  • K8 Cables: pH / ORP

  • S7 / S8 Cables: pH / ORP

  • T82 / D4 Cables: OxyFerm

  • VP6 Cables: pH / ORP, Conducell, OxyFerm VP, and OxyGold

Sensor Electrical Connector Examples

K8

K8 connectors are typically used on traditional pH / ORP sensors which lack temperature compensation. These connectors have a two pole design comprised of the center core and outer metallic threaded connection.

S7 & S8

S7 and S8 connectors are typically found on traditional pH sensors which no temperature compensation. They are the same basic design however S8 connectors have PG13.5 mounting threads, while S7 connectors do not. These connectors are recessed thus care must be taken to avoid moisture getting trapped which could lead to a short circuit.

T82

The T82 connector is sometimes known as a D4 connector. It uses a twist lock design to secure the cable to the sensor. These connectors are less common and only found on the Hamilton OxyFerm FDA Dissolved Oxygen Sensors.

VP (VarioPin)

This is a common connector used throughout the Hamilton sensor product line. VP is abbreviation for “VarioPin”. The VP designation often includes a number referring to the number of exposed poles on connector head. Example VP6 = 6 pole. VP connectors are fully autoclavable with IP68 protection rating.
