Durable For Heavy Industry
The Deutsch series of Caterpillar electrical connectors have been specially developed to meet the requirements of heavy industries where failure is not an option. These durable connectors offer high performance and field-proven reliability in the harshest environments.
Electrical connectors like those used in Caterpillar mining machinery must be able to withstand rigorous conditions and all weather environments. Even minor faults in electric systems can lead to equipment failure which can bring entire operations to a halt. Expenses quickly add up through diagnostics, repairs and lost productivity which makes it essential to choose only the best in sealed electrical connectors.
Connector-Tech ALS is a proud supplier of Caterpillar electrical connectors from Deutsch which have become the trusted choice to maintain the connection of essential equipment. We offer prompt delivery Australia-wide and our expert team can help you find the part you need.Deutsch DT Caterpillar-Spec Information
The Deutsch DT Series features the Caterpillar Specification (CAT-Spec) connectors that are easily identified by their black colour.
These connectors have improved seal retention on the plug and a cap on the rear of the housing to retain each connector's rear wire seal. They are used as OEM connectors on Caterpillar machinery, many Harley-Davidson motorcycles and other agricultural, commercial and automotive applications.
Applications for the Caterpillar versions of the Deutsch DT series include automotive (Harley-Davidson, V-Twin or Two-Stroke motorcycles, off-road, ATV), Marine, Harsh Environment & Heavy Equipment.

When ordering a connector it is not always as simple matter of determining between 'male' and 'female' because this can refer to both the housing gender and the contact gender. Many manufacturers offer a given housing gender with both pin and socket. A common example of such confusion occurs in the Deutsch Industrial DT range, where the plug (or male connector) actually contains socket (or female) contacts. For this reason please specify both the contact and housing gender at the time of order.
The IP Rating of a connector or accessory relates to the degree of ingress protection provided by that component. The first digit of the code relates to the degree of protection against access to hazardous parts (conductors etc) and against solid foreign objects. The second digit refers to the degree of protection against the ingress of water. For two examples of this system, consider the most commonly seen IP ratings in our products: IP44 and IP67. IP44 4: Protection from solid objects ≤1mm | 4: Protection against splashing water IP67 6: Protection from dust-sized objects | 7: Protection against immersion in water at depth of 1m for 30mins A complete guide to all IP Ratings is available here.
These terms are used by Phase 3 and ITT Veam on their high-current connectors.The source is considered the half of the connection from which the power is sourced; or the half supplying the electrical power. In an emergency power application, the generator is the source and would be fitted with Panel Source (panel-mount) connectors, a Panel Source Powersafe Box, or Line Source (inline) connectors on pigtails. The drain is the half of the connection which drains the power from the source. In the same emergency power application described above, the network receiving the emergency power supply is the drain and would be fitted with Line Drain connectors, Panel Drain connectors or a Panel Drain Powersafe Box.
We commonly deal with both American Wire Gauge (AWG) and square millimetre (mm2) dimensions as the units used by manufacturers can vary. To convert between measurements please refer this conversion chart.
