Description
Product Introduction
The ZL-K Tear Switch is a reliable safety device engineered to detect conveyor belt damage, such as tears, rips, or material intrusions. It operates using a pair of tensioned wire ropes installed along the belt edges. When belt damage causes sagging or displacement, the rope contacts the switch’s trigger mechanism, activating an immediate alarm or shutdown signal.
Built with a durable aluminum alloy body and corrosion-resistant components, the ZL-K ensures longevity in harsh environments. Its compact design and easy installation make it suitable for mining, logistics, and industrial applications. By preventing costly breakdowns and enhancing operational safety, the ZL-K is an essential solution for conveyor system protection.
Functions
-
The ZL-K Tear Switch detects conveyor belt damage through a mechanical sensing mechanism. When a tear, puncture, or structural failure occurs, the displaced or sagging belt causes the installed wire rope to activate the switch, triggering an immediate alarm or shutdown signal to prevent escalating damage.
-
Equipped with brass contacts featuring silver-plated tips, the switch ensures stable electrical conductivity and minimal signal loss. This design guarantees long-term reliability, even under repetitive mechanical stress, with an electrical lifespan exceeding 100,000 cycles.
-
Constructed with an aluminum die-cast enclosure and IP65-rated sealing, the ZL-K resists dust, water ingress, and corrosion. This makes it suitable for harsh industrial environments, including mines, ports, and chemical plants, where exposure to moisture and debris is common.
-
The switch allows customizable tension settings for the sensing wire rope, enabling operators to fine-tune responsiveness based on belt type, load capacity, and operational speed. This adaptability ensures accurate detection without false alarms.
-
Designed for flexible deployment, the ZL-K supports multi-unit installations along a single conveyor belt. Its compact structure and standardized mounting brackets (sold separately) simplify integration into existing systems, accommodating varying belt lengths and layouts.
-
Upon activation, the switch instantly transmits a signal to the control system, halting conveyor operation to prevent material spillage, equipment damage, or worker injury. Its compatibility with PLCs and safety controllers ensures seamless integration into automated safety protocols.
