EElink - TK418

The TK418 is a compact, IoT‑oriented GPS tracker designed for vehicle and light‑asset deployments and is Plaspy compatible out of the box. Built for broad cellular coverage with LTE Cat M1 and NB‑IoT as primary connectivity and GSM fallback, the TK418 delivers dependable real‑time tracking, rich telemetry and configurable safety features that fleet managers and integrators expect from a modern Plaspy compatible device.

Small but capable, the TK418 combines multi‑GNSS positioning, ACC (ignition) detection, crash and vibration alerts, and an optional relay for remote cut‑off (immobilizer) into a 89 × 37 × 12 mm housing. It integrates with telematics platforms via the EELINK protocol so you can start pairing location, events and sensor data with Plaspy for fleet management, anti‑theft response and operational reporting.

Key Highlights

• Plaspy compatible GPS tracker with LTE Cat M1 and NB‑IoT primary networks and GSM fallback for wide coverage.
• Multi‑GNSS support (GPS/BeiDou/GLONASS/Galileo/QZSS) for reliable position fixes in difficult environments.
• Real‑time tracking and telemetry including crash, acceleration/deceleration, vibration and overspeed alerts.
• ACC (ignition) detection plus optional relay for remote cut‑off to support immobilizer and anti‑theft strategies.
• Expandable interfaces (RS232/GPIO) and a customizable SOS port that can accept external battery, iButton or Bluetooth devices for flexible sensor integration.
• 140 mAh backup battery with cut‑off and low‑power alarms to maintain reporting and notify Plaspy of power events.
• Compact, lightweight form factor (46 g) suitable for covert installation in vehicles and assets.

How It Works with Plaspy

Integrating the TK418 with Plaspy provides continuous, actionable location and event data. The unit communicates position and telemetry over LTE Cat M1 or NB‑IoT and falls back to GSM when needed. Plaspy ingests EELINK protocol messages to create real‑time tracking views, alerts and historical reports used for fleet management and operational decision‑making.

• Real‑time location and telemetry updates (multi‑GNSS) for precise tracking on Plaspy maps.
• ACC/ignition status reporting to correlate vehicle on/off events and driver behavior.
• Crash, vibration, acceleration/deceleration and overspeed alerts forwarded to Plaspy for instant notifications and incident logging.
• Geofencing events generated on device or in Plaspy for perimeter alerts and route enforcement.
• Remote immobilizer support via the optional relay for anti‑theft actions initiated from Plaspy.
• External sensor integration (RS232/GPIO) to add telemetry such as fuel‑sensor inputs or door/alarm contacts into Plaspy dashboards.
• SOS port customization to connect an external battery, iButton or Bluetooth device — Plaspy can surface SOS events and associated sensor data.

Technical Overview

Use Cases

• Fleet management: continuous location, ignition state and driver event telemetry for route optimization and compliance reporting in Plaspy.
• Anti‑theft and immobilization: rapid immobilizer activation via optional relay combined with geofence and overspeed alerts to reduce vehicle theft risk.
• Driver safety and incident response: crash, vibration and SOS events forwarded to Plaspy for fast operator response and incident logging.
• Telemetry extension: integrate fuel sensors, door/alarm contacts or other serial/GPIO devices to centralize fuel monitoring and asset telemetry in Plaspy.
• Light asset tracking: discreet installation on trailers, equipment or small vehicles where compact size and NB‑IoT battery efficiency matter.

Why Choose This Tracker with Plaspy

When you need a Plaspy compatible GPS tracker that balances small size with robust connectivity and flexible I/O, the TK418 is a practical choice. Its LTE Cat M1/NB‑IoT connectivity reduces power and extends coverage in IoT deployments while GSM fallback keeps devices reachable in legacy cellular areas. Multi‑GNSS positioning improves fix reliability for real‑time tracking and map accuracy, while ACC detection and optional relay enable ignition awareness and remote immobilizer strategies for anti‑theft workflows.

For integrators and fleet operators focused on telemetry and operational insight, the TK418’s RS232/GPIO expansion and customizable SOS port let you add fuel sensors, door contacts, iButton authentication or Bluetooth peripherals without replacing the core unit. Integration via the EELINK protocol means Plaspy can immediately parse position, event and sensor data for dashboards, alerts and historical reports—helping teams reduce response times, improve routing and protect assets with a compact, reliable device.
