Infrared collision sensors serve as AGVs’ “invisible shields,” enabling non-contact obstacle detection to ensure human-machine safety and operational stability. Their selection directly impacts AGV reliability in complex environments. This guide explores infrared sensor technologies and scenario-based selection strategies.

Core Functions: AGV’s First Safety Line

Precision Detection & Real-Time Response

Detection range: 0.1–5m (diffuse) or 5–30m (through-beam).

±2mm accuracy; ≤0.5ms response time for AGVs ≥1m/s.

94% faster than ultrasonic sensors in narrow aisles.

Environmental Resilience

EMI-resistant design for motor/VFD-dense areas.

IP65/IP67 rating; -30°C to 70°C operation.

Sensor Types: Active vs. Passive

1.Active Infrared: Industrial Workhorse

FM/PWM modulation; >100,000 Lux light immunity.

Multi-output (digital/analog/bus); configurable zones (e.g., 5m warn/3m stop).

Best for: AGV collision avoidance, forklift aisle monitoring.

2.Passive Infrared (PIR): Lightweight Sentinel

Detects human body heat; <1mW power draw.

110° detection angle; 1/3–1/5 cost of active sensors.

Limitations: Ignores static objects; ≤15m range; high false alarms in heat.

Best for: Indoor AGV personnel alerts, low-power robots.

Precision Selection Guide

1.Performance Parameters

Range:

Fixed-route AGVs → 0.1–3m diffuse sensors.

Dynamic AMRs → 5–30m through-beam.

Output: Relay (simple) vs. Analog/CAN (PLC integration).

2.Environmental Adaptation

3.Smart Features

Programmable delay (0–15s) to ignore hanging curtains.

LED/buzzer fault alerts for lens contamination.

4.Cost Optimization

Entry-level (simple avoidance): $70–$140

Advanced (bus communication): $280–$700

TCO Tip: Choose ≥2-year warranty to cover emitter replacements.

Scenario-Based Solutions

Critical Avoidances:

Prevent blind spots with glass/mirrors: Use multi-angle mounting or ultrasonic fusion.

Verify low-reflectivity (10%) performance: Demand third-party test reports.
