Industrial-grade large-sized electrical terminals provide stable and reliable contact. Designed to reduce signal surges and resist electromagnetic interference (EMI) to protect data integrity. The RS485 anti-interference device connects in series on the signal line. Passive RS485/RS422 broadband isolator operates reliably in high-interference environments, ensuring stable control data communication. Applications include industrial monitoring, PTZ camera systems, and industrial equipment control. Features: - Operating temperature range: -45°C to +85°C - No optical isolation—eliminates temperature drift and power supply noise - No external power supply required; passive design replaces power-stealing methods - Prevents secondary interference commonly associated with powered RS485 opto-isolators - Fast transient response: 12 ns - Standard RS485/RS422 impedance matching; return loss: 18 dB - Low insertion loss: < 0.8 dB - Housing material: plastic and metal - Color: black and blue Package includes: - 1 × RS485 anti-interference device Note: Color appearance may vary slightly due to lighting and screen settings. Slight dimensional variation (±1–3 cm) may occur due to manual measurement.
