Product Details
| Engineering Features & Specs | Technical & Assembly Advantages | Strategic Business Benefits |
| Unique DB9-Shaped Housing | Matches the footprint of standard D-Sub connectors, allowing for easy integration into existing D-Sub cutouts. | Hybrid Design Flexibility: Enables engineers to combine terminal block convenience with D-Sub mounting standards, reducing the need for custom enclosure modifications. |
| Integrated Mating Flange | Provides threaded holes for securing the mating plug via screws. | Anti-Vibration Security: Ensures the connection remains intact in high-vibration industrial environments, eliminating accidental downtime due to cable pull-out. |
| 90° Right Angle & Shrouded Design | Optimized for low-profile PCB layouts with 4-side protection for male pins. | Space-Saving Efficiency: Minimizes vertical height requirements in thin control boxes while protecting internal components from mechanical damage during assembly. |
| Snap-in Board Lock Mechanism | Holds the header firmly in place on the PCB during the soldering process. | Simplified Production: Reduces manual alignment time and improves soldering yields by preventing “component float” on the assembly line. |

Q1: What makes the 1841857 “DB9 Shape” useful?
A: The 1841857 is part of the POWER SUBCON series, designed to fit into standard D-Sub 9-pin cutouts. This allows you to replace a 9-pin serial port with a high-current 3-position terminal block connection without redesigning your device’s front panel or chassis.
Q2: Is this header compatible with any 3.50mm terminal plug?
A: While it uses a standard 3.50mm pitch, it is specifically designed to work with Phoenix Contact MC series or dedicated POWER SUBCON plugs. For maximum security, we recommend using the mating plugs that feature screw-locking to utilize the header’s flange.
Q3: Can it withstand high-temperature soldering?
A: Yes, the housing is made of high-quality Polyamide (PA) with a UL94 V-0 flammability rating, suitable for standard wave soldering processes used in industrial PCB assembly.
