Power for mobile applications
Robust plug connectors are designed for demanding applications with high power levels.
P
lug connectors for outdoor power supply systems must ensure a dependable transmission of electric current under rugged conditions. Mobile applications call for robust design and a large number
of mating cycles. Te Multi-Contact plug connectors of series 16BV
and 21BV are designed for demanding applications with high power levels. Depending on their version, these robust single-pole round plug connectors are in conformity with protection classes IP65, IP67 and IP68. Tey are touch-protected in accordance with IP2X when unmated. A safe, dependable contact is ensured by a bayonet locking system and colour coding. An optional microswitch on the switchboard signals when a connection has been made and can be integrated into a machine enabling safety circuit. Te MC Multilams ensure high contact quality with constantly low transmission resistances throughout the life of the connectors, and permit a large number of mating cycles.

Electromagnetic shielding 16BV plug connectors for currents up to 530A have given excellent service in emergency power supply systems for many years. Tey are used, for example, in mobile emergency power supplies and for emergency infeed into transformer stations. Typical areas of application also include test facilities and switchgear. With protection class IP65, the 16BV is suitable for outdoor use.

Te shielded 16BV-GS is designed to minimise electromagnetic emissions. Multi-Contact developed this connector as a customer-specific solution for power supply systems with a frequency converter for applications such as powering 3-phase motors. Fields of application include, for example, deep-drilling plant for geothermal energy and power chains of crane installations.
An additional shielding contact ensures continuous shielding and gives reliable protection from electromagnetic emissions. Te 16BV-GS is designed for cable cross-sections from 120 to 240mm². Te receptacle is simple to install in the panel, and can be integrated from either the front or the back. With its captive protective caps and robust design, the 16BV- GS is suited for use in harsh conditions. Te bayonet locking system is a unique feature in shielded plug connectors of this size.
