The Yokogawa AQ6315B is a compact and cost-effective benchtop optical spectrum analyzer (OSA) designed for basic wavelength and power measurements in optical communication systems. It is an improved version of the AQ6315A, offering enhanced performance and usability for manufacturing, installation, and maintenance applications. The analyzer supports single-mode fiber measurements and provides reliable performance for routine testing of optical components.

The ABB MS165‑42 (1SAM451000R1015) is a manual motor starter with built‑in motor protection designed to protect three‑phase and single‑phase motors from overload, short circuit, and phase failure. It combines switching, disconnect and protective functions in one compact unit and is ideal for use in control panels, industrial machinery, and motor circuits.

The ABB S202M‑C6DC is a 2‑pole miniature circuit breaker (MCB) from the ABB System pro M compact S200MDC range, specifically designed for DC electrical protection applications. It provides reliable overload and short‑circuit protection in DC power distribution systems and industrial control circuits. The breaker features a Type C thermal‑magnetic trip characteristic, suitable for circuits with moderate inrush currents, and is engineered for high breaking capacity up to 10 kA at its rated DC voltage. With a compact design for DIN‑rail mounting, clear ON/OFF indication, and robust terminal connections, the S202M‑C6DC is suitable for protective and switching roles in industrial equipment, renewable energy systems, battery‑powered systems, and other DC‑based installations.
