The BA-R138-AR Micro Limit Switch is a reliable device with a rated current of 20A and a voltage of 250V. It features gold-plated contacts and can operate seamlessly in temperatures from -55°C to 85°C, ensuring precision in industrial automation, home appliances, and automotive systems.
The BA-R138-AR Micro Limit Switch is designed to meet demanding industrial applications where precision and durability are critical. Rated at 20A 125VAC and 20A 250VAC, it can easily handle high current operations. Gold-plated contacts ensure minimum contact resistance (50mΩ), reducing energy loss and extending service life. The rugged design supports a wide operating temperature range of -55℃ to 85℃, making it ideal for extreme environments and capable of maintaining stable performance under repetitive mechanical stress and fluctuating temperature conditions.
The BA-R138-AR Micro Limit Switch features a precise actuation mechanism. The operating force range is 311.9gf to 482gf (11-17 ounces), and the release force is as low as 283.5gf, ensuring consistent response speed. The differential travel of 0.038-0.063 mm ensures accurate signal transmission. The minimum over-travel specification of 0.254 mm prevents mechanical failure when the actuator moves excessively, making it a reliable choice for applications that require repeatable accuracy, such as conveyor systems, robotic arms, and safety interlocks.
The BA-R138-AR Micro Limit Switch excels in environments where electrical insulation and safety are critical. Withstanding voltages up to 500V between terminals and 1500V between terminals and housing, it meets stringent safety standards. Insulation resistance of 100MΩ at 500VDC ensures reliable isolation and minimizes the risk of short circuits. Gold-plated contacts reduce oxidation and enhance conductivity, ensuring stable performance over millions of cycles.
The BA-R138-AR Micro Limit Switch’s compact size and T85 5E4 housing allow for easy integration into space-constrained designs. The ±0.38 mm operating position tolerance ensures precise alignment with the actuator, reducing installation errors.
The BA-R138-AR Micro Limit Switch is designed for long life, reducing maintenance costs and downtime. The rugged construction is dust-proof, moisture-proof, and shock-proof, extending service life in harsh environments, and can withstand rapid cycles without performance degradation, making it a cost-effective solution for high-load applications.
