如何正确选择欧姆龙开关呢?要点是什么?欧姆龙开关种类,型号齐全,在作出最终选择前,必须考虑额定值和所有规格,但要点是开关尺寸、接点最大工作电流、操作力、调节器类型和保护度。


1、首先,选择可安装在所需设备上的开关尺寸。可以从Z尺寸通用微动开关、V尺寸小型微动开关、S尺寸微型微动开关、J尺寸超微型微动开关、专用微动开关中选择。Z尺寸通用微动开关可用作磁熔断式X型号直流开关、控制两个独立电路的DZ型号DPDT微动开关、和用于最高400°C操作的TZ型号高温微动开关。V尺寸小型微动开关可用于采用旋转动作操作的D2MC型号低转矩微动开关。专用微动开关专门针对特殊应用而设计,所以仅限于特定用途,例如门电源开关。


2、接着,根据需要开闭的负载选择接点的最大工作电流。可为大容量负载选择最大值为3 A到21 A的型号,为中等容量负载选择最大值为1 A的型号,为微负载选择最大值为0.1 A的型号。由于接点具有适当电流范围,必须进行这一选择。接点的最大工作电流与开关尺寸严格成正比,所以有时选择尺寸可以自动决定最大工作电流。

 操作力和调节器类型应根据操作微动开关调节器的机器或装置的装置和结构来选择。各型号可选择两个或更多操作力。某些调节器是微动开关的集成部分,其他装置,例如Z尺寸通用微动开关和V尺寸小型微动开关,是单独购买的。应注意,操作力与开关尺寸严格成正比,所以有时选择尺寸可以自动决定操作力。另外,大尺寸开关具有更多调节器类型。


3、通过考虑使用微动开关的环境选择保护度。大多数型号的保护度为IP00,但也有用于V尺寸小型微动开关、S尺寸微型微动开关、J尺寸超微型微动开关的IP67密封型号。Z型号防滴保护度等效于IP62。

How to choose the right omron switch? What's the point? Omron switches are available in a wide range of models. Ratings and all specifications must be considered before a final selection is made, but the key points are switch size, maximum operating current at contact, operating force, regulator type and protection.

1. First, select the switch size that can be installed on the required equipment. You can choose from Z size general micro switch, V size small micro switch, S size micro micro switch, J size super micro micro switch, special micro switch. Z size general micro switch can be used as a magnetic fusing type X dc switch, DZ type DPDT micro switch which controls two independent circuits, and TZ type high temperature micro switch for operation up to 400°C. V size mini micro switch can be used for D2MC model low torque micro switch with rotary operation. Dedicated micro switches are designed for specific applications and are therefore limited to specific USES, such as door power switches.

2, then, according to the need to open and close the load to select the maximum operating current of the contact. Models with A maximum value of 3a to 21a can be selected for large-capacity load, models with A maximum value of 1a for medium-capacity load, and models with A maximum value of 0.1a for micro-load. This choice is necessary because the contacts have an appropriate current range. The maximum operating current of the contacts is strictly proportional to the switch size, so sometimes choosing the size can automatically determine the maximum operating current.

The operating force and type of regulator should be selected according to the device and structure of the machine or device operating the microswitch regulator. Two or more operating forces can be selected for each model. Some regulators are integral parts of the microswitch, while others, such as the z-size universal microswitch and the v-size mini-microswitch, are purchased separately. It should be noted that the operating force is strictly proportional to the size of the switch, so sometimes choosing the size can automatically determine the operating force. In addition, large size switches have more regulator types.

3, by considering the use of micro switch environmental protection selection. The protection of most models is IP00, but there are also IP67 sealed models for V size micro micro switch, S size micro micro switch, J size super micro micro micro switch. The droplet protection of model Z is equivalent to IP62.

How to choose the right omron switch? What's the point? When the actual model number is available, please confirm the ratings and other specifications so that a final decision can be made.
