Description and Introduction

Optocouplers The **ILD615-4** is a **photoelectric sensor** manufactured by **ifm electronic**. Below are its specifications, descriptions, and features based on the available knowledge base:  

### **Manufacturer Specifications:**  
- **Type:** Photoelectric sensor (retro-reflective)  
- **Operating Principle:** Retro-reflective with polarization filter  
- **Light Source:** Red light (LED)  
- **Sensing Range:** Up to **4 meters** (13.1 ft)  
- **Output Type:** PNP (NO/NC configurable)  
- **Supply Voltage:** **10–30 V DC**  
- **Current Consumption:** ≤ **30 mA**  
- **Switching Frequency:** **500 Hz**  
- **Protection Class:** **IP67** (dustproof and waterproof)  
- **Housing Material:** Plastic (PBT)  
- **Connection Type:** M12 plug connector (4-pin)  
- **Ambient Temperature Range:** **-25°C to +55°C** (-13°F to +131°F)  

### **Descriptions:**  
- Designed for reliable object detection in industrial environments.  
- Uses polarized retro-reflective technology to reduce false triggers from shiny surfaces.  
- Features a visible red light spot for easy alignment.  
- Compact and rugged housing suitable for harsh conditions.  

### **Features:**  
- **Adjustable sensitivity** for fine-tuning detection.  
- **Short-circuit and reverse polarity protection** for enhanced durability.  
- **High switching frequency** (500 Hz) for fast-moving objects.  
- **LED status indicators** (power and switching state).  
- **M12 quick-connect plug** for easy installation.  

For exact technical details, always refer to the official **ILD615-4 datasheet** from **ifm electronic**.
