The 504D Stinger Double Guard Shock Sensor adds dependable impact protection to a vehicle security system using electromagnetic technology (no mechanical parts). It features two-stage detection, providing Warn Away for light impacts and a full alarm trigger for heavier impacts, plus easy integration with a standard plug-in harness.

Electromagnetic Impact Detection

The 504D uses an electromagnetic shock sensor design with no mechanical parts, helping provide dependable impact detection.

Two-Stage Protection

The sensor responds differently based on impact level, offering Warn Away alerts for lighter impacts and a full alarm trigger for heavier hits.

Low Current Draw

With a low-current design, the 504D adds impact protection without placing unnecessary demand on the system.

Easy System Integration

A plug-in harness makes the 504D simple to add to compatible systems with a standard 4-pin sensor input.
