SP Series IP68 Waterproof Connector for Rice Transplanter Sensors

M8 Waterproof Connector Types and Specifications

Selecting a Waterproof Connector for a Rice Transplanter Water Level Sensor

For a water level sensor on a rice transplanter that is frequently immersed in muddy water up to 10 cm deep, the primary selection criteria are the ingress protection (IP) rating, corrosion resistance, and mechanical durability of the connector. The SP series 8-pin waterproof connector is a suitable choice for this application.

Key Selection Criteria for Submerged Sensor Connectors

• Ingress Protection (IP) Rating: The connector must be rated for continuous immersion. An IP68 rating ensures protection against the effects of immersion in water beyond 1 meter, providing a significant safety margin over the 10 cm operating depth.
• Environmental Resistance: The connector housing and sealing must withstand exposure to muddy water, fertilizers, and other agricultural chemicals. A metal shell with double O-rings provides robust sealing, while a salt spray test rating of ≥1000 hours indicates strong corrosion resistance.
• Signal Integrity: For accurate water level measurement, the connector must maintain stable electrical contact. In this configuration, 4 pins are dedicated to transmitting the water level signal, supporting an accuracy of ±1 cm.
• Mechanical Durability: The connector should endure repeated mating and unmating cycles during maintenance. A plug-in life of ≥3000 cycles meets the typical annual 200-hour operation demand of agricultural machinery.

SP Series Connector Specifications for This Application

The SP series 8-pin connector is designed for in-line power and signal connections in demanding environments. Its IP68 rating and corrosion-resistant construction make it well-suited for the paddy field operation scenario of a rice transplanter. For applications requiring a different pin count or specific cable assembly, review the SP Series waterproof wire connector options.

Application Boundaries and Installation Notes

While the IP68 rating covers immersion, it is important to note that the connector's performance is verified when properly mated. The connector should be fully seated and the locking mechanism engaged to maintain the seal.
