Velok compact rectangular connectors are engineered to simplify power connections in demanding settings such as aircraft interiors and industrial systems. They are small and lightweight, yet built to handle low- to medium-power requirements with ease. The connectors use a spring-loaded push-pull latch that allows quick, single-handed mating and release without any tools. Each connector also provides a clear visual lock indicator, so technicians can immediately confirm when the plug and receptacle are fully engaged – reducing the risk of partial mating or connection errors.
The robust rectangular housing of a Velok connector incorporates a scoop-proof design. This means the contact pins are shielded by the housing during mating, preventing bent contacts or electrical shorting even if the connector halves aren’t perfectly aligned. The connectors are moulded from durable Polyetherimide plastic (Ultem), giving them a broad operating temperature range and strong resistance to chemicals. An IP69 sealing rating ensures these connectors are completely dust-tight and can withstand high-pressure water jets, making them suitable for harsh or outdoor environments. Multiple keying options are available as well, allowing different Velok connectors to be uniquely keyed to avoid any chance of mismating in complex wiring setups. Additionally, an integrated boot ridge on the connector body lets users secure cable sheathing or boots directly, eliminating the need for separate backshells or clamps. Overall, the Velok series provides a reliable, easy-to-use solution for aerospace cabins, industrial equipment, transportation systems, and other applications requiring a compact yet rugged power connector that can endure tough conditions.

FAQs
for Velok compact rectangular connectors
Velok connectors use a spring-loaded push-pull latch mechanism. This design allows the user to simply push the plug into the receptacle to lock the connection and pull back to unlock. The latch provides a positive engagement so the connectors snap firmly together without needing twisting or threaded coupling, making mating quick and effortless.
The scoop-proof design means the connector’s housing is shaped to guide the plug into the receptacle in a way that the contact pins cannot accidentally hit the wrong surfaces. In practice, this prevents the pins from getting bent or causing electrical shorts even if you start to plug it in at an angle. The housing “scoops” and aligns the halves, ensuring the delicate contacts are protected during mating.
Velok connectors are built for use in harsh and demanding environments. Their IP69 sealing means they are completely protected against dust and can tolerate high-pressure water jets, so they are suitable for outdoor applications and equipment that undergo washdowns. The Polyetherimide (Ultem) housing withstands a wide temperature range and exposure to fuels or chemicals, which is ideal for aerospace cabin installations and industrial machinery. The sturdy latch also keeps them securely mated even under vibration or shock, making them reliable in vehicles and aviation settings.
The Velok series offers multiple keying configurations – essentially variations in the connector shell that act like unique “keys.” If you are using several Velok connectors in one system, you can choose different keying for each so that only matching plug/receptacle pairs will mate. This prevents an assembler from accidentally connecting the wrong connectors together. In practice, the keying positions greatly reduce the chance of wiring errors or damage from mismating in complex systems.
Each Velok connector has an integrated boot ridge feature around its rear body. This ridge provides a place to secure a cable’s protective boot or braided sleeving directly to the connector using a tie-wrap or clamp. Because of this design, you often do not need a separate backshell or strain-relief clamp – the cable jacket or sleeve can be tied off on the connector itself. It simplifies cable management and still gives a sturdy strain relief to protect the cable terminations.
The primary housing of the Velok connector is made from Polyetherimide, a high-performance thermoplastic branded as Ultem. This material was chosen because it can handle very high and low temperatures without degrading and is resistant to many chemicals (like fuels, oils, and solvents). Using Ultem for the connector body ensures that Velok connectors remain robust and reliable in extreme conditions. The contacts inside are made of metal alloys (chosen for conductivity and durability), but the specific contact material and plating will depend on the exact variant and is designed to carry the intended power loads reliably.
Velok connectors are intended for low to medium-power applications. In practical terms, this means they are suitable for supplying power to devices like lighting systems, small motors, avionics boxes, or other onboard equipment in vehicles and aircraft. They are not meant for ultra-high current transmission but rather for moderate power distribution where a compact, quick-disconnect solution is beneficial. For exact current and voltage ratings, it depends on the specific contact configuration and should be verified from the technical documentation, but typically these connectors will handle the power needs of aerospace cabin electronics and similar industrial uses.
