Binder integrates dip solder contacts in M12 L-coded panel mount connectors
Compact, standardised connectivity for a power supply in industrial automation is provided with the 823 series M12-sized L-coded panel mount connectors, said binder.
The 823 series connectors’ dip solder contacts are suitable for reflow soldering on PCBs in automation applications that are subject to installation restrictions, said binder. They are also suitable for hand soldering and wave soldering. In reflow soldering applications, they serve as electromechanical interfaces in the power supply of industrial devices up to 63V DC and 16A, making them suitable for industrial Ethernet applications in the Profinet environment.
Miniaturisation means that devices such as sensors, actuators, controllers or industrial computers are shrinking while their functionality is increasing. At the same time, power requirements are growing. The L-coded 823 series M12 connectors are a space-saving alternative to the 7/8-inch models conventionally used for the power supply.
The 823 series includes two-piece male and female panel mount connectors. Each consists of a mounting body and a socket housing, which are not permanently connected to each other. Assembly and disassembly of the PCB are simplified compared to when using single-piece components, said binder. The mounting body is soldered to the board during assembly and the socket housing is attached directly to the device. Soldering can therefore be done without the housing. Another benefit is that solder connections are not subjected to torques due to the housing assembly, reducing the stress load on both components to contribute to the elimination of failure sources.
The connectors are IP 68 when mated and suitable for both front and rear panel mounting. The PCB cannot be fixed to the housing by the conventional two-part dip solder panel mount components but should be mounted separately to the housing. This is a significant difference from single-piece versions, which in the case of very small PCBs can be used to attach these to the device housing, binder noted.
Distinctive features of the 823 series arw a buried and captive O-ring with metallic blocking, and an O-ring between the socket housing and contact body that prevents sealing compound from leaking when the user’s housing is being sealed. A seal to the cable part is also provided on the socket housing to guide it into place, even in the case of thin-walled mounting flanges.
