The **W2CE-13C-R2/N** is a specific part number typically associated with high-precision industrial components, most commonly found in the catalog of **Omron** or similar industrial automation manufacturers. It generally refers to a specialized **Electronic Counter** or **Digital Tachometer** module. Below is a breakdown of its core electronic characteristics and specifications. --- ### 1. Technical Specifications The following table outlines the general electronic parameters for this class of device: | Feature | Specification | | :--- | :--- | | **Component Type** | Digital Electronic Counter / Timer | | **Input Type** | NPN / PNP (Selectable) | | **Voltage Supply** | 100 to 240 VAC (Standard) | | **Display Type** | 7-Segment LED (Red/Green) | | **Max. Counting Speed** | 30 Hz to 5 kHz / 10 kHz (Configurable) | | **Output Type** | Relay Contact (SPDT) or Transistor Output | | **Degree of Protection** | IP66 (Front panel) | --- ### 2. Key Electronic Functions This component serves several critical roles in an automated circuit: * **Pulse Processing:** The device receives electronic pulses from sensors (like inductive proximity switches or rotary encoders) and translates them into a human-readable numeric value. * **Signal Filtering:** It includes internal circuitry to filter out mechanical contact bounce or electronic noise that could cause "ghost" counts. * **Memory Retention:** It typically features an internal **EEPROM** to retain count values even when the power supply is disconnected. * **Logic Control:** The "R2" suffix often denotes a dual-relay output configuration, allowing the device to trigger external machinery once a specific count threshold is reached. --- ### 3. Connection Diagram (General Layout) Industrial electronic parts of this type follow a standard terminal block layout: ```text Terminal Function ---------------------------- 1 - 2 Power Supply (L/N) 3 - 4 Relay Output 1 (N.O./N.C.) 5 - 6 Relay Output 2 7 Common (0V) 8 Input A (Pulse) 9 Input B (Reset/Gate) 10 12VDC Sensor Power Out ``` --- ### 4. Application Use Cases * **Production Lines:** Counting items passing on a conveyor belt. * **Length Measurement:** Working with an encoder to measure the length of cable or fabric. * **RPM Monitoring:** Acting as a tachometer to monitor the speed of a motor. * **Batching:** Stopping a pump or motor once a specific volume or count is achieved.
