Component Specifications

Definition
A specialized printed circuit board (PCB) designed to route electrical signals between a robotic arm controller and end effector devices without signal processing or amplification. It serves as a passive electrical interface that maintains signal integrity while providing physical mounting and connection points for sensors, actuators, and communication lines in industrial automation systems.
Working Principle
The board operates on passive electrical conduction principles, using copper traces on an insulating substrate to create continuous electrical pathways. It maintains impedance matching through controlled trace geometry and utilizes multi-layer construction for signal isolation. The interface follows standard industrial communication protocols (typically digital I/O, analog signals, or fieldbus connections) without active components that could introduce latency or signal degradation.
Materials
FR-4 glass epoxy substrate (UL94 V-0 rated), 1 oz copper traces (35μm), immersion gold surface finish (ENIG), halogen-free solder mask, industrial-grade connectors (Molex, Harting, or Phoenix Contact compatible)
Technical Parameters
  • IP Rating IP67 when installed
  • Signal Types Digital I/O, 0-10V analog, 4-20mA
  • Connector Type M12/M8 circular, terminal blocks
  • Current Rating 2A per channel
  • Signal Integrity <3% attenuation at 10MHz
  • Operating Voltage 5-48V DC
  • Temperature Range -20°C to +85°C
  • Dielectric Strength 1500V AC
Standards
ISO 9409-1, ISO 13849-1, IEC 61131-2, DIN EN 60529
