Encoder vs Potentiometer: How to choose

6月 4, 2025

When you need to measure position or movement in automation, robotics, or industrial control, two names usually come up: encoder vs potentiometer. While both serve a similar purpose—providing position feedback—their working principles, strengths, and ideal use cases are very different. Let’s dig deeper into how these two popular sensors stack up so you can make a confident choice for your next project. What Is an Encoder? An encoder is a sensor that converts mechanical movement—whether rotation or linear travel—into digital signals. It uses optical, magnetic, or capacitive technology to detect movement and outputs either pulses (incremental) or unique codes (absolute). Encoders stand out for their high precision, reliability, and seamless […]

Encoder Symbol: Your Guide to Understanding and Using Encoder Symbols in Engineering

When you’re working with automation, robotics, or industrial control systems, you’ll often come across the term “encoder.” But have you ever stopped to wonder what the encoder symbols means in technical diagrams? Let’s break it down together—so the next time you see an encoder symbol, you’ll know exactly what you’re looking at and why it matters. What Is an Encoder Symbol? An encoder symbol is a standardized graphic used in electrical and automation schematics to represent an encoder component. Just like a musical note tells a musician what to play, the encoder symbol tells engineers and technicians what’s happening in the circuit. It’s a visual shorthand that helps everyone speak […]

Encoder Guide: Principles, Types, and Industrial Applications

6月 4, 2025

If you’ve ever marveled at how a robot arm knows exactly where to stop, or wondered how a conveyor belt keeps things moving at just the right speed, you’ve already seen encoders at work—though you might not have realized it. Encoders are like the nervous system of modern machines. They sense movement and position, then turn that information into signals your control system can actually use. Let’s dive in and see what makes encoders tick, why they matter, and how you can pick the right one for your job. What’s an Encoder, Anyway? Think of an encoder as a translator. It takes the physical movement—rotation or straight-line travel—and converts it […]
