The Novotechnik LWH 400 is a rod-style conductive plastic linear potentiometer position sensor with 400mm measurement stroke. It delivers ratiometric (voltage divider) output with ±0.04% linearity, resolution better than 0.01mm, and repeatability of ~0.002mm. The anodized aluminum housing with decoupled brush contacts ensures long operational life (up to 100 million movements) at speeds up to 10 m/s. The DIN 43650 standard connector and four-sided mounting grooves simplify installation. Operating from -30°C to +100°C with IP55 protection, it is suited for injection molding machines, hydraulic/pneumatic cylinder position feedback, machine tools, printing equipment, woodworking machinery, and measurement systems requiring precise linear displacement measurement.
**Q: How is the LWH 400 installed?**
A: The sensor body features four-sided mounting grooves for flexible orientation. Snap-in mounting and optional side clamps allow tool-free installation. The conductive plastic track should face downward to prevent debris accumulation.
**Q: What is the expected service life?**
A: Up to 100 million movements under normal operating conditions, with some reports of up to 1 billion cycles depending on speed, load, and environment.
