TopFly - TLW2-12B

The TLW2-12B is a hardwired trailer GPS tracker built for rugged, long-dwell trailer and asset tracking and is Plaspy compatible out of the box. With BLE 5.0 support, a large internal rechargeable battery and multi-band cellular connectivity, the TLW2-12B brings reliable real-time tracking and rich telemetry to fleet management, cold-chain monitoring, and anti-theft workflows that must continue whether the trailer is wired to a truck or standing alone in a yard.

Designed for integration with Plaspy, the TLW2-12B delivers frequent location updates (as often as every 3 seconds), buffered reporting when coverage is lost (up to 60,000 points), and remote output control for alarms and accessory relays. Its IP67-rated enclosure, Qualcomm Gen 8C GNSS, and long battery endurance make it a practical choice when you need persistent, secure tracking and sensor data fed into Plaspy dashboards and alerts.

Key Highlights

• Plaspy compatible GPS tracker for trailer and asset tracking, with native support for frequent real-time tracking and buffered storage.
• Large internal rechargeable Li‑ion battery (9600 mAh / 3.6V) that powers long standby and operational intervals when external power is disconnected.
• BLE 5.0 support for Bluetooth sensors (temperature, humidity) and wireless relays to extend cold-chain and accessory telemetry.
• Rugged IP67 waterproof housing (tested to 5 m for 15 hours) and a compact form factor for magnet or screw mounting on trailers and assets.
• Multi-band cellular (FDD, TDD, EGPRS) with Cat M1 support plus TCP/UDP/MQTT/SMS protocols for reliable data delivery to Plaspy services.
• Configurable digital/analog inputs and outputs to connect relays, sensors or ignition/aux inputs and enable remote output control and alarms.
• High-accuracy GNSS (GPS+GLONASS+Galileo+Beidou) with <2 m CEP and fast TTFF for precise location reporting.

How It Works with Plaspy

When paired with Plaspy, the TLW2-12B provides continuous position, motion and telemetry streams that feed Plaspy’s real-time tracking maps, alerts and historical reports. The device uses cellular data (or SMS) to transmit GPS and sensor data, while buffered points are sent automatically once coverage returns, ensuring no gaps in trip history or incident timelines. BLE sensor readings are collected locally and forwarded to Plaspy for cold-chain monitoring and environmental alarms.

• Real-time tracking updates (configurable down to 3-second intervals) for live fleet visibility in Plaspy.
• Buffered location storage (up to 60,000 points) to preserve trip data during coverage gaps and bulk-upload on reconnection.
• Movement, disconnection and external power-loss alerts to trigger Plaspy notifications and escalation rules.
• Configurable inputs that can monitor ignition, door/alarm switches or other auxiliary sensors and report status to Plaspy.
• BLE 5.0 sensor support for temperature & humidity telemetry; wireless relays can be controlled remotely through Plaspy via device outputs.

Technical Overview

Use Cases

• Fleet management: persistent trailer location and movement telemetry for route tracking, utilization analysis and rapid recovery.
• Fleet anti-theft and immobilization workflows: movement and disconnection alerts plus remote-controlled outputs to trigger relays or immobilizer integration via connected hardware.
• Cold-chain monitoring: BLE temperature & humidity sensors paired to the TLW2-12B feed Plaspy with environmental telemetry and threshold alerts.
• Remote yard and off-grid assets: large internal battery and high-capacity buffering ensure historical tracking even when trailers are stored without external power.
• Sensor-driven maintenance and status monitoring: analog/digital inputs let you report door status, alarm events or auxiliary sensors into Plaspy for automated workflows.

Why Choose This Tracker with Plaspy

The TLW2-12B offers a balanced combination of endurance, durability and connectivity that aligns with Plaspy’s real-time tracking and fleet management capabilities. Its 9600 mAh battery and extensive buffering reduce data loss during long yard dwell times, while BLE 5.0 and configurable I/O let fleets extend telemetry to temperature sensors, relays and other Bluetooth sensors. Multi-band cellular and MQTT/TCP support simplify integration with Plaspy’s platform for scalable deployments.

For fleets and asset managers that prioritize reliable position accuracy, long battery life and the ability to keep trailers connected to Plaspy whether they’re wired to a truck or parked for months, the TLW2-12B is a practical, rugged option. It supports remote output control and alarm workflows, FOTA updates for ongoing device management, and the sensor integrations needed for anti-theft, telemetry and cold-chain monitoring through Plaspy.
