Bayonet Circular Connectors: LPT Series Speeds Assembly with Positive Locking

New Sizes, Inserts, and Accessories for Flexible Design-In

Bayonet circular connectors are a proven choice for fast, reliable interconnects in harsh industrial environments. Amphenol Industrial Operations’ LPT Series brings military-style robustness to commercial and industrial applications, delivering quick positive coupling, broad insert layouts, and IP-rated sealing in a cost-effective package.

What Makes Bayonet Circular Connectors Ideal for Industrial Use

Bayonet coupling provides tactile, repeatable engagement with a quarter-turn action that speeds assembly and maintenance while resisting vibration-induced loosening. For buyers and OEMs standardizing across platforms, the LPT Series offers compatibility with common MIL-DTL-26482 Series I dimensions and panel cutouts, helping streamline qualification and reduce engineering time.

Rugged Construction for Harsh Environments

The LPT Series is engineered to perform where dust, moisture, and washdowns are common. Housing materials and gasketing are selected for durability and long service life, and the range supports IP-rated protection when properly mated and capped. For teams documenting ingress requirements, reference the IEC IP rating system to align connector selection with the target environment and cleaning regimen (learn more about IP ratings).

Versatile Insert Arrangements and Contact Options

From compact sensor runs to higher-current power drops, bayonet circular connectors in the LPT family cover multiple insert arrangements to fit signal, power, or mixed-layout needs. This flexibility simplifies platform reuse across product lines and reduces the number of suppliers and part numbers your organization must manage.

Fast Coupling, Positive Locking, Lower Assembly Time

Quarter-turn bayonet coupling reduces assembly cycle time on the line and speeds field service compared with threaded interfaces. Clear detents provide an audible and tactile “click” that gives technicians confidence under time pressure or in low-visibility conditions. The result: fewer reworks, faster swaps, and improved overall equipment effectiveness (OEE).

Designed for Maintainability and Inventory Efficiency

Common shell sizes, accessories, and backshell options help centralize spares and reduce stocking complexity. With bayonet circular connectors across multiple assemblies, OEMs and distributors can create rationalized kits that cut picking time and simplify field-service logistics.

Applications Across Multiple Markets

Typical uses include factory automation I/O, mobile and heavy equipment harnessing, rail and mass transit subsystems, renewable energy balance-of-plant, and power distribution cabinets. In each case, bayonet circular connectors provide a balanced combination of sealing performance, mechanical reliability, and quick serviceability.

Quality, Support, and Global Availability

Amphenol Industrial Operations backs the LPT Series with global manufacturing and applications support. Distributors benefit from an established, scalable line that is easy to position across markets, while OEMs gain a roadmap-friendly platform that reduces redesigns across product generations.
