LEMO unipole and multipole connectors

This catalogue gives the complete description of LEMO unipole and multipole type connectors. The LEMO manufacturing

programme has been extended to almost 40 series divided into 7 product families with specific mating and environmental

characteristics. Each series includes a wide variety of plug, socket, coupler and bridge plug models, available in contact

configurations adapted to all round cables, including up to 114 conductors, and a maximum diameter of 30 mm.

Watertight and vacuumtight models are also available. Since LEMO connectors are perfectly screened and designed to

guarantee very low resistance to shell electrical continuity, they are particularly adapted to applications where electro-

magnetic compatibility (EMC) is important.

Precision modular connectors to suit your application

Over 75000 connectors

Since its creation in Switzerland in 1946 the LEMO Group has been recognized as a global leader of circular Push-Pull

connectors and connector solutions. Today LEMO and its affiliated companies, REDEL and COELVER, are active in

more than 80 countries with the help of over 40 subsidiaries and distributors.

The modular design of the LEMO range provides over 75000 connectors from miniature ø 3 mm to ø 50 mm, capable of

handling cable diameters up to 30 mm and for up to 114 contacts.

LEMO’s Push-Pull Self-Latching Connection System

This vast portfolio enables you to select the ideal connector configuration to suit almost any specific requirement in most

markets, including medical devices, test and measurement instruments, machinery, audio video broadcast, telecommuni-

cations and military.

This self-latching system is renowned worldwide for its easy and quick mating and unmating features. It provides absolute

security against vibration, shock or pull on the cable, and facilitates operation in a very limited space.

The LEMO self-latching system allows the connector

to be mated by simply pushing the plug axially into

the socket.

Once firmly latched, connection cannot be broken by

pulling on the cable or any other component part other

than the outer release sleeve.

When required, the connector is disengaged by a

single axial pull on the outer release sleeve.

This first disengages the latches and then withdraws

the plug from the socket.

LEMO connectors are recognized by the Underwriters Laboratories (UL). The approval of the complete system (LEMO

connector, cable and your equipment) will be easier because LEMO connectors are recognized.

CE marking

means that the appliance or equipment bearing it complies with the protection requirements of one or

several European safety directives. CE marking

applies to complete products or equipment,

but not to electrome-

chanical components, such as connectors.

LEMO connector specifications conforms the requirements of the RoHS directive (2011/65/EU) of the European Parlia-

ment and the latest amendments. This directive specifies the restrictions of the use of hazardous substances in electrical

and electronic equipment marketed in Europe.

Step 1: Select connector series

3 steps to select the right connector

Select the appropriate LEMO connector series according to the environmental parameters that will affect your device

or cable such as indoor, outdoor, temperature range, ingress protection of the mated connector and of your device.

Use the table shown on page 4.

Part number coding

Step 2: Select connector size

B, K, T, S or E

Use the section (mm

) or the AWG of your cable wire to select the optimal contact diameter (values vary between

solder, crimp or print contact), see page 8.

Use this optimal contact diameter to determine the right connector size as well as the insert configuration, see page 6.

Part number coding

Step 3: Complete the part number

0, 1, 2, 3, 4, 5 or 6

Now that you know the series, as well as the insulator configuration, complete the part numbering system with the help

of the following table.

三星能否扭转命运看3月1日手机发布会

BI中文站 2月4日报道三星新年的真正开始时间可能得等到3月1日。届时，三星将在西班牙的巴塞罗那发布其新一代旗舰型智能手机，极有可能被命名为Galaxy S6。不过，外界已经觉察出今年三星旗舰机发布会的氛围与往年有所不同。三星目前处于困境之中，公司利润迅速下滑，而老对手苹果则是高奏凯歌，新一代手机产品屡创佳绩。与此同时，小米等后起之秀找到了制胜魔法，其所创造的手机产...[详细]
伺服驱动器有必要装滤波器吗

伺服驱动器有必要装滤波器吗？有太多的人问过青岛绿bo杰能这个问题。青岛lv波杰能的答案是肯定的。伺服驱动器确实有必要装MLAD-S伺服专用滤波器，但不是必须加滤波器，这是因为考虑到成本以及安装空间等现实问题。有很多的现场，伺服驱动器既没有安装MLAD-S伺服专用滤波器，也没有装MLAD-SR伺服专用电抗器，完全就是裸奔，也没有遇到出现谐波干扰问题，或者是根本就没有意识到谐波感染问题的存在，...[详细]

如何测量电源的纹波纹波测量点和示波器要求

今天聊一聊如何测量电源的纹波。 1、纹波的测量点要求纹波测量点要选择靠近负载的地方，例如CPU的供电管脚上的去耦电容上。 PDN是一个网络，主板上一个电源平面的不同的地方纹波是不一样的，建议选择最远，负载最大，环境最恶劣的地方。如果一个电源网络同时给多个耗电大的IC供电，这几个大的IC电源管脚都需要测试纹波水平。 2、示波器要求电源走线上有很多电容，寄生参数，形成了一个类似的低通滤波器...[详细]
