ATTEND Unveils Rugged SIM Socket Series with IP67 & Anti-Vibration Design

ATTEND, a leading provider of advanced connectivity solutions, introduces the 115U Series Push-Pull SIM Socket lineup, offering compact, vibration-resistant, and IP67-capable SIM card interfaces for demanding embedded and portable applications. Engineered with a secure tray-based Push-Pull mechanism, the series supports Nano SIM, Dual Nano SIM, and stacked Nano SIM + Micro SD configurations, delivering long-term mechanical reliability and flexible integration for industrial automation, IoT, and transportation systems.

Traditional SIM card connectors often face challenges under mechanical shock or vibration. The 115U Series addresses this with a lockable Push-Pull design that prevents unintentional card ejection while ensuring accurate card alignment and smooth insertion. With EN 60721-3-5 Class 5M3 compliance, and a wide –40°C to +105°C operating range, the sockets are optimized for rugged environments. Optional waterproof trays enable IP67-level protection when sealed. In addition, all models support multiple tray lengths (16.5mm to 23.9mm) with standard and waterproof variants, allowing flexible system integration based on space constraints.

“Our engineering team optimized the 115U Series to deliver stable SIM performance in environments subject to high shock and vibration,” said Leon Hung, Product Manager at ATTEND. “We tested all configurations across full –40°C to +105°C ranges, and when paired with the waterproof trays, the design reliably meets IP67 sealing and long-term mechanical durability requirements.”
