The **BIS013P** refers to a high-performance **RFID Read/Write Head** manufactured by Balluff. It is part of the BIS M series, which utilizes High Frequency (HF) 13.56 MHz technology. These devices are primarily used in industrial automation for tracking workpieces, tools, and materials. ### Technical Specifications Below are the primary electronic and physical characteristics of the BIS013P: | Feature | Specification | | :--- | :--- | | **Interface** | IO-Link (v1.1) | | **Operating Frequency** | 13.56 MHz (HF) | | **Operating Voltage** | 18...30 V DC | | **Current Consumption** | ≤ 50 mA | | **Housing Material** | Brass, Nickel-free coated / PBT | | **Connection Type** | M12 connector (4-pin, A-coded) | | **Protection Rating** | IP67 | | **Installation** | Non-flush (clearance required) | --- ### Core Components and Functionality #### 1. IO-Link Communication The "P" in the model designation often signifies its communication protocol. The BIS013P uses **IO-Link**, which allows for: * Easy integration into existing PLC environments. * Bidirectional data exchange (reading tag UID and writing process data). * Remote diagnostics and parameterization. #### 2. RFID Antenna Coil Inside the M18 cylindrical housing is a copper induction coil. This coil generates a high-frequency magnetic field that powers the passive RFID tags (Data Carriers) when they enter the read range. #### 3. Signal Processing Electronics The unit contains an internal microprocessor that: * Modulates and demodulates the 13.56 MHz signal. * Ensures data integrity through checksums (CRC). * Manages the "In-Zone" signal, indicating if a tag is present. #### 4. Status Indicators (LEDs) The device typically features internal LEDs visible through the housing to indicate: * **Power:** Green light. * **Tag Detected:** Yellow/Orange light. * **Error/Diagnostic:** Flashing sequences or Red light. --- ### Installation Considerations * **Metal-Free Zone:** Since it is a non-flush mount sensor, there must be a specific distance between the sensing head and any surrounding metal to prevent interference with the magnetic field. * **Cable Length:** When using IO-Link, the cable length between the BIS013P and the IO-Link Master should not exceed 20 meters.
