What F Series IP68 Waterproof Connectors are designed to solve

Direct answer: F Series adds environmental sealing to a quick-mating circular format. The final protection level depends on the exact plug, receptacle, backshell, cable and mating condition.

The best result comes from matching the connector and cable to the complete system—not selecting by diameter or appearance alone. This page organizes the decisions an engineer, buyer or system integrator needs to make before requesting a drawing or quotation.

LMConn groups compatible formats by locking method, interface size, contact arrangement, installation method and cable construction. This makes it possible to compare standard options while keeping project-specific details such as pin mapping, cable length, labels and validation requirements under controlled revision.

Manual-derived technical content

Catalog-derived parameters with original LMConn visuals

The following technical values are taken from the supplied source manuals rather than inferred from general connector practice. The accompanying image is an original LMConn presentation visual and is not a model-specific engineering drawing. Family-level data summarizes the catalog; ordering dimensions and electrical limits must still be checked against the exact model row and contact layout.

Product appearance varies by shell size, contact layout, mounting and cable configuration. Request the current model drawing and approved sample for final verification.

Engineering selection guide

  1. Confirm required IP rating in mated and unmated states. Record the requirement in the interface-control drawing or RFQ so it can be verified.
  2. Specify cable jacket and outside diameter. Record the requirement in the interface-control drawing or RFQ so it can be verified.
  3. Choose panel sealing method. Record the requirement in the interface-control drawing or RFQ so it can be verified.
  4. Check temperature and chemical exposure. Record the requirement in the interface-control drawing or RFQ so it can be verified.
  5. Plan protective caps where connectors remain unmated. Record the requirement in the interface-control drawing or RFQ so it can be verified.

Information that controls the design

DecisionQuestions to answerWhy it matters
ElectricalSignal, protocol, voltage, current, contact count and shielding?Controls insert layout, contact size, cable and test plan.
MechanicalMounting, straight/angle exit, panel thickness, mating access?Controls envelope, cutout and serviceability.
EnvironmentDust, water, chemicals, temperature, vibration and mating cycles?Controls sealing, material and strain-relief choices.
CableStatic, flex, torsion, conductor size, jacket and outside diameter?Controls backshell, gland, bend radius and lifetime.
QualityInspection, electrical test, labels, traceability and packaging?Creates an objective acceptance standard.

Important: Ratings differ by exact part number, contact layout, cable and assembly condition. Values shown on a family page are selection guidance, not a substitute for the approved product drawing and datasheet.

Typical applications and design priorities

Outdoor sensors

For outdoor sensors, engineers normally prioritize connection security, routing space and service access. Document the mating part and operating conditions so the connector, cable and termination can be evaluated as one system.

Marine-adjacent equipment

For marine-adjacent equipment, engineers normally prioritize signal integrity, environmental protection and repeatable installation. Document the mating part and operating conditions so the connector, cable and termination can be evaluated as one system.

Washdown machinery

For washdown machinery, engineers normally prioritize connection security, routing space and service access. Document the mating part and operating conditions so the connector, cable and termination can be evaluated as one system.

Environmental monitoring

For environmental monitoring, engineers normally prioritize signal integrity, environmental protection and repeatable installation. Document the mating part and operating conditions so the connector, cable and termination can be evaluated as one system.

Mobile systems

For mobile systems, engineers normally prioritize connection security, routing space and service access. Document the mating part and operating conditions so the connector, cable and termination can be evaluated as one system.

How to compare candidate products

Begin with non-negotiable interface requirements, then compare environmental and assembly details. Do not use a single headline rating as the sole decision. A suitable candidate should match the mating geometry, contact map, electrical load, cable construction, mounting envelope and maintenance method.

For replacement projects, send photographs only as supporting information. Measurements, existing part numbers, panel cutouts and pin assignments are needed because many circular connectors have similar external shapes. For new designs, reserve space for the connector body, coupling action, minimum cable bend radius and an operator’s hand or assembly tool.

RFQ checklist

  • Target quantity, prototype quantity and annual demand.
  • Connector family, mating component or interface drawing.
  • Contact count, gender, coding, keying and pin assignment.
  • Voltage, current, signal type, network protocol and shield strategy.
  • Mounting method, panel thickness and available installation space.
  • Cable type, length, conductor size, flex requirements and jacket material.
  • Ingress protection, temperature, vibration and chemical exposure.
  • Required tests, labeling, documentation and packaging.

Frequently asked questions

What is F Series IP68 Waterproof used for?

F Series adds environmental sealing to a quick-mating circular format. The final protection level depends on the exact plug, receptacle, backshell, cable and mating condition. Common uses include outdoor sensors, marine-adjacent equipment, washdown machinery. Final suitability depends on the selected part number and operating conditions.

How do I select the correct IP68 push pull connector?

Start with the mating interface, electrical function and environment. Then confirm mounting, contact layout, termination, cable diameter and keying. The selection checklist on this page captures the minimum information needed for an engineering review.

Are all IP68 push pull connector products interchangeable?

No. Products that look similar may differ in thread, shell size, keying, contact layout, insert orientation, sealing and dimensions. Always compare the complete dimensional drawing and mating-part definition.

Which specifications should I send for a quotation?

Send quantity, drawings or mating part, contact count, pinout, voltage and current, signal or protocol, cable type and length, environmental rating, mounting style and any testing or labeling requirements.

Can LMConn configure a custom version?

Configuration can cover contact layout, cable length, connector orientation, pin mapping, shielding, overmolding, labels and packaging where technically feasible. A drawing review is required before production.

How is the final part verified?

Verification should be defined by the project and may include dimensional inspection, continuity, insulation resistance, contact resistance, high-potential testing, shield continuity and visual checks. Required tests must be agreed in the specification.
