dc425 asbolute multi-turn analog duracoder

AMCI DC425 Absolute Analog Multi-turn Rotary Shaft Encoder

FEATURES:

IP67 rated; superior durability in harsh environments
5/8" stainless steel shaft
Aluminum housing
Ideal for high-shock applications - withstands mechanical shock & vibration

DESCRIPTION

The DC425 DuraCoder is an absolute analog multi-turn rotary shaft encoder, offering an analog current or analog voltage output over single or multiple turns.

Built on DuraCoder's foundation of outstanding durability and value, the DC425 was originally designed for outdoor process control applications. Features like an IP67 rated aluminum housing, 5/8" stainless steel shaft, and resolver-based sensing technology contribute to the DuraCoder's fail-safe reliability, making it the perfect choice for hydroelectric, water treatment, or water purification facilities.

When customers demand reliable absolute analog multi-turn rotary shaft encoder performance in an environment of continuous mechanical shock and vibrations, and exposure to air and liquid-borne contaminants, the choice is easy - DuraCoder.
