DB37 connector3

Pandy's high-density  37 pin d sub connector belongs to the standard D-SUB series. Featuring a solder-cup wire-to-board structure, it is specifically designed for custom cable harness assembly and serves as a classic industrial interface for centralized multi-channel signal transmission. Pandy is a prominent Chinese manufacturer specializing in connectors, recognized as an influential producer of industrial control and medical cable harnesses, as well as D-SUB electronic connectors. The dsub connector db37 male is widely used across various industries make in pandi.

Product Structure and Core Features of the 37-Pin d sub connector

1. Layout Specifications

The 37 contacts are arranged in two rows, available in male (pin) and female (socket) configurations. The rear features solder-cup terminals where wires are directly soldered and secured, making it ideal for custom-made cable harnesses.

2. Advantages of Wire-to-Board Soldering

The solder-cup structure ensures a robust solder joint that is highly resistant to vibration and prevents accidental disconnection. It supports soldering with various wire gauges, offering flexibility for custom cable applications. Compared to crimp-style connectors, it is particularly well-suited for small-batch and non-standard cable harness production.

3. Protection and Shielding

The metal D-shaped shell provides EMI (Electromagnetic Interference) shielding. The mounting flange features standard screw holes and can be paired with locking screws to prevent loosening after mating, effectively eliminating signal interruptions in high-vibration environments.

4. Contact Technology

Contacts are available in machined or stamped pins and feature gold plating to reduce contact resistance, enhance oxidation resistance, and ensure excellent mating cycle durability. The insulating housing is made of high-temperature engineering plastic, offering superior heat resistance during soldering.
