SCT3700 Series is Scondar’s Line of Low Price, High Quality Molex EL 3.7mm Pitch Wire-to-Wire Connectors

Scondar offers SCT3700 Series as a replacement and cheaper alternative of Molex EconoLatch 3.7mm pitch wire-to-wire connector in a complete package including the male housing, female/receptacle housing, female terminal and male terminal, all manufactured with precision-fitting and durability ensuring accurate mating in electronic devices.

Molex EconoLatch supports up to 11.5A of current per circuit allowing quick swapping of wired terminals for disruption-free operations in consumer, automotive and industrial applications. Scondar’s economy power connectors are designed with up to 9 positions, so your product can reliably deliver power even when space is limited.

EconoLatch is truly an state-of-art connector as it has a distinct feature of configuring identical circuit connections in a single wire harness while maintaining male and female parts in proper order without mismating. This is especially common when multiple polarized housings are involved in one harness.

Prominent Circuit Identifiers at the Rear Housing and Receptacle and Plug Housings

These identifiers ensure that there is a correct order in inserting/pairing crimped leads to the circuits.

Fully Polarized Key Feature with Latching Orientation

Prevents mismating to facilitate assembly

Well-Designed Crimping Feature

The crimp are designed with a circular pattern allowing flexible orientation options for quick insertion and assembly.
The crimps are well engineered to be air-tight, preventing oxygen and moisture from reaching the metals, causing corrosion. Thus, the connector can be easily removed from the head without holding the wires.

Positive locking mechanism

To facilitate a secure connection without dropouts, a positive locking mechanism feature greatly enhances wire-to-wire mating connections.

Equipped with Reduced Mating Force (RMF) Solutions

The different wire-to-wire connector types are equipped with RMF solutions for lower friction solution between the contacts of the device and the socket, making insertion and removal of the device easier, while at the same time eliminating the need for the complex mechanisms such as in ZIF sockets.

Dual terminal locking lances

This feature of the terminal locking lances is notable for providing contact stability when inserted in the connector housing. The dimpled terminals are also substantial in providing enhanced contact reliability and optimized electrical performance.

Material and Packaging of Molex EconoLatch 3.7mm Pitch Wire-to-Wire Connector

Using a UV-Resistant Thermoplastic Material for Enhanced Connector Performance

The housing components are injection molded Nylon66,UL 94V-0. These thermoplastics are scientifically proven to resist UV-radiation than the normal plastics, ensuring that the connectors are well-protected, reducing the chances of early degradation and increased cycles/minute of the connector subjected to harsh environments.

Tape and Reel Packaging for SMT Components

Scondar uses a state-of-the-art tape and reel equipment to package a variety of components.

The tape and reel packaging strip has accurately sized cavities for the terminal height, width and depth, securing the them from the environment and maintaining consistent position during transportation.

You can expect that your wire-to-wire connector package is undisturbed during the trip and has maintained its vitality even during your production stages, which is why a lot of our customers has raved about our product for both cheaply-priced and, at the same time, resembles the Molex EconoLatch 3.7mm pitch wire-to-wire product in performance and quality.

The complete package will include the following:

Female terminal: 10,000 pcs/reel, brass material and tin-plated finish
Male terminal: 10,000 pcs/reel, brass material and tin-plated finish
Female Housing (Nylon 66, UL94V-0 500): 1000pcs/bag
Male Housing (Nylon 66, UL94V-0 500): 1000pcs/bag
