Product Description

The TRD-NH20-RZW encoder is an incremental rotary encoder featuring high-resolution optical sensing within a compact 20mm housing. Designed for precise position feedback, it delivers dual-channel quadrature output (A/B phases) and an index (Z) pulse, supporting direct integration with PLCs, motor drives, or motion controllers. Operating at 5-24V DC, it functions reliably across industrial temperatures (-20°C to +85°C), suitable for automation, robotics, and CNC applications. Withstand up to 6000 RPM and IP50-rated protection, its key strengths include rugged construction, minimal hysteresis, and repeatability. However, alignment sensitivity and potential electromagnetic interference in dense setups require careful installation. No built-in battery or display; resolution variants range from 100 to 2048 PPR for flexible accuracy demands.
