<div><strong>SQT-135-01-L-D Application Field and Working Principle</strong></div><div></div><div><span style="font-weight: 400;">The SQT-135-01-L-D model is a two-piece, low-profile, right angle rectangular connector with an optically isolated connection. Primarily designed for applications in the medical sector, such as pacemakers, the two-piece connector eliminates the need to create complicated, solder-down assembly which saves time and money. The SQT-135-01-L-D connector also simplifies the process of replacement by allowing for quick mating and de-mating, meaning components can be easily removed for maintenance without requiring external tools and it is also highly resistant to vibration and shock.</span></div><div>&nbsp;</div><div><span style="font-weight: 400;">In regards to the terminal options, the model features two 10-32 dual-row terminals. This allows for the connector to handle up to 70 A current and up to 45 V per position. The dual-row features prevent improper insertion, further increasing the safety of the connector. Additionally, the terminals provide reliable contact performance to ensure efficient operations for a prolonged period of time. </span></div><div></div><div><span style="font-weight: 400;">The SQT-135-01-L-D’s plastic housing is made from a polyamide material that is able to resist high temperatures of up to 125°C. In addition, the connector is also designed with IP67 class protection and keying features to ensure safe connections.</span></div><div></div><div><span style="font-weight: 400;">The working principle of the SQT-135-01-L-D connector is quite simple. The two-piece connector consists of a male header and a receptacle, with each component featuring two rows of terminals. When the male header is mated into the female socket, the two terminals from each row make contact, allowing for a secure and optically isolated connection. </span></div><div></div><div><span style="font-weight: 400;">In conclusion, the SQT-135-01-L-D is an ideal general use, low-profile, high-reliability rectangular connector for medical or communication applications. It offers superior contact performance as well as IP67 protection and the optically isolated connection provides reliable signal transfer.</span></div>
