PEC18SACN, also known as JST-XH, is a range of rectangular connectors with header, male pins and hardware. The PEC18SACN application field includes automotive, medical, consumer electronics, industrial, aeronautics and defence.

A PEC18SACN connector typically has a minimum of three circuits and a maximum of 14 circuits, with each circuit customizable. The male pins protrude only 1.50mm over the body, allowing for a low profile and assembly into confined spaces. Furthermore, due to its increased reliability and robustness, the height of the connector can remain the same even when used with up to 14 circuits. The discreet low profile connector can fit seamlessly into the end product in applications such as consumer electronics and medical.

The type of pins used with the PEC18SACN range of connectors are made from tin brass, and are surface mountable with surface mount technology (SMT) and through-hole technology (THT). This enables the pins to be mounted on the board without soldering, making it a quick and cost-effective assembly. This is also beneficial in applications such as automotive, industrial and medical, where components must be replaced in a short time-frame for minimal disruption. The insulation displacement connection (IDC) process is used with these pins, which allows them to clamp down on the wires when connected with a double wire in a single entry. In addition to this, the PEC18SACN connectors use a simple three-point locking mechanism along with a metal post, which increases the contact reliability and prevents connection failure within a short time-frame.

PEC18SACN connectors are extremely popular due to their electrical characteristics, which include a nominal current of 4A (max), an additional 1A surge current (current that can be passed through momentarily), a contact resistance of less than 10mΩ, and insulation resistance of more than 1000MΩ. An operating temperature range of -25ºC to +85ºC means that the PEC18SACN connector can be used in various applications for a long duration without any risk of failure from high temperatures.

The working principle for the PEC18SACN involves a two-piece construction, with the pins being housed within the header and the display elements housed within the housing. The pins and housing use a keyed mechanism, which allows for the secure connection of mating parts. The pins and sockets are soldered and then heat-staked inside the housing. The pins are made from tin-brass, which is corrosion resistant and also abrasion resistant. This allows the pins to connect properly and make secure contact with the mating parts. The pins have a groove underneath their heads, which act as a locking mechanism when inserted into the housing. The pins also have a pre-moulded insulation bottom, which helps reduce any potential crosstalk or electromagnetic interference.

The PEC18SACN is the most popular solution when it comes to a low profile, reliable and quick to assemble connector. It’s quick to assemble, easy to install and offers a high level of contact reliability. Its discreet low profile design helps keep the connector hidden when inserted into the mating piece, making it ideal for use in practical applications such as medical, automotive and consumer electronics. Its extensive range of electrical characteristics and operating temperature range ensures that the PEC18SACN connector is suitable to use in various industries.
