Amphenol C16

Amphenol eco|mate® C16 Family

The circular connectors of the eco|mate C16 family provide a range of different contact arrangements on two shell sizes. The portfolio includes connection solutions for multi-phase power transmission as well as a selection of combined hybrid interfaces. All versions come including a protective earth (PE) contact.

Characteristics of the eco|mate C16 series are the use of robust plastic, a reliable bayonet locking and mechanical codability. Especially the cost-efficient assembly is an advantage from which many of our customers are already benefiting.

The product family can be divided into two sub-series:

  • C16-3: Power and hybrid solutions: 10 contact arrangements on 2 shell sizes; up to 36A and 900V; crimp and screw contacts with wire cross-section 0.09-6mm²; protection class IP65
  • C16-L: Contact arrangement 4+PE especially for three-phase PV inverters; up to 50A at 600V; screw contacts with wire cross-section 2.5-8.3mm²; protection class IP65

Circular connectors of the eco|mate C16 family are used e.g. in the fields of industrial automation, mechanical engineering; renewable energies, control systems and lighting technology.

MIL-DTL-26482 (MS, 62IN/GB, PT..)

Miniature cylindrical connectors MIL-C-26482 offer twice the number of contacts in just half the size of a standard connector MIL-C-5015. These miniature connectors, are available in several series, each with varying design characteristics and customer options to meet cost considerations and provide maximum design flexibility. There are two styles within the family that are MS approved and qualified to MIL-DTL-26482, Series 1, and in addition there are several proprietary styles.

Common features of all styles:

  • All are for general duty applications and environmental sealing is achieved with the grommet and clamp design.
  • Operating temperature is from –55°C to +125°; Operating voltage to 1000 VAC (RMS) at sea level.
  • Pin and socket contacts are machined from low loss copper alloy and gold plated to eliminate contact corrosion and provide an indefinite shelf life.
  • All have resilient inserts which provide high dielectric strength and moisture barrier.
  • A variety of shell finishes (including non-cadmium) and a variety of backend accessories are available within the styles.
MIL-DTL-38999 (LJT/HE308, TV..)

Subminiature cylindrical connectors were developed to meet the needs of the aerospace industries and provided the impetus for development of the MIL-C-38999 specifications, which recently were superseded by MIL-DTL-38999. Circular connectors MIL-C-38999 are available in different materials such as aluminium, stainless steel, marine bronze, composite and with various surfaces such as zinc-tin, green cadmium, black-zinc-nickel and nickel-plated.
