IN Brief:
- Farnell is adding Amphenol NEXUS products across its EMEA distribution operation.
- The portfolio includes M55116, TAC, Ranger, waterproof breakaway and audio connector families.
- Products target military, aviation, telecommunications, medical, marine and industrial applications.
Farnell has added Amphenol NEXUS Technologies to its EMEA supplier portfolio, expanding its range of connectors and switches for communications and control equipment exposed to demanding mechanical and environmental conditions.
The agreement covers audio connectors, waterproof breakaway products, TAC and Ranger connectors, M55116 and related military type connectors, microphone and telephone plugs and jacks, and momentary push button switches. Products are available through Farnell in EMEA, Newark in North America and element14 in APAC.
Connectors in these applications have to preserve signal continuity while their housings, contacts and cable interfaces are exposed to vibration, repeated mating, contamination, moisture and physical handling. Electrical ratings alone do not establish suitability because sealing, contact geometry, coupling method and mechanical life can determine whether the connection remains stable in service.
Amphenol NEXUS has built much of the range around military audio and communications hardware. Standard M55116 products use stainless steel shells, bayonet coupling and gold plated brass contacts with silver plated beryllium copper spring elements. Typical six contact versions are rated at 0.5 A and 60 V, with an operating range from -55°C to 85°C.
The TAC family reduces the size of that interface for equipment where enclosure volume and cable weight are constrained. Amphenol describes the miniature TAC plugs and receptacles as approximately half the size of standard M55116 connectors while retaining many of the electrical and mechanical characteristics used in portable communications equipment.
A typical six contact TAC plug retains stainless steel construction, bayonet coupling, a 0.5 A current rating and a 60 V maximum voltage. Its spring contact arrangement produces a wiping action during mating, so the contact surfaces move against each other as the connector is engaged rather than meeting at a fixed point.
The Ranger family provides higher contact density and a wider range of interface combinations. Selected variants are specified for 5,000 mating cycles and operation from -51°C to 125°C, with environmental protection options including IP6K8/IP6K9K or IP68/IP6K9K when mated. Configurations can combine power contacts with data interfaces including USB, depending on the application.
Waterproof breakaway products address systems where a cable may need to disconnect without an operator first releasing a threaded or bayonet coupling. The connection still has to remain sealed and mechanically stable during normal use, so the release force, cable construction and environmental performance become part of the equipment design rather than an accessory choice.
Part selection can become difficult because a single connector family may include several shell styles, contact arrangements, termination methods, keying options and sealing levels. Two variants that appear equivalent electrically can be incompatible with the enclosure, cable assembly or qualification requirements once their mechanical details are compared.
Broadline distribution gives design teams access to those variants alongside the rest of the bill of materials, which is useful when prototypes or low volume systems need several connector configurations before the enclosure and cable design are fixed. The value depends on access to the correct drawings, part numbers and stock rather than the number of catalogue entries alone.
Rugged fibre interfaces face many of the same mechanical constraints. FC Lane recently added Cinch Fibreco JCON Junior adapters for equipment that needs a standard optical connection behind a protected bulkhead, again placing enclosure mechanics and serviceability alongside the electrical or optical interface.
Amphenol NEXUS has operated since 1961 and has been part of Amphenol Corporation since 2008. Its products are used across military and commercial communications, aviation, telecommunications, medical equipment, simulation, motorsport, marine systems and agricultural machinery.
The Farnell agreement is effective now, with the practical engineering choice still made at variant level. Contact count, shell arrangement, termination, coupling and sealing have to match the equipment as closely as the nominal signal or power requirement, particularly where the connector will be handled repeatedly outside a controlled indoor environment.
