1. Product Title

IFM E1518‑61438 (E61438)‑ Encoder Spring‑Arm Tensioning Accessoryifm

2. Product Overview

E1518‑61438, part number E61438, is a heavy‑duty spring‑arm assembly designed for measuring‑wheel encoder systems. It provides continuously adjustable spring pretension force to keep measuring wheel firmly pressed against moving target surface for reliable speed‑length measurement. Anodized‑aluminum main body paired with stainless‑steel spring component, laser‑engaged scale facilitates convenient pretension setup. Supports bidirectional mounting, allows damping direction switching for upward / downward motion, widely used for web‑speed, length‑measurement applications in printing, textile and metal‑processing production lines.
