Komplex® Passive Markers – Smart & Analog for Permanent Identification

Komplex markers permanently tag joints, tees, bends and crossings for fast rediscovery in the field. Choose between analog EMS markers and Smart RFID markers depending on your task and documentation needs.

  • Analog (MiM/Marker 120, Marker 2500/Long) & Smart RFID (SM1500)
  • Ball (MAR 100-3D) and disk types for varied installations
  • Utility-specific frequencies for clear attribution
  • Typical locating depth up to ~1.5 m; deep variants up to ~2.5 m (model dependent)
  • Rugged designs for long-term underground use

Smart vs. analog

Smart markers (RFID, e.g., SM1500): passive with a unique ID—ideal for strategic points and records.
Analog EMS markers (e.g., MiM/Marker 120, Marker 2500/Long): proven, maintenance-free solution for permanent point marking.

Form factors & use

  • Ball markers (MAR 100-3D): self-orienting for a distinct locate response.
  • Disk/low-profile (MiM/Marker 120, Marker 2500/Long): installed horizontally; options for standard and deeper cover.

Selection & installation

  • Match frequency to the utility (water, power, telecom, sewer).
  • Place the marker centered above the feature; observe orientation by form factor.
  • Consider soil/depth; use deep variants for greater cover.

FAQ

When to use Smart vs. analog?
Smart with unique ID for identifiable points/data; analog for robust standard marking.
How deep can they be located?
Typically up to ~1.5 m; deep versions up to ~2.5 m depending on model and conditions.
Which form factor should I pick?
Ball for self-orienting point marking; disk for flat installations and deep variants.
