Liaohe Mining Co., Ltd. is one of our new customers. Through telephone consultation, they want to purchase a sensor for use in the mine. There is an explosive mixture of methane and coal dust underground in coal mines. In order to ensure the safety of workers, the quality and performance of the sensors must be guaranteed.
Through on-site inspection and communication with technical staff, one of our explosion-proof proximity switches was recommended. Because the contacts of this product are sealed and isolated from the outside world, it is dustproof, moisture-proof, and explosion-proof; the contact surface is plated with gold, silver, rhodium and other metals, so the contact is good, reliable, and has the characteristics of long service life. After purchasing some for trial use, I was quite satisfied with the results, and subsequently added a batch of orders for replacement at the entire site.
Through this cooperation, both parties have deepened their understanding and are very satisfied with the after-sales service provided by our company. He specifically designated our company as a specific supplier for his factory, and also had certain purchasing intentions for other types of sensor products produced by our company, such as photoelectric switches, pull-rope switches, etc.
