In the world of industrial automation, heavy machinery, and advanced engineering, the precise measurement of tilt and inclination is not just a convenience—it is a critical component of safety, stability, and operational efficiency. The APOLLO Digi-Rotary KIT, identified by the part number 05-20-40010, represents a sophisticated and self-contained solution designed specifically for this purpose. This device, often described as a longitudinal slope sensor, embodies a fusion of robust mechanical design and modern digital electronics to deliver reliable angular data in demanding environments.
At its core, the kit is a complete Sensor Assembly. This is a significant feature, as it implies that the user receives a fully integrated, ready-to-install system. There is no need to source separate components or manage complex calibrations; the kit is engineered to function as a cohesive unit right out of the box. This plug-and-play philosophy drastically reduces installation time and potential for error, making it an attractive option for both OEMs (Original Equipment Manufacturers) and for maintenance and retrofit projects.
The heart of its functionality lies in its descriptive title: Digi-Rotary and Longitudinal Slope Sensor. "Digi-Rotary" indicates that the sensor measures rotary motion—specifically, the rotation of an internal pendulum or mass relative to the force of gravity—and translates this mechanical movement into a Digital signal. Unlike older analog sensors that output a variable voltage, a digital output is far more resilient to electrical noise, signal degradation over long cables, and electromagnetic interference. This makes the reading exceptionally stable and accurate.
The term Longitudinal Slope Sensor defines its primary measurement axis. This sensor is engineered to detect the angle of tilt along a single, specific plane—the longitudinal axis. Imagine the forward-and-backward tilt of a piece of heavy machinery, the pitch of an aerial work platform, or the inclination of a solar panel array. This is the longitudinal slope. By focusing on this single axis, the sensor is optimized to provide the most accurate and responsive data for applications where this specific orientation is paramount to the system's function.
The physical integration is achieved through a 7-pin Screw Thread design. This serves two crucial purposes. First, the screw thread allows for secure and straightforward mechanical mounting. It can be easily screwed into a corresponding threaded receptacle on a machine frame or structure, ensuring a firm and stable connection that can withstand vibration and shock. Second, the 7-pin connector is the gateway for electrical integration. This multi-pin interface typically carries power to the sensor and transmits the digital output signal, and may also provide for configuration or diagnostic functions, all within a single, robust, and sealed connector to protect against moisture and contaminants.
The output signal is a PWM (Pulse Width Modulation) wave. This is a clever and widely used digital communication method. Instead of sending a numeric value directly, the sensor outputs a square wave where the duration of the "on" pulse (the pulse width) is directly proportional to the measured angle. A microcontroller or PLC (Programmable Logic Controller) can easily measure this pulse width to calculate the exact inclination. PWM signals are simple, efficient, and can be transmitted over long distances without losing their essential information, making them ideal for industrial control systems.
In summary, the APOLLO Digi-Rotary KIT (05-20-40010) is far more than the sum of its parts. It is a thoughtfully engineered system that delivers a critical measurement—longitudinal inclination—with digital precision and robust reliability. From ensuring the safe operation of construction equipment to optimizing the angle of renewable energy systems, this sensor assembly provides a trusted, ready-to-deploy answer to the fundamental question: "What is my angle?"
