HTSW-140-05-S-D-LL

HTSW-140-05-S-D-LL connectors are a type of rectangular connector used primarily for wire-to-board and board-to-board applications. They may also be used to link switches, circuit breakers, and sensors. Because of their versatile design, they are a cost-effective solution for many application scenarios.

Design and Configurations

The HTSW-140-05-S-D-LL rectangular connector is designed in a 15mm x 10.15mm footprint and comes in three variants: single-row core, dual-row core, and high density dual-row core. Single-row core connectors consist of a single row of pins on a single side, while dual-row core connectors have two rows of pins on opposite sides. The high-density dual-row core variant has more pins than the dual-row core variant and is used most often in applications that require more densely packed pins for increased current or voltage capacity.

The HTSW-140-05-S-D-LL rectangular connector is available in a range of pin counts from 2 to 70 and has a pitch of 0.5mm. It has a friction-lock design and comes with a durable polycarbonate housing that is suitable for harsh environments. The pins are made of phosphor bronze and are rated for a maximum contact resistance of 15 milliohms.

Applications

The HTSW-140-05-S-D-LL rectangular connector is ideal for a wide range of applications due to its compact size and durable construction. It is most often used in automotive, aerospace, industrial, and consumer electronic applications. Some of the more common applications include:

• Power distribution
• Signal transmission
• Automotive audio and video systems
• Aircraft audio and video systems
• Industrial automation
• Security systems
• Robotics and mechatronics

Working Principle

The HTSW-140-05-S-D-LL rectangular connector has a simple working principle based on electrical contact pairs. When the male pin connector is inserted into the female housing, the contact pins on the male connector make contact with the corresponding contact pads on the female housing and the two electrical contacts form a low-resistance connection. This connection allows electrical current to flow from one side to the other with minimal power loss.

In some cases, the contact pins and pads may need to be stabilised, especially in vibration-prone applications. This can be done by using a self-locking mechanism that prevents the pin from coming out of the housing even when exposed to intense vibrations. The pins may also need to be secured using screws, clamps or other methods, to ensure a robust connection.

Conclusion

The HTSW-140-05-S-D-LL rectangular connector is an ideal choice for applications that need a small and lightweight connector with high current and voltage capacity. It comes in a variety of configurations, allowing it to be tailored to specific needs, and is cost-effective solution to many application scenarios. The working principle of the connector is based on simple electrical contact pairs, with optional stabilisation measures taken to ensure a durable connection in vibration-prone environments.
