Are Hirschmann switches suitable for marine / shipboard applications?
Yes, much of the Hirschmann range is available with the appropriate Germanischer Lloyd (GL) shipbuilding approval, and hence suited to marine applications. Some of the entry level products, such as the Unmanaged SPIDER for example are not available in this form.
This is NOT a standard feature however - the GL approval must be specified for quotation, and ordered with the correct 'H' code in the 'Approvals' field in the part number.
Such applications may also need a conformal coating - this is available with the 'E' or 'F' code in the Temperature Range field, this is also known as the EEC - Extended Environmental Conditions version.
