Magnetic Tube Circuits (Opti™ Series)

Use surface gauss and pull (¼″/½″ balls) to match circuit to your burden depth and particle size.

How to Use the Magnetic Tube Circuits Table

Tube circuits control field reach (how far the magnet works into your product) and hold (how strongly captured metal stays put). The right circuit is the difference between “some capture” and consistent, audit-ready performance.

What the numbers mean

  • Nominal Gauss = surface intensity → best for very fine ferrous & stainless fines near the tube.
  • Pull (¼″ / ½″) = holding force → resists wash-off at higher flow, vibration, or deeper burden.
  • Profile = intent (High Gauss, High Pull, Balanced, High Temp, HACCP).

Pick a circuit by application

  • Fine powders (flour, sugar, spices, fines): choose High Gauss.
  • Deeper burden / higher rate (pellets, granules): choose High Pull or large-tube.
  • Abrasive media: choose Balanced to protect performance and the tube.
  • Hot processes: choose High-Temperature.
  • Food audits: choose HACCP-rated circuits/tubes.

Tip: Numbers work best with good layout—keep burden depth low, use multiple rows where possible, and match tube spacing to your particle size and flow. If you’re unsure, we’ll size the circuit and drawer arrangement for your material.
