SPJ

Supported Applications

The Omega SPJ Series consists of universal snap-in panel jack connectors designed for standard and miniature male thermocouple connectors. These self-securing devices feature a design that eliminates the need for separate mounting hardware by incorporating retaining spring clips directly into the body. The series supports ANSI-designated calibrations including K, T, J, E, R/S, U, and N. Type U (uncompensated) models are specified for use with Type B thermocouples, 2-wire RTDs, or thermistors.

Operating Conditions & Performance

The SPJ Series connectors are constructed from glass-filled nylon rated for an ambient temperature range of -29 to 220°C (-20 to 425°F). The electrical connection accepts solid or stranded wire up to size 14 AWG. Each unit includes combination Phillips/slot screws and a wire divider.

Physical dimensions are defined as follows:

• Overall Height: 44.45 mm (1.75 in)
• Overall Width: 24.6 mm (0.97 in)
• Panel Cutout: 16.12 mm (0.635 in) x 30.4 mm (1.195 in)

Configuration Options

The series offers configurable options for thermocouple type, connector gender, and identification accessories.

• Thermocouple Calibrations: Available with compensating alloys matching Type K (Yellow), T (Blue), J (Black), E (Purple), R/S (Green), U (White), and N (Orange). Tungsten alloys C, D, and G are available only in the old, non-universal style.
• Connector Gender: Models are offered as female connectors (suffix "-F") or male pins. To order a male version, change the suffix from "F" to "M" (e.g., SPJ-K-M).
• Identification & Protection: Optional dust caps (SPJ-CAP) and ID number labels are available in ranges 1-6L through 1-100L. Custom marking is offered by consulting the Sales Department.

Key Product Differences

The SPJ Series distinguishes itself from previous generations via a universal snap-in design that accepts both standard and miniature male connectors without additional tools. A small tab and notch on the body facilitate straight, even rows during installation. For large volume users requiring removal of installed units, the SIRT-1 Removal Tool is available.

Model numbering follows the format SPJ-[Alloy Code]-[Gender], where "F" denotes female and "M" denotes male. The series replaces the previous UPJ style; legacy orders can be converted by replacing the initial "S" with a "U" in the model number (e.g., changing SPJ to UPJ).
