Lemo Circular Connector, 4 Contacts, Cable Mount, Plug, Male, IP50, 1B Series

From Lemo, a range of industrial circular metal connectors from the 0B and 1B series. Designed for cable mounting, the straight plugs feature a unique push-pull self-latching mechanism for safe and secure mating. Compact in design, the industrial circular connectors are G coded for higher contact density and prevent contact miss alignment. With 360° shielding for enhanced EMI performance, the 0B and 1B series of cable connectors are ideal for high accuracy and interference-free data and signals. Cable mount plugs mate with a panel or PCB sockets.

Lemo Push-Pull Self-Latching Connection System

The self-latching system is a simple and effective retention solution, providing complete protection against vibration, shock or any pull on the cable.

Engaging the system

To initiate the self-latching system the plug is simply pushed axially into its mating half. Once firmly latched in place via the internal latches the connection is virtually impossible to break. No amount of pulling on the cable or any other part of the connector body will release the two parts.

Disengaging the system

If the connection needs to be broken, a simple axial pull on the connector’s outer body release sleeve unlatches the internal mechanism. The plug can then be withdrawn from the socket separating the two halves.

• IP 50 ingress protection when mated
• Wide temperature range -55° C to 250° C
• G coded for connector alignment
• A secure push-pull self-latching mechanism
• 360° screening for full EMC shielding
• Solder termination
• Gold plated brass contacts
• 2, 3, 4, 5, 6 and 7 pole variants

Due to the connector’s compact size, the shielded plugs are ideal for applications in the industrial electronics sector. Some of the most common areas are

• Test and measurement equipment
• Sensors, switches, and actuators
• Instrumentation
• Medical devices
• Audio / video
• Automation

With an IP50 rating, the 0B and 1B series by Lemo are only suitable for indoor applications that are not exposed to the elements. They are moderately dustproof, but not waterproof and should therefore not be used around water or used in harsh environments

Q - How robust are the connectors?
A - The Lemo 0B and 1B series of circular connectors are manufactured from high-quality engineering materials. Although small in size they are incredibly resilient.
