RS-232 is a standard for serial communication transmission of data, widely used in industrial automation, telecommunications, and computer peripherals. This category includes a variety of RS-232 compatible devices such as serial cables, adapters, converters (e.g., RS-232 to USB, RS-232 to TTL), and interface modules. These products enable reliable data transfer between equipment like PLCs, CNC machines, barcode scanners, and legacy systems. Key features often include robust shielding, DB9 or DB25 connectors, and support for baud rates up to 115.2 kbps. Essential for maintaining compatibility in industrial settings, RS-232 solutions help integrate modern devices with older serial-based technologies.
