Samtec TMM Series Right Angle Through Hole Pin Header, 4 Contacts, 2 mm Pitch, Unshrouded, 1 Row, Liquid TMM-104-01-T-S-RA

The Samtec TMM-104-01-T-S-RA is a right angle through hole pin header designed for wire-to-board connectivity in electronic, industrial, and PCB assembly applications. Featuring 4 contacts arranged in a single unshrouded row with a 2 mm pitch, this header is engineered for precise and compact board designs where lateral connection is preferred. The right angle orientation makes it ideal for tight spaces and modular layouts, improving ease of access for soldering and circuit inspection.

This pin header utilizes a liquid crystal polymer housing for enhanced strength and resistance to temperature extremes, accommodating operating conditions from -55°C up to 105°C. Contacts are made from phosphor bronze and are tin-plated, guaranteeing stable signal integrity and corrosion resistance across a wide voltage (281V) and current (3A) range. The tail pin length of 3.5 mm and a mating pin length of 3.2 mm ensure optimal coupling and mechanical stability with matching connectors.

The TMM series unshrouded design facilitates flexibility during assembly without restricting access, making it easy to handle, rework, or inspect during manufacturing and quality control processes. With wire-to-board connector system architecture, it supports a large variety of low-profile pin counts and terminal options leveraging the FleXYZ™ design flexibility in three axes for customized layouts up to four rows wide and 200 pins.

Mounting is ensured by reliable through-hole solder termination, providing a durable and secure connection to PCBs. The solder termination type helps achieve a robust mechanical and electrical interface that withstands repeated service and handling in laboratory, manufacturing, and field installations.

Industrial applications include electronics assembly, power and signal distribution in PCB designs, automation controls, instrumentation panels, and prototype development. With high voltage and current ratings, it’s suitable for both signal and low-power interfaces in commercial electronics, laboratories, HVAC controls, and other environments requiring compact, reliable connections.

Samtec TMM-104-01-T-S-RA delivers essential connectivity where space, reliability, and flexibility are paramount. Explore more PCB Headers and advanced connector solutions in the Electronics & Electricals category on EnvMart.
