MTA-100 Connector Kits
MTA-100 Connector Kits

TE Connectivity product managers and I have recently collaborated to create a new line of AMP connector MTA-100 Deluxe Kits as for MRO (Maintenance, Repair and Operation) solutions.

These kits show off many capabilities of the TE Connectivity MTA-100 product line. Our initial challenge was to choose which product types to include. With all of the numerous header types, how could we show a good representation of sample parts without using every header available? The solution was to feature: Friction Lock, Shrouded, Polarized and Narrow Flat headers of the MTA-100 wire-to-board and wire-to-wire connector family.

Friction Lock headers are good for strength of connections and also for the fact that you will know once a connection is made as it will snap into place. Shrouded headers use four sided fully-shrouded header. The purpose of shrouding is to prevent mismating when mating a connector onto a live board. Polarized headers feature tabs which will not allow incorrect mating between contacts which is helpful for quality control purposes. Narrow Flat headers are great for small spaces due to their low profile.

The MTA-100 product line offers multiple circuit sizes, specifically 2 circuits through 28 circuits. Once again, for the purpose of space, I chose 3 different circuit sizes: 2, 4 and 6. These were chosen based on the relative popularity of their sizes. In addition, multiple wire gauges are available (28-22 AWG) and for this kit, I chose the largest wire gauge of 22, once again due to product popularity.

A key feature in the MTA-100 family is color coded housings for each wire gauge. Imagine being able to match up a large container of spare parts easily simply by their color. For example, all 22 wire gauge parts would be colored red. However, for all wire gauges with high temperature applications, all connectors are colored black.

In addition, the IDC (Insulation Displacement Contacts) connector feature is one-step termination without the need to strip wires. This is helpful to insure against poor stripping when using hand tools. The two types of connectors offered are closed end and feed through. “Closed end” are for wires ending at the Printed Circuit Board while “feed through” are for wires continuing through the connector.

If you are looking to use MTA-100 22AWG connectors for your business, I would suggest looking into kit no. 4-2110855-0 for a broad representation of parts within the family.

You'll find these and other Waldom Electronics kits at The site is easy to use and navigate, allowing you to select kits by the following: Product Type, Solution, TE Brand, Application, Industry and Most-Popular. Once your kit is selected, a kit details page will be shown displaying the description, bill of materials, and links to related kits or products.

To order additional MTA-100 Deluxe connector kits, access the kit details page of the specific kit, simply select the green “Check Inventory”, enter the kit part number, select “Search” which will then display the name of the authorized distributor(s), quantity on hand, current stock, etc.

These are just the types of kits engineers, technicians, schools, and home workshops can put to good use. Kits can only be purchased exclusively through the following Waldom Electronics Authorized Distributors: Allied Electronics, Arrow, Avent, Digikey, Future Electronics, Heilind, Master Distributors, Mouser, Newark Electronics, Online Components and TTI.
