Encorder

Precision Encorder Resistor – Ultra‑Stable, Code‑Controlled Voltage Division

The Encorder is a high‑precision, adjustable passive resistor engineered for instrumentation and precision analog applications. It combines a low‑temperature‑coefficient metal‑film resistive element with an integrated rotary encoder head, allowing zero‑drift, repeatable resistance settings via a simple key‑turn mechanism or optional digital interface. The design features a four‑terminal, isothermal layout for minimal self‑heating, and the encapsulant is resistant to humidity and vibration, ensuring reliable performance in harsh environments.

Key design highlights include an R‑value range of 1 kΩ to 10 MΩ, 0.1 % tolerance, a 200 V DC rating, and a 0.1 W power dissipation specification. The temperature coefficient is ±0.5 ppm/°C, guaranteeing stability over a ±70 °C to +250 °C operating band. The Encorder’s thin‑film technology ensures a voltage coefficient below 0.01 %/kV and a noise figure under 5 nV/√Hz, making it ideal for precision ADC reference networks and high‑accuracy sensor interfaces.
