Reliable Multi-Channel Sensor Interface for Industrial Automation

The Pepperl+Fuchs NDS-F146-8E2-V1 is a robust WIS (Wireless Interface System) module designed to streamline sensor integration in industrial automation. Featuring 8 independent sensor input channels, it supports 3-wire DC PNP sensors (switched high), enabling simultaneous connection of multiple proximity or inductive sensors. With a 12 V DC ±10% supply voltage (overload and short-circuit resistant), it ensures stable power delivery, while a low input current of 1 mA minimizes energy consumption. The module’s compact design and flexible installation allow seamless integration into tight spaces, making it ideal for complex machinery setups. Its fast signal transfer and reliable data processing enhance system efficiency, supporting real-time monitoring and control in applications like conveyor systems, robotic cells, and assembly lines.

Rugged Construction for Demanding Industrial Environments

Engineered to withstand harsh conditions, the NDS-F146-8E2-V1 boasts an IP65 protection rating, guarding against dust and water jets, suitable for wet, dusty, or high-vibration environments. It operates within a 0–50°C ambient temperature range and stores safely at -25–85°C, ensuring resilience in extreme industrial climates. The module’s durable build, combined with a lightweight design (140 g), simplifies mounting in space-constrained machinery. A critical feature is the maximum 5 m cable length between the module and WIS transmitter, maintaining signal integrity and reducing interference for consistent performance. Compliance with industrial standards guarantees reliability in challenging manufacturing or logistics environments.

Efficient and Versatile System Integration

Designed for seamless automation networking, this WIS module offers a MTTFd (Mean Time To Failure) of 465 years and a 20-year mission time, reflecting long-term reliability for non-safety-integrated applications. Its 0% diagnostic coverage suits basic control systems, while support for PNP sensors enhances compatibility with common industrial setups. The module’s 15 kΩ internal resistor and 2.5 W maximum transfer power (1.5 W at 5 mm) ensure stable signal transmission, minimizing errors in high-speed operations. Ideal for retrofitting or new installations, it simplifies wiring and reduces setup time, making it a versatile choice for automotive manufacturing, process control, and material handling systems where efficient sensor management is essential.
