EC11 surface mount encoder is resistant to high temperatures, equipped with a push-button switch, a 360-degree rotating volume knob, 20 pulses, and 30 bits
EC11 SMD Encoder – High Temperature Resistant with Push Switch, 360° Rotation 20 Pulses 30 Positions
Description
The EC11 SMD Encoder is a compact surface-mount rotary control component engineered for high-density PCB designs, integrating 360° infinite rotation, a built-in tactile push switch, 20-pulse output and 30 precise detent positions. Featuring excellent high-temperature resistance for reflow soldering, this mini rotary knob is an ideal drop-in replacement for traditional through-hole encoders, significantly streamlining automated SMT assembly lines for mass production. As a cost-effective human-machine interaction solution, it delivers consistent performance even in high-heat working environments, making it widely favored by electronics manufacturers across consumer, industrial and smart home sectors.
Specification
- High-Temperature Resistant SMD Structure
The full housing adopts heat-resistant engineering plastic that withstands up to 260°C reflow soldering for 10 seconds, perfectly matching standard SMT assembly processes without manual secondary soldering. This drastically reduces production labor costs and improves overall manufacturing efficiency.
2. 20 Pulses & 30 Precise Detent Positions
Designed with 30 crisp detent positions and corresponding 20-pulse incremental AB phase output, it ensures accurate position feedback during 360° rotation. Each step delivers clear, uniform tactile click, preventing misoperation even with quick adjustments.
3. Integrated Tactile Push Switch
The all-in-one design combines rotary encoding function and a 1.5N-3N actuation force push switch, supporting operations like “rotate to adjust, press to confirm”. It saves PCB space compared to separate encoder + button layouts, creating a more streamlined control experience.
4. Long Service Lifespan & Stable Performance
Adopting silver contact points and wear-resistant metal rotor structure, it supports over 50,000 rotation cycles and 100,000 push operations. The anti-oxidation coating on pins guarantees stable signal output without intermittent issues even after long-term usage.
5. Miniature Low-Profile Form Factor
With a body diameter of only 11mm and optional total height as low as 5mm, this ultra-compact SMD encoder fits perfectly into slim, space-constrained device designs, which is impossible for bulkier through-hole alternatives.
6. Wide Operating Temperature Range
It maintains reliable working performance across -30°C to +85°C, far exceeding the temperature tolerance of ordinary consumer-grade encoders. It can adapt to harsh working conditions that involve continuous heat generation inside devices.
