# Industrial Specification: Receiver Unit

## 1. Technical Definition
The detection component of a safety light curtain that receives the optical beam from the transmitter unit.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-20 m**. Failure boundary: **Optical power density below 0.1 μW/cm² at receiver aperture**, Mechanism: **Beam divergence exceeding 0.5 mrad combined with atmospheric attenuation coefficient of 0.2 dB/km at 950 nm wavelength, causing signal-to-noise ratio to fall below 10 dB threshold**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

- **Caution**: 

### Q: What is the primary function of a receiver unit in a safety light curtain system?
**A**: The receiver unit detects the optical beam emitted by the transmitter unit. When the beam is interrupted, it signals the machinery to stop or take safety measures, preventing accidents in industrial environments.

### Q: What materials are used in the construction of this receiver unit and why?
**A**: This receiver unit uses ABS plastic and polycarbonate for impact-resistant housing, and aluminum alloy for structural components. These materials provide durability, corrosion resistance, and protection for internal electronics in harsh industrial settings.

### Q: How does the sensor array in the receiver unit work with safety light curtains?
**A**: The sensor array consists of multiple photoelectric sensors that detect the infrared light beams from the transmitter. When any beam is broken, the control circuit board processes this interruption and triggers an immediate safety response from the connected machinery.
