signal|mate - M16-A Circular Connectors
Our signal|mate - C091 series circular connectors are recognized industry standard for compact signal and power transmission. The M16-A series provides IP40 protected metal connectors with industry standard M16 screw locking and is a reliable and cost efficient interconnect solution for indoor applications.
The series features 2-8 and 12-19 pin connectors. For contact plating, our customers can choose between silver, flash gold (NEW) and hard gold for crimping and soldering. Furthermore, there are different solutions for direct connection to the PCB.
Product features:
Protection class IP40 when mated
M16 screw locking according to IEC 61076-2-106
Metal housing with shielding connection (via clamp)
13 contact arrangements on a shell size of ⌀ 18mm
From 2 to 19 pin for signal and power transmission
Current transmission up to 10A at 300V AC/DC
Wire cross-section 0.05-1mm² / AWG 30-20
Colored backshells available as accessory
Qualified according to UL1977 / certificate number E63093
M16 circular connectors of the signal|mate series are used e.g. in the fields of industrial automation, lighting, control systems, camera technology as well as measurement. The connection solutions are compatible with competitor products.

Frequently Asked Questions
The following components are required for a complete solution:
Cable connector and counterpart of the opposite gender (socket/device part)
Release tool FH 0300 091 and installation wrench N 45 091 000 1
depending on the application: protective cover
For crimp versions, the crimp contacts and the crimping tool must be ordered separately.
We have great experience in the development and production of cable assemblies and complete devices, especially on the machine side (distribution boxes, PCBs, covers). Send us your request to industrial@amphenol.de and we are happy to support you!
In addition to 180° dip solder contacts in three length variants, there are also options for 90° connection, including a flange that can be placed directly on the PCB. We also offer a solution where the PCB only needs to be slided into the back side of the receptacle (on request). Alternatively, our flying pigtail assemblies with PCB connectors allow more flexibility and failure tolerance.
With M16A connectors, the braided shield can be connected to the metal housing using a shield clamp. If a high shielding capability is required, we recommend our M16D+ cable connectors with 360° shielding and 40db attenuation.
Even though the contact resistance is slightly higher with crimp connections, this connection technology has established itself over soldering. Particularly for large quantities, investing in automatic crimping machines pays off in terms of material costs, workload and quality assurance. We have many years of experience with crimping technology and offer a broad portfolio of crimp contacts across all series, turned and stamped, loose and on reels.
Environmental influences often cause oxidation on the surface of silver-coated contacts, which is indicated by a dark coloration. The oxide layer has no effect on functionality and is automatically rubbed off when plugged in. In use, the oxide layer usually burns out at a load > 24V or 200-300mA. If smaller currents flow, we recommend gold-plated contacts to keep the contact resistance low in the long term.
Our M16A/B connectors usually come with a black plastic housing. With the backshells T29935109C / T29935119C / T29935129C / T29935139C, the color of the grommet version can be adapted to blue, red, yellow and green. We also offer color matching of other plastic and metal components depending on your yearly demands.
As an alternative to the ring nut, our M16 receptacles can also be equipped with an SW20 hexagon nut (part number T 0422 060 9). We are also happy to supply the component directly with a hexagon nut depending on your yearly demands.
In addition to the standard 5 and 7 pole contact layout, there are also stereo versions. Historically, these were used to transmit sound, but today customers usually use other connector solutions (Audio series). The solder connection is typical for the application, which is why these layouts are not available with crimp contacts. With the stereo layouts mechanical coding (Poka Yoke) can be realized.
During a transfer of the production facility in 2010, the "U" was introduced at the end of the part number for clear traceability. The dimensions, material and technical function remained completely unchanged during the process. Today, the "U" is an integral part of the part number, regardless of the supply chain.
