YHJ-1200(A) Intrinsically Safe Laser Pointer for Mining

Product Overview

The YHJ-1200(A) intrinsically safe laser pointer for mining is an instrument that integrates electronics, optics, and precision mechanics. It features an aesthetically pleasing design, compact size, light weight, and explosion-proof characteristics. The instrument can be quickly mounted on anchor bolts via a suspension assembly, allowing for coarse adjustment over a 360° range and fine adjustment with high accuracy; adjustment is convenient, and the braking mechanism is reliable. The product incorporates a self-developed optical system and supports both red and green light sources, with beam spot size and effective range tailored to meet the requirements of underground mining operations. It is powered by the PL205667 3.7 V power pack, eliminating the need for on-site connection to external power supplies, which makes it suitable for widespread use in facilities without AC power or in locations subject to frequent relocation, enabling continuous operation over extended periods. By integrating electronics, optics, and precision mechanics and utilizing the long-lasting, continuously operable PL205667 3.7 V power pack, this instrument is particularly well-suited for work sites where power supply connections are challenging. Coarse adjustment is achieved through a 360° rotatable locking mechanism, while installation is facilitated by a fixing rod and a suspension assembly locking device, making instrument mounting both convenient and rapid. Furthermore, the fine adjustment mechanism allows for lateral and longitudinal adjustments within a range of no less than ±1.5°.
