제품 특징
The explosion-proof button is a composite explosion-proof structure (combined with explosion-proof and increased safety types), with a flat rectangular structure. The shell is composed of three parts: an explosion-proof shell formed by integrated injection molding of reinforced flame-retardant nylon PA66 and polycarbonate PC (without traditional bonding surfaces), a stainless steel explosion-proof button rod, 안전성 향상 type wiring terminals on both sides, and a matching installation bracket (also used for electrical protection). The internal button device is divided into two types: normally open and normally closed. The contact element is located in the explosion-proof chamber of the shell, and the opening and closing of the button contacts are controlled by the control lever.
외부 브래킷의 방향을 변경할 수 있으며 상부 및 하부 구조로 각각 조립할 수 있습니다. 상부 구조는 향상된 안전 작동 헤드와 함께 설치할 수 있으며, 하부 구조는 하우징 내부에 설치하는 C35 가이드 레일에 의존합니다.
The metal parts of the explosion-proof button are made of stainless steel material, combined with a plastic shell, which can meet the requirements of strong corrosion resistance.
