Lighter and more cost-effective than a traditional circular connector, the Pulse-Lok series of circular cable assemblies and connectors offers field-proven, rugged solutions for your system’s needs.
Utilizing our intuitive auto-coupling latch mechanism, Pulse-Lok connectors assure the user of a secure connection with visual, audible and tactile confirmation of engagement. Unlike the traditional push-pull connector type, whose latch mechanism may increase the mating and un-mating forces of the cable assembly, our coupler contributes almost no additional force to the mating process.
Once engaged, our retention features ensure a safe, secure connection that protects against disengagement due to unintended pull on the cable assembly. During disengagement, our custom connectors and assemblies are designed to actually assist in un-mating the product by driving the connectors apart when actuated.
Pulse-Lok Circular Connector Highlights
From 1 to 128 positions:
Whether you need seamless data transmission across multiple channels or a single line of power, Pulse-Lok has you covered with a wide range of contact arrangements designed to meet various application requirements.
Many off-the-shelf varieties available:
Five shell sizes with multiple housing materials, including cast-metal and metal-plated plastic, allow you to custom configure the right solution for your need. These options provide durability, reliability and resilience for different environments and applications.
Accommodation for multiple contact arrangements:
Pulse-Lok optimizes the design of your interconnect solution by accommodating traditional pin-and-socket, compression, fiber-optic contact technologies and hyperboloid contact. This versatility makes it suitable for a wide range of power and signal connectors.

Pulse-Lok® Circular Connector FAQs
Pulse-Lok® circular connectors use an auto-latching mating style to ensure a secure connection to the devices and cables they are used with. This mechanism provides visual, audible and tactile feedback to confirm a secure connection.
These connectors are versatile and reliable, making them suitable for various medical devices. Some common applications include cosmetic surgery, defibrillation, electrophysiology, electrosurgical devices, imaging, minimally invasive surgery and patient monitoring.
While many medical connectors use metal bodies for durability, Amphenol Alden’s plastic connectors use a rugged material designed for the rigors of medical applications. In fact, they’re just as durable and reliable, only lighter. This reduces strain on the cables and devices, making them easier to handle and use.
