WRF433 Queclink Stolen Vehicle Sensor

Core Purpose

WRF433 is a compact sensor built for stolen vehicle recovery. It is designed to work alongside GNSS trackers and add another layer of communication support when vehicle location needs to remain available in difficult conditions.

Connectivity and Communication

The device combines BLE 5.2 with RF433 communication. In normal use, this supports close-range integration with a tracker, while RF433 provides an extra path for location support during emergencies or when another signal path is obstructed. This redundant design helps keep recovery operations more dependable.

Tracking Support

WRF433 does not replace the tracker. Instead, it strengthens the overall recovery setup by working with GNSS tracking devices and helping maintain location support when conditions are harder than usual. That makes it useful in theft scenarios where signal continuity matters.

Power and Environmental Suitability

The sensor supports a 9–32V DC input, which suits common vehicle power environments. Its IP67 rating helps protect it from water and dust, and the 720 mAh backup battery adds support if main power is interrupted. The compact 75 × 39.5 × 20.5 mm body also makes hidden installation easier.

Expansion and I/O Support

The unit includes one ignition or trigger input and one digital output, which gives it basic integration options within a vehicle setup. It also uses an internal BLE antenna and includes RX/TX lines for connection support, keeping the hardware practical without making installation overly complex.
