Product Description

1. Product Overview

The PLR10D-L60-00 Belt Misalignment Switch is a critical component of conveyor safety systems. It uses a two-stage angle-triggered mechanism to monitor conveyor belt deviation in real time. When the roller deflects to the first-stage angle (10°~20°), it triggers an alarm signal; when reaching the second-stage angle (30°~45°), it immediately cuts off the conveyor power supply, effectively preventing belt tearing, material spillage, and other accidents. Compliant with GB/T 14048.5 standards, the product features IP67 protection and operates in extreme industrial environments from -25°C to 80°C.

3. Installation Guide

Positioning
Install a pair of switches every 30-35 meters along the conveyor, focusing on prone areas such as head, tail, and convex sections. The roller should be perpendicular to the belt edge, with its lower 1/3 aligned with the belt edge and spacing adjusted to 50-100mm.
Mounting
Secure the bracket to the conveyor frame by welding or bolts, ensuring no displacement under 0.75mm amplitude (10g) vibration. Seal the junction box with adhesive to prevent dust ingress.
Wiring

1.Red wire: Live (AC 380V)

2.Blue wire: Neutral

3.Yellow wire: First-stage alarm signal

4.Green wire: Second-stage shutdown signal
4. Operation Instructions

Normal Operation
When the belt is centered, the roller is vertical, and contacts remain normally open.

First-stage Alarm
When the belt deviation pushes the roller to 12°, the yellow contact closes, triggering audible/visual alarms or activating belt alignment devices.
