68691-420HLF

The 68691-420HLF rectangular connector is typically used in electronic applications where insulated chassis are required for protection or electrical isolation. It is designed for connecting multiple wires and cables, and sometimes two PCB boards together in an electrical system. This type of connector has male and female pin connectors, with a total of four pins.

Electrical Features

The 68691-420HLF connector has four positions, with one on each side of the connector, and each position has two pins. The pins are made of brass, which is silver-plated and the pins have gold-plated contact surfaces. The 68691-420HLF has an operating voltage of 250VAC and a current rating of 5A. It also has an insulation resistance of 500MΩ.

Mechanical Features

The 68691-420HLF connector has a working temperature range of -40°C to +110°C and the contacts are rated for 500 mating cycles. The connector has a body made of thermoplastic material, which makes it resistant to mechanical shocks and vibrations. It also has a positive locking system, which also ensures that the connector stays firmly in place.

Applications

The 68691-420HLF connector is typically used in electronic applications where insulated chassis are required for protection or electrical isolation. It is suitable for a range of applications including industrial machines, telecoms equipment, instrumentation equipment, and home appliances. It is also suitable for applications where low voltage and low current are required, such as telephone exchange equipment and lighting equipment.

Working Principle

The 68691-420HLF connector works on the principle of making and breaking electrical contacts. It has two pins on each side of the connector, one for making the contact and one for breaking it. When a connection is made, the two pins make contact and current flows between them. To break the connection, the plunger on one of the pins is released, and the pins break contact, interrupting the current flow. This type of connector is also known as a header connector.

Conclusion

The 68691-420HLF rectangular connector is a versatile and reliable connector that is suitable for a range of applications where insulated connectors are needed. It is designed for making and breaking electrical contact with two pins on each side of the connector. It has an operating voltage of 250VAC, a current rating of 5A, and an insulation resistance of 500MΩ. This type of connector is ideal for a range of applications such as industrial machines, telecoms equipment, instrumentation equipment, and home appliances.
