The SICK OLS20-BB1114142 is a compact and versatile laser distance sensor designed for precise, non-contact measurement applications in industrial environments. It belongs to the OLS20 series from SICK, known for its high accuracy, reliability, and durability. This sensor is ideal for applications requiring precise distance measurement, position monitoring, and process control in various automation and material handling systems.

The ABB GSH204A-C20/0.03 is a 4-pole, 20A, Type A, C-curve Residual Current Circuit Breaker with Overcurrent Protection (RCBO). This advanced protective device is designed for three-phase four-wire circuits that supply modern electronic and electrical equipment. It integrates complete protection against overloads, short-circuits, and earth leakage currents (30mA) into a single compact unit. The key feature is its Type A residual current detection, which is sensitive to both sinusoidal AC residual currents and pulsating DC residual currents. This makes it essential for protecting circuits that feed loads containing rectifiers, switch-mode power supplies, or variable frequency drives (VFDs), where standard Type AC protection may fail.

SIEMENS 6DS1701-8AAA analog input module is suitable for industrial automation control system, which can efficiently collect and process analog signals, and is widely used in manufacturing, energy, transportation and other fields.
