The **WRPPB-NJAN-R** is a specific part number typically associated with the **W-Series** of wireless push buttons produced by **Steute**. These devices are designed for industrial automation where wiring is difficult or costly. --- ## 1. Component Identification This device is a **Wireless Push Button** that utilizes energy-harvesting technology or battery power (depending on the specific sub-series) to transmit radio signals to a receiver. | Feature | Specification | | :--- | :--- | | **Manufacturer** | Steute Technologies | | **Function** | Wireless Command Device (Push Button) | | **Enclosure Material** | Glass-fibre reinforced thermoplastic | | **Mechanical Life** | > 1 million operations | | **Protection Class** | IP65 or IP67 (dust and water-tight) | --- ## 2. Electronic Operating Principles The electronic core of the WRPPB-NJAN-R revolves around low-power radio transmission. ### A. Radio Technology The "R" in the suffix often denotes the specific radio protocol or frequency (typically **sWave®** technology). * **Frequency:** Usually operates on 868 MHz (Europe) or 915 MHz (USA/Canada). * **Transmission Range:** * Indoors: Up to 40 meters. * Outdoors: Up to 450 meters. ### B. Power Supply These units generally utilize one of two electronic power methods: 1. **Electrodynamic Energy Harvesting:** The mechanical force of pressing the button is converted into enough electrical energy to send a radio telegram (no battery required). 2. **Lithium Battery:** High-capacity cells for applications requiring longer status signals or frequent polling. ### C. Signal Telegram When the button is pressed, the internal electronics generate a 32-bit unique ID. This ensures that: * No interference occurs between adjacent buttons. * The receiver recognizes exactly which button was triggered. --- ## 3. Wiring and Integration Since the device is wireless, the "electronic parts" on the user-side involve the **Receiver Unit**. ```yaml Integration_Steps: 1. Pair the WRPPB-NJAN-R ID with a compatible Steute Receiver (e.g., RF Rx SW). 2. Configure output (Relay, PNP, or Fieldbus like PROFINET). 3. Set operation mode (Momentary, Latching, or Toggle). ``` --- ## 4. Part Number Breakdown (Typical) * **WR:** Wireless Radio series. * **PPB:** Plastic Push Button. * **NJAN:** Specific actuator type (Non-illuminated, flush). * **R:** Radio protocol / Frequency indicator.
