DUK错位开关LHPw-EX..-L50系列介绍
传送带错位（偏离轨道）开关在带式输送机的左侧和右侧成对使用，以减少因传送带错位而造成损坏或破坏的危险。
DUK错位开关的设计考虑了重型服务。 优质的工程结构和最抗冲击的外壳可承受最恶劣的条件。 至少IP67的工业密封圈和超硬实心橡胶垫圈是可靠保护的保证。
• 多达 4 个经 ATEX 认证的触点
• EEx d II C T6
• 速动触点
• 玻璃纤维增强聚酯外壳或铸铁外壳
• 防护等级 67
Conveyor belt misalignment (off-track) switches are used pairwise, left and right of belt conveyors to reduce the danger of damage or destruction by misalignment of the belt.
The design of DUK-misalignment switches considerates heavy duty service. The quality engineered construction and the most impact resistant housings withstand most unhospitable conditions. Industrial sealing rings and an extra hard solid rubber gasket are guarantors for the reliable protection of at least IP67.
• Up to 4 contacts with ATEX-approval
• EEx d II C T6
• Snap action contacts
• Fibre glass reinforced polyester enclosure or cast iron enclosure
• IP 67
