Amphenol Communications Solutions AMPMODU Series Straight Through Hole PCB Header, 4 Contacts, 2.54 mm Pitch, 1 Row HE14

TE Connectivity AMPMODU HE14 Series PCB Header, model 281695-4, is a highly reliable straight through-hole connector engineered for wire-to-board signal transmission needs. This header features 4 male contacts arranged in a single row with a precise 2.54 mm pitch, making it suitable for a broad range of industrial, commercial, and electronic applications requiring compact yet robust interconnection.

Housed in blue high temperature UL 94V-0 rated thermoplastic, the connector is designed to withstand challenging environments and provides superior mechanical protection. The shrouded structure minimizes risk of pin damage and mismating, crucial for field or factory installations. Protective shrouds include an integrated friction lock, ensuring each connection remains secure even during repeated mating cycles.

Contact elements are made of phosphor bronze and finished with tin plating, offering reliable conductivity and corrosion resistance. The component is capable of operating with circuit currents up to 3A and voltage up to 500V, while the solder termination ensures strong mechanical and electrical connection to the PCB. A tail pin length of 2.79 mm is optimized for secure insertion into the board, and the straight mount format is suitable for automated assembly.

The polarized housing further reduces installation errors by preventing reverse mating. Designed for a wide temperature range from -40°C to 105°C, the header is suitable for operation in industrial, automotive, laboratory, and electronic settings. Typical use cases include automotive control units, test and measurement instruments, computers, telecom systems, medical electronics, storage devices, and consumer appliances.

This header mates specifically with AMPMODU HE14 IDC receptacles for discrete wires or ribbon cables of matching 2.54 mm centreline, ensuring comprehensive compatibility within the AMPMODU HE14 interconnect system. The AMPMODU HE14 system is recognized for economic, dependable automation and control connectivity across many industries.

Engineered for ease of PCB assembly, signal integrity, and long service life, TE Connectivity’s 281695-4 meets stringent requirements for quality and reliability. It is an outstanding choice for designers and engineers seeking a proven PCB Header solution for wire-to-board interfaces.
