general durability, potted/cast coil windings provide better longevity due to crack resistance. They also provide a performance advantage with an increased resistance to partial discharge.
Other Common Product Applications for Electromagnetic Coil Windings:
- Specialized aerospace coil windings with encapsulation to protect against extreme operational conditions.
- Encapsulated MIL-spec coil windings and defense industry electronics.
- Overmolded, encapsulated, and potted electronics for medical devices.
- Weather-resistant automotive electronics and solenoids.
- A wide range of IP65 rated consumer electronics devices including mobile electronics, wearable devices, and home appliances.
