Protection against immersion in water
09 November 2017
Harting has expanded its Han M range of industrial connector housings with a new series of bulkhead hoods with significantly increased resistance to external influences including dust, dirt and liquids.
The new bulkhead housings meet the requirements of IEC 60529 in protecting interior parts against strong water spray (IP66 degree of protection) and against temporary immersion in water to a depth of one metre (IP67 degree of protection). The special flange of the Han M die-cast aluminium housing prevents water from penetrating into the connector – thus protecting the contact points inside the connector.
The circumferential collar not only seals the housing externally, but also prevents the seal from slipping inwards or outwards. In addition, the seal is more stable on the new housing than its predecessor: it is able to compensate for unevenness, which increases protection against the penetration of water.
The new housings of the Han M series complete HARTING's housing range in sizes 6 B, 10 B, 16 B and 24 B. In addition to offering better protected against external influences, the Han M provides space savings of almost one-third compared to housings with protection class IP68, which are significantly larger.
Applications of Han M housings include industrial sectors such as wind turbines, cranes, external switchgear and railways where operational safety needs to be maintained in extreme environments or under adverse weather conditions.
