Quotation confirmation

Details required before production

Send the selected model and matching pipe information so the supplied saddle, paddle and signaling configuration follow the approved quotation.

Pipe selectionProvide nominal size, actual pipe outside diameter and available installation space.
Electrical requirementReference contact capacity: DC 24 V, 0.5 A. Confirm the rating, contact form and load type for the selected switch with the quotation. This is a contact rating, not a power-supply requirement.
Alarm requirementConfirm the required alarm-flow and reset criteria for the project.
Order informationProvide quantity, destination, packing and required documents.
