The Siemens 3RG6142-3MM00 belongs to the SIMATIC series as an ultrasonic proximity switch. It is adept at detecting targets within a range of 60 mm to 300 mm, making it versatile in various applications. The switch's output is classified as normally open with an NPN configuration, facilitating integration into different control systems.

Operating at a rated voltage of 24 V DC, this proximity switch requires a supply current of no more than 30 mA. The rated ultrasonic frequency is set at 300 kHz, ensuring effective object detection with minimal interference. For accuracy, the device is rated at ≤ 1% of the maximum sensing distance, enabling reliable measurement outcomes.

Furthermore, the output voltage drop is limited to ≤ 1 V when the output current reaches 10 mA, which is beneficial for maintaining signal integrity across connected systems. Built-in protections for reverse voltage and inductive overvoltage prevent potential damage, thereby enhancing the longevity of the switch. The unit is also encapsulated within an IP65-rated enclosure, ensuring robust protection against dust and moisture, which is essential for its operation in diverse environments.
