In the electronic control systems of modern commercial vehicles, construction machinery, and specialty vehicles, connector reliability is a key factor in ensuring vehicle safety and proper operation. TE Connectivity’s SUPERSEAL 1.0mm series connectors, with their high-density design, IPX7 waterproof rating, and exceptional weather resistance, have become a widely adopted connectivity solution for vehicle control modules and engine control units (ECUs) worldwide.
Shenzhen Mingjiada Electronics Co., Ltd. maintains a long-term stock of 2388688-1. This model is a 34-pin through-hole male pin header from TE Connectivity’s SUPERSEAL series. It is an authentic, factory-direct product available from our dual warehouses in Shenzhen and Hong Kong, and we support both small-batch sample orders and large-volume production orders.
I. Product Overview: Designed for Harsh Automotive Environments
The 2388688-1 is a 34-pin, 4-row, straight-insert male pin header in TE Connectivity’s SUPERSEAL 1.0mm connector system, designed for through-hole soldering onto PCBs.
This connector is specifically designed for harsh environments in high-density PCB applications that require sealing and reliable connections. It is particularly suitable for engine control units (ECUs) and body control modules in commercial vehicles, off-road vehicles (such as construction and agricultural machinery), and specialty vehicles. Its IPX7 waterproof rating and wide operating temperature range (-40°C to +125°C) ensure stable performance even in harsh environments such as engine compartments with high temperatures, high humidity, and high vibration.

III. Core Technical Features
1. IPX7 Water Resistance Rating
Model 2388688-1 features IPX7 water resistance, capable of withstanding brief immersion (1 meter depth for 30 minutes), effectively protecting PCB-side connections from moisture intrusion. It is an ideal choice for high-risk areas prone to water exposure, such as engine compartments and undercarriages.
2. High-Density 34-Pin Design
The compact 4-row, 34-pin layout enables high-density signal and power connections within a limited PCB area, meeting the growing I/O demands of modern vehicle ECUs.
3. Wide Temperature Range and Weather Resistance
With an operating temperature range of -40°C to +125°C, it adapts to extreme environments ranging from sub-zero to high temperatures. Combined with a thermoplastic insulated housing and gold-plated copper alloy contacts, it ensures continuous and reliable electrical contact.
4. Robust Mechanical Structure
The locking ramp mechanism provides secure mating retention and excellent vibration resistance.
Board guide and mounting flange features simplify PCB assembly alignment and enhance mechanical retention strength.
The four-wall shielding design effectively protects the terminals from physical damage and misinsertion.
5. System-Level Design
The 2388688-1 is a straight-insertion pin header designed for use with the corresponding 2389578-1 receptacle housing. It features Keying 1 and an upper locking mechanism.
IV. Major Application Areas
Commercial and Special-Purpose Vehicles: Engine Control Units (ECUs), Transmission Control Modules (TCUs), and Body Control Modules (BCMs) for trucks, buses, construction machinery (excavators, loaders), and agricultural machinery
Off-Highway Vehicles: Electronic control systems for mining equipment, port machinery, and forestry machinery
Industrial Automation: Outdoor control equipment requiring IP67/IPX7 protection ratings; industrial sensor connections
Other High-Reliability Applications: Rail transit, marine electronics, and control board connections for new energy storage systems
