The **FRTS-5E-R** is an electronic component primarily classified as a **Rotary Torque Sensor** (specifically a non-contact, flange-to-flange type). These sensors are engineered for high-precision measurement of torque in rotating shafts or stationary systems. --- ### 1. Key Technical Specifications Below are the typical electronic and mechanical characteristics associated with the FRTS-5E-R series: | Parameter | Description | | :--- | :--- | | **Rated Capacity** | 5 N·m (Newton-meters) | | **Signal Output** | ±5V or 0-10V DC (Typical for the -R series) | | **Accuracy Class** | 0.1% to 0.2% F.S. (Full Scale) | | **Power Supply** | 24V DC (Standard industrial input) | | **Sensor Type** | Strain Gauge based with Wireless/Rotary Transformer | | **Max Rotation Speed** | Up to 8,000 - 10,000 RPM (depending on configuration) | --- ### 2. Internal Electronic Architecture The FRTS-5E-R utilizes a sophisticated internal design to transmit data from a moving part to a stationary controller: * **Strain Gauge Bridge:** The core sensing element. It detects the physical deformation of the metal shaft and converts it into a change in electrical resistance. * **Rotary Transformer/Inductive Coupling:** To avoid the wear and tear of physical "brushes," this sensor uses electromagnetic induction to pass power into the rotating shaft and send the torque signal back out. * **Internal Signal Conditioner:** An integrated circuit (IC) that amplifies the micro-volt signals from the strain gauges into a robust, noise-resistant voltage signal. * **Temperature Compensation:** Built-in resistors that stabilize the output signal even if the motor or environment heats up during operation. --- ### 3. Wiring and Connection The device usually features a multi-pin circular connector (often M12 or GX series). The standard pinout logic is as follows: ```yaml Pin 1: V+ (Excitation/Power Input +24V) Pin 2: V- (GND/Power Ground) Pin 3: Sig+ (Torque Signal Output +) Pin 4: Sig- (Torque Signal Output - / Reference) Pin 5: Shield (Earth/Ground for Noise Reduction) ``` --- ### 4. Common Applications * **Motor Testing:** Measuring the efficiency and peak torque of electric motors. * **Automotive R&D:** Testing drivetrain components and steering systems. * **Bolt Tightening:** Precision monitoring in automated assembly lines. * **Calibration:** Serving as a reference standard for torque wrenches. ---
