Product Features
1. Functions
1)Dual Sealing ProtectionIt serves as a sealing component for encoder mounting positions. The annular structure fits the gap between the encoder and the mounting base tightly. It blocks dust, moisture, oil stains, and other contaminants from entering the encoder interior. It protects the precision optical/electronic components of high-resolution encoders. It prevents external pollutants from affecting encoding accuracy or causing component damage. This protective performance meets the strict standards of
Electronic Device Seals and
Electronics Waterproof Parts for precision electronic equipment.
2)Integrated Circuit ConnectionThe integrally molded bifurcated structure extends the wires. It replaces the traditional "separate sealing ring + external wire" configuration. It serves as a conductive connection channel between the internal encoder circuit and external equipment. It also forms a seal at the wire exit point. It eliminates sealing gaps caused by separate wiring. It fixes the wire position. It prevents wire loosening or poor contact due to vibration and pulling.

2. Performance Characteristics
1)Sealing Stability of EPDM + Peroxide VulcanizationIt is made of EPDM and processed via peroxide vulcanization. This process achieves more uniform and dense crosslinking of EPDM molecules. It enhances the sealing fit and creep resistance of the rubber component. Combined with the 50°A medium-hardness setting, it retains sufficient elasticity. It adapts to minor tolerances of the mounting surface and fills sealing gaps tightly. It avoids long-term extrusion deformation caused by excessively low hardness. It maintains stable sealing performance over time. This stability meets the material standards of
Electronic Equipment Sealing Components and high-reliability electronic accessories.
2)Reliability of Integrated StructureThe wires and rubber component are integrally molded. There are no splicing gaps at the junction. This design eliminates sealing loopholes from separate wiring. It also strengthens the connection between wires and rubber. It enables resistance to vibration and slight pulling during industrial equipment operation. It reduces the risk of wire loosening and poor contact. It meets the requirements of high-resolution encoders for stable circuit connection.
3)Environmental AdaptabilityEPDM inherently offers excellent temperature resistance (adaptable to temperature variations from -40℃ to 120℃), aging resistance, and chemical resistance. Enhanced by peroxide vulcanization, it can withstand temperature and humidity fluctuations and mild oil contamination in industrial scenarios. No material hardening, embrittlement, or sealing failure occurs after long-term use. It matches the long service life requirements of high-resolution encoders. This adaptability meets the durability standards of Sealing Accessories for Electronic Devices in harsh working environments.
4)Structural AdaptabilityThe annular structure with mounting clamping grooves can match the installation dimensions of high-resolution encoders accurately. The 50°A hardness ensures easy assembly of the rubber component. It is not too hard to embed into the mounting position. It is not too soft to deform during assembly. It guarantees sealing and structural stability after installation. This precision is like the manufacturing standards of Electronic Sealing Components and high-precision electronic equipment accessories.

1)High-Resolution Encoder MatchingIt is suitable for installation sealing and circuit lead-out of various high-precision photoelectric/magnetoelectric encoders (e.g., servo motor encoders, robot joint encoders, precision machine tool encoders). It is especially applicable to high-precision encoding equipment with a resolution of ≥17 bits.
Industrial Automation EquipmentIt is used for encoders in industrial robots, CNC machine tools, automated production lines, etc. It adapts to vibration and temperature variation environments during equipment operation. It meets sealing protection requirements at the same time.
2)High-Protection Demand ScenariosIt is applicable to encoder applications requiring sealing protection in outdoor, humid, and dusty environments (e.g., high-precision encoders for outdoor security equipment, waterproof encoders for food processing equipment). The integrated sealing and wiring design improves the environmental adaptability of encoders.

4. Pain Point Solutions
1)Resolving the "Sealing + Wiring" ContradictionTraditional high-resolution encoders adopt the "separate sealing ring + external wire" method. It tends to form sealing gaps at wire exits. It leads to dust and moisture intrusion and damage to precision components. This wire-integrated sealing ring eliminates sealing loopholes from wiring through its "sealing component + wire integration" design. It satisfies the dual requirements of sealing and circuit connection.
2)Solving Wire Connection Stability IssuesHigh-resolution encoders are often used in industrial equipment with frequent vibration. Ordinary external wires are prone to loosening and poor contact due to vibration. It affects encoding signal transmission. The integrally molded wire structure of this product fixes the wire position. It improves the vibration resistance of wire connections. It ensures stable signal transmission.
3)Addressing Insufficient Durability of Ordinary SealsHigh-resolution encoders typically have a long service life. Seals made of ordinary materials/processes are prone to deformation and hardening due to temperature changes and aging. It results in sealing failure. The EPDM peroxide vulcanization + 50°A hardness design of this product enhances material aging resistance and deformation resistance. It matches the long service life requirements of encoders. It reduces maintenance and replacement frequency.
4)Meeting Adaptability Requirements of High-Precision ScenariosHigh-resolution encoders have strict requirements for installation gaps and circuit connection accuracy. Ordinary seals/wire connections cannot satisfy the tolerance and stability needs. The precise structural dimensions, stable sealing, and circuit connection performance of this product can meet the application requirements of high-precision encoding equipment. It avoids encoding accuracy degradation caused by sealing or connection issues.
