M330系列限位开关series limit switch

金属外壳、防护等级IP65、二触头、速动开关

metal cover, protection class IP65, two contact, snap action switch

结构structure

        M330系列开关外壳为压铸轻金属外壳，进行过表面涂漆处理，可防止海水浸蚀，开关的密封件抗油污影响，并在使用中不会受到损坏。所有外露金属部件为不锈钢材料或涂有表面防护层。传动和转动部件材料为耐磨的塑料。

        此系列开关zui重要的特点是机械寿命长，操动件种类丰富。摇臂操动件旋转部位的摩擦力极小，因而机械磨损极小。双向摆动操作角可达90°，且复原力随着角度增加而增加。

       所有摇臂操动件在360°范围内可连续调节，操动头部可作4x90°的位置调节，根据需求，对H、3H及8H形式的操动件，我们还可提供齿状咬合衔接式连接，这时调节只能以10°为单位进行调节。

       此系列开关内的速动开关元件技术性能优异，触头为镍一金材料，保证可靠的电接触。

此系列开关还有耐高温型，温度至+160°。

M3301 series switch: the cover is die-casting light metal; finishing paint, it can prevent the sea from dipping; the sealing part can stop pollution and not be broken duo to operation. All the metal material that betray outside is stainless or painting protection, drive or turn part is belong to endurable plastic material.

The most important character of this kind of switch is mechanical life long, more operate kinds, shake arm action part has small friction, so the mechanical abrasion is very small. Double-shake operate angle can reach up 900 ; the recover force will be increasing with angle.

All the shake operate part can adjust in the range of 3600 ; the operate top head can adjust 4X900 ,we also can offer the joggle connection for H ,3H and 8H type operation according to the requirement. It only can adjust at 100 as unit

This action switch have good technical performance in the switch range, the contact is belong to nickel-golden material, it can prove the reliable electric contact.

These series switch can endurance high temperature +1600
