|---|---|---|---|---|---|---|---|
| Explanation: |
Brand ULO - ULO |
Model MJ498 - Compact circular connector |
Contacts 2 - 2 contacts |
Colour W - White |
Plating 6 - Tin |
ULO-MJ498 provides circular cable and panel components with two to nine contacts. The cable component includes a rear clamp and knurled coupling; the panel component uses a threaded fitting and hexagonal retaining nut. Black and white insulators are selectable.
| Characteristic | Value |
|---|---|
| Contact populations | 2, 3, 4, 5, 6, 7, 8 or 9 |
| Maximum current rating | 5A |
| Contact resistance | ≤50mΩ |
| Insulation resistance | 1000MΩ |
| Dielectric withstand test | 500VAC for 1 minute |
| Insulator | Thermoplastic, material group I |
| Material flammability | UL94V-0 |
| Contacts | Copper alloy, tin plated |
Working voltage, operating temperature, ingress-protection rating and allowable wire size are unspecified. The dielectric withstand test does not establish a working-voltage rating.
The fields after MJ498 select contact count, insulator colour and plating. Use the numbered contact face for the selected population when identifying terminals.
| Field | Code | Selection |
|---|---|---|
| Contact count | 2 / 3 / 4 / 5 / 6 / 7 / 8 / 9 | Corresponding number of contacts |
| Insulator colour | W / B | White / black |
| Contact plating | 6 | Tin |
The drawing shows the connector assembly and eight contact layouts. Its 5.95mm dimension is an illustrated tail-spacing reference; individual circular inserts have different arrangements. The Ø2.5mm contact reference belongs to the two-contact face shown beside the nut outline.
| Drawing reference | Dimension |
|---|---|
| Assembly length | 46.6mm reference |
| Rear clamp-section width | 13.9mm |
| Intermediate body width | 12.9mm |
| Hexagonal nut span | 19mm |
| Illustrated tail-spacing reference | 5.95mm |
| Two-contact face contact reference | Ø2.5mm |
The panel thread is shown without a nominal thread designation or pitch. Contact numbering identifies positions; an application wiring assignment is unspecified.
