STAHL 8455 Series Potentiometers: Precise Analog Control for Hazardous Areas
When you need reliable and simple analog control in demanding industrial environments, the
Stahl 8455 Series Potentiometers deliver robust performance and certified safety. Designed for panel mounting, these devices provide a straightforward user interface for adjusting nominal values, ensuring precision where it matters most.
Versatility for Any Application
The Stahl 8455 series is engineered for flexibility, offering two primary configurations to suit diverse installation requirements:
Model 8455/2: Comes with a pre-installed 6-meter connection lead, ideal for quick and secure setups.
Model 8455/4: Features connection terminals for custom wiring solutions.
With a wide resistance range from 100 Ω to 1 MΩ and a power rating of 2 W, these potentiometers can be integrated into a vast array of control circuits. The devices are built with a durable polyamide enclosure and feature a carbon film resistor, ensuring long-term stability and a resistance tolerance of ±20%.
Certified for Safety in Hazardous Environments
Safety is paramount in industrial settings, and the 8455 series is fully certified for use in hazardous gas and dust locations. Holding both
ATEX and IECEx certifications, these potentiometers are approved for use in Zones 1, 2, 21, and 22, providing peace of mind and ensuring compliance with global safety standards.
The 8455/2 model (with connection lead) boasts a high degree of protection at
IP66, making it completely dust-tight and protected against powerful water jets.
