The OMEGA PCC-SMP-V-K-5 is a vertical-mount, solderable PCB thermocouple connector designed for K-type thermocouple probes. Manufactured by OMEGA Engineering, this miniature connector provides a direct mechanical and electrical interface between thermocouple sensors and printed circuit boards in industrial temperature monitoring systems. The vertical orientation (PCC-SMP-V) saves board space compared with horizontal variants, making it suitable for compact handheld instruments and densely populated control boards. The connector shell is molded from glass-filled nylon, and the contact pins use beryllium copper alloy for the uncompensated (U) version, which offers higher mechanical strength than standard copper after repeated mating cycles. With an operating temperature range of -29°C to 180°C (-20°F to 356°F), the PCC-SMP-V-K-5 supports continuous signal transmission in factory automation, laboratory calibration, and OEM temperature measurement equipment.
The PCC-SMP-V-K-5 uses beryllium copper alloy contacts in its uncompensated configuration. This material delivers greater tensile strength and spring retention than pure copper, which helps maintain consistent contact resistance after repeated plug-and-unplug operations. For compensated types (J, K, T, N, E), the pin alloy is matched to the corresponding thermocouple conductor material to minimize parasitic electromotive force at the junction.
The connector maintains structural and electrical performance across a -29°C to 180°C (-20°F to 356°F) range. The glass-filled nylon shell resists thermal deformation within this span, allowing the part to be used in both cold-chain monitoring equipment and high-temperature industrial process lines without requiring a separate adapter.
The PCC-SMP-V-K-5 is designed for through-hole soldering directly to a PCB, eliminating the need for intermediate wiring harnesses. The vertical mounting orientation places the connector body perpendicular to the board surface, reducing the footprint required on the top layer. This configuration is commonly selected for handheld thermometers, data loggers, and portable calibration instruments where board space is constrained.

The PCC-SMP-V-K-5 is deployed across several industrial segments. In OEM electronic equipment manufacturing, it is integrated into mass-produced temperature measurement instruments to standardize the thermocouple interface and simplify assembly. In handheld meter design, the vertical form factor and direct soldering enable compact enclosure layouts. For cold junction compensation (CJC) circuits, the optional TO-92 transistor retainer clip allows a temperature-sensing transistor to be mounted at the connector entrance, providing a reference junction measurement close to the thermocouple contact point. The connector is also used in industrial automation temperature monitoring units, laboratory prototyping boards, and data acquisition modules where a standardized, repeatable thermocouple interface is required.
The PCC-SMP-V-K-5 is calibrated for K-type thermocouples. The broader PCC-SMP connector series also supports J, T, N, and E types with alloy-matched pins, and a Type U version with beryllium copper contacts is available for uncompensated applications.
The PCC-SMP-V-K-5 operates from -29°C to 180°C (-20°F to 356°F). The glass-filled nylon shell and alloy contacts are rated for continuous use within this range.
The PCC-SMP series offers an optional TO-92 transistor retainer clip that mounts a temperature-sensing transistor at the connector entrance, enabling cold junction temperature measurement for compensation circuits.
The "-V" suffix indicates a vertical mounting orientation, meaning the connector body stands perpendicular to the PCB surface. The horizontal variant is designated PCC-SMP (without the -V suffix).
