DXZ Multi-Functional Travel Limit Switch

Product Overview

The DXZ multi-functional travel limit switch is a high-performance industrial safety control device, specially designed for three-dimensional coordinate control and limit protection of various hoisting and conveying machinery. Combining a high-precision reduction mechanism with a mechanical memory control system, it features high reliability, strong adaptability, and easy installation. It is widely used in heavy machinery and equipment in construction, ports, mining, and other industries.

Product Features

High Versatility

The DXZ limit switch offers a wide range of gear ratios (1:13 ~ 1:960) and supports adjustable limit functions, with an optional potentiometer. It provides mechanical limit protection while outputting displacement digital signals, meeting diverse requirements in different industrial scenarios.

High Precision & Reliability

Certified by type tests for special equipment, the product features high precision: linearity up to 0.1%, cam angle accuracy ≤ 0.005 rad. Its normal service life can reach more than ten years, ensuring long-term stable operation.

Easy Installation

With a rational structural design, the switch is simple to install, allowing users to install, reset, and relocate it independently. Positive feedback from years of use has greatly reduced installation and maintenance costs.

Structure & Working Principle

The DXZ multi-functional travel limit switch consists of a high-precision, high-ratio reducer, a mechanical memory control mechanism, and a sensor. Displacement signals synchronized with the control mechanism are transmitted to the input shaft of the limit switch after speed change via an external idler pulley. The reducer converts them into angular displacement signals at the output shaft, achieving precise position control and limit functions.

Applications

The DXZ multi-functional travel limit switch is widely applied in:

• Construction industry: tower cranes, construction hoists, etc.
• Port machinery: container cranes, portal cranes, etc.
• Mining equipment: mine hoists, conveyors, etc
• Other industrial fields: various conveying machinery requiring spatial coordinate control and limit protection.

Core advantages

The DXZ multi-functional travel limit switch integrates mechanical limit protection and digital signal acquisition. It not only provides reliable safety protection but also enables accurate position monitoring, making it an indispensable safety control device in modern industrial equipment.

Choosing the DXZ limit switch means choosing reliable safety protection for your equipment!
