FCST FCST-PUEM3 101.4kHz 0.7-1m Near Surface Marker

$12.60

FCST 101.4kHz Near-Surface Markers (EX.ID version) deliver precise underground telecom cable detection up to 1 meter. Built with corrosion-resistant HDPE, these IP68 markers withstand 5 KN pressure and 1.5m drop tests. Enjoy 50 years of maintenance-free service, fully compatible with ED8000 and 3M Dynatel locators.

 

Industry-Specific Frequency: Pre-tuned to 101.4kHz exclusively for telecommunication and FTTx utility networks.  

Rugged Protection & Durability: Certified IP68 waterproof and dustproof. Built to withstand a 1.5-meter (5 in) concrete drop test and up to 5 KN of stress resistance without cracks, leaks, or electronic failure.  

Deep Identification Range: Supports reliable detection at a maximum burial depth of 0.7 to 1 meter.  

Universal Detector Compatibility: Fully readable by industry-standard locators, including the ED8000 and the 3M Dynatel series.  

Extreme Weather Tolerance: Operates smoothly in temperatures ranging from -20°C to 50°C (-4 to 122°F).

Our near-surface electronic markers are perfect for shallow-burial applications, easily placed into narrow drill holes during construction.

Direct Ground Burial: Can be installed vertically just 5cm below the surface for direct tracking of underground conduits.Manhole/Valve Access Points: Ideally suited for placement near subsurface

structures (e.g., telecom manholes or underground valves), maintaining a 2.5cm safety clearance from adjacent utility walls for optimal signal readouts.
