ATTEND introduces 115U series rugged SIM card holder: IP67 waterproof and anti-vibration design leads the new standard of industrial connection

2025-09-11

ATTEND, the world's leading provider of connection solutions, recently announced the launch of a new 115U series Push-Pull SIM card connector product line. With its compact structure, excellent anti-vibration performance and IP67 protection capability, this series provides a reliable SIM card connection solution for demanding embedded and portable applications. The introduction of this innovative product will further meet the high requirements of industrial automation, Internet of Things and transportation systems for long-term mechanical reliability and flexible integration of connectors.


Break through traditional limitations and redefine rugged performance

Conventional SIM card connectors often face stability challenges in mechanical shock or vibration environments. The ATTEND 115U series completely solves this problem with a lockable Push-Pull mechanism, effectively preventing accidental card ejection, while ensuring precise card alignment and smooth insertion and removal experience. The series complies with EN 60721-3-5 Class 5M3, supports a wide operating temperature range of -40°C to 105°C, and is optimized for harsh environment applications. Through the choice of waterproof card tray option, IP67 protection level can also be achieved.


Diversified configurations to meet different integration needs

Available in Nano SIM, Dual Nano SIM and Stacked Nano SIM Micro SD, the 115U Series meets the needs of modern devices for multi-function integration. All models support multiple Cato lengths from 16.5mm to 23.9mm, including standard and waterproof versions, providing great flexibility for system integration under different space constraints. Its innovative tray system is also equipped with card detection and anti-reverse insertion functions, further improving the reliability of the system.

Leon Hung, ATTEND Product Manager, said: "Our engineering team has fully optimized the 115U series to ensure that it can still provide stable SIM performance in high shock and vibration environments. We tested all configurations over the full temperature range of -40°C to 105°C. When used with waterproof trays, the design reliably meets IP67 sealing requirements and long-term mechanical durability requirements."


Wide range of application areas

The outstanding characteristics of the 115U series make it ideal for many areas:

  • Industrial Internet of Things (IIoT) Devices

  • Portable Consumer Electronics

  • Wearable Technology Devices

  • Medical Equipment

  • Smart home automation system
