H900 Gigabit Industrial 4G Router

Designed for M2M, vehicle, and security applications, the H900 offers multi-link redundancy through triple-link backup across cellular, wired, and WiFi connections. It includes five Gigabit Ethernet ports for multi-device concurrent connections and vehicle-grade protection compliant with ISO 7637-2, including ignition sensing for harsh mobile environments.

H685f/H685 Mini Embedded Series

Built for space-constrained integration projects, this series measures only 100×60×21mm, fitting inside kiosks and robots while combining Ethernet, serial (RS232/485), and DI/DO interfaces for a one-stop connectivity solution.

H820QO Outdoor IP68 Waterproof Router

An outdoor 4G CPE rated IP68, the H820QO allows shelter-free, direct pole mounting and includes built-in 14dBi high-gain antennas to improve signal reception in remote field areas.

M300/M400 Industrial 4G Modems

These plug-and-play modems provide serial transparent transmission, converting RS232/RS485 to 4G to enable rapid cloud migration for legacy PLCs and meters.

Technical Foundation Behind the Product Line

E-Lins' technical capabilities rest on 20 years of independent R&D in wireless data communication, with equipment online rates reported at ≥99.5%, a wide operating temperature range of -35°C to +75°C, 15KV ESD electrostatic protection, and 1.5KV electromagnetic isolation. The devices support advanced VPN protocols including WireGuard, IPsec, and OpenVPN, along with link self-healing mechanisms and hardware watchdog timers. On the platform side, the company supports TR-069, SNMP, SSH, and NMS cloud platforms for centralized management, alongside Modbus, TCP/IP, and industrial serial transparent transmission protocols.

ODM/OEM Manufacturing Credibility

A defining element of E-Lins' business model is its role as a long-term ODM/OEM manufacturing partner for Huawei, ZTE, Samsung, and LG. This tiered manufacturing credibility, built over 20 years, is paired with an in-house SMT factory and assembly lines in Shenzhen capable of producing tens of thousands of units monthly. The company holds ISO 9001 and ISO 14001 certifications, along with CE, FCC, RoHS, and UKCA compliance.
