CBZL5FN Push-Pull Connector for Dredging Pump Monitoring Systems 2026: 105F 16-Contact Panel Socket

The CBZL5FN-SFP816-S650 is a CBZL5FN push-pull connector for dredging pump monitoring systems — a 105F multipole panel-mounted hermetic receptacle with sixteen contacts in mixed sizes (four larger contacts rated 14 A and twelve smaller contacts rated 1 A), rear-panel mounting, a push-pull self-locking mechanism, solder termination, IP68 protection when mated on the 105F platform, operation from -55 °C to +145 °C, vibration resistance of 10~20,000 Hz at 147 m/s² with ≤1 µm instantaneous break, impact resistance of 490 m/s², a chrome-plated brass shell with gold-plated contacts and a PPS insert, and more than 3,000 mating cycles. Every specification in this guide is backed by the submersible equipment interconnect engineering of Spring Technology.

Pain point: Getting auxiliary supply plus a dozen sensor signals out of a sealed pump enclosure — where the pump sits in sand, sludge and slurry, the junction box must stay dry, and servicing means disconnecting one cable assembly instead of unwiring a terminal block?

Core answer: The CBZL5FN-SFP816-S650 is a multipole panel-mounted receptacle whose sixteen-contact configuration provides a compact connection interface for equipment requiring a combination of electrical power and low-voltage signal connections. One potential application is a submersible dredging pump control and monitoring system — pumps used in harbour maintenance, river dredging, mining operations and industrial sediment removal, where the system may require connections for auxiliary electrical circuits, temperature sensors, pressure sensors, leakage detection and other monitoring signals. The connector can be considered for integration into a sealed electrical enclosure or auxiliary connection compartment, with its mixed-contact configuration allowing designers to organise different circuits within one interface.

Note: this connector is intended as an equipment-integration solution for auxiliary power and monitoring circuits — the main motor power connection should be designed separately according to motor voltage, current, cable requirements and applicable electrical safety standards. Protection must be checked for the exact ordered part number and its mated or unmated condition; the enclosure design, cable assembly and installation method also affect the protection of the complete system.

2. Key Advantages of the CBZL5FN-SFP816-S650

A dredging pump’s junction box has to survive mud and still be serviceable. The design advantages below explain why this CBZL5FN push-pull connector for dredging pump monitoring systems suits sealed pump enclosures:

2.1 Sixteen Contacts for Combined Power and Signal Connections

  • The CBZL5FN-SFP816-S650 uses a 16-contact configuration with different contact sizes. This mixed arrangement gives designers flexibility when assigning auxiliary power circuits and monitoring signals — instead of several independent interfaces, multiple electrical connections are organised through one connector assembly, simplifying cable routing between the pump-side sensor harness and the external monitoring equipment.

2.2 Different Contact Sizes for Flexible Circuit Assignment

  • The insert combines larger and smaller contacts: in the complete catalog configuration four larger contacts are specified at 14 A per contact, while twelve smaller contacts are specified at 1 A per contact. This suits systems requiring separate auxiliary supply and low-voltage sensor circuits — while actual contact assignment, current derating and circuit protection must be verified against the complete connector datasheet.

2.3 Rear Panel Mounting for Enclosure Integration

  • The receptacle belongs to the rear-mounted panel receptacle design, allowing integration into an electrical enclosure, junction box or equipment connection compartment. Internal wiring is arranged behind the panel while the external cable assembly connects through the receptacle interface — making equipment assembly and cable maintenance more organised for industrial pump systems.

2.4 Sealed Configuration Options for Demanding Environments

  • The 105F hermetic panel receptacle family offers sealed and vacuum-tight configurations, and the platform specification for the mated condition is IP68. This is relevant when designing connection interfaces for equipment exposed to moisture, mud or outdoor operating conditions — and any unmated-state sealing claim must be confirmed for the exact ordered part number rather than assumed.

2.5 Convenient Maintenance and Cable Replacement

  • Dredging equipment often operates for extended periods and may require inspection of its sensors, cables and electrical compartments. A dedicated multipole connector interface lets technicians disconnect an external cable assembly without individually removing every conductor from the internal terminal block — simplifying maintenance, reducing wiring work and making replacement of external assemblies more convenient.

3. Why Choose the CBZL5FN-SFP816-S650?

Submersible dredging pump monitoring systems need reliable connections for auxiliary electrical circuits and multiple sensor signals, and their connector interfaces must also suit the mechanical structure and environmental protection requirements of the equipment. This CBZL5FN push-pull connector for dredging pump monitoring systems offers a 16-contact mixed configuration and a rear-mounted panel receptacle design — characteristics that make it a potential solution for organising auxiliary power and monitoring signal connections in industrial pump control enclosures, with final selection based on the complete part number, mating connector, contact assignment, operating current and required sealing performance.

5. Frequently Asked Questions (FAQ)

Q1: How many contacts does the CBZL5FN-SFP816-S650 have?

**Answer:** It has a 16-contact configuration with different contact sizes — four larger contacts at 14 A and twelve smaller contacts at 1 A in the complete catalog configuration.

**Answer:** It can be considered for equipment requiring combined auxiliary power and low-voltage signal connections, such as industrial pump monitoring enclosures and control systems. Discover reliable options from a certified vendor like [Spring Technology](https://www.spring-connectors.com/).

**Answer:** A suitable sealed configuration may be considered for equipment exposed to water — however, the exact part number and its mated or unmated sealing performance must be verified before underwater installation.

**Answer:** Its mixed-contact configuration allows different circuits to be assigned to different contact sizes; the actual current and signal assignments must follow the technical specifications of the exact configuration.

**Answer:** It should not automatically be selected for the main motor supply — motor voltage, operating current, starting current, contact ratings and applicable safety requirements must be evaluated separately; this application focuses on auxiliary power and monitoring connections.

**Answer:** The 105F platform specification is IP68 when mated; sealed variants exist within the family, but the exact rating for a given ordering code and its mated or unmated condition must be confirmed on the product drawing.

**Answer:** It is a rear-mounted panel receptacle with solder termination and push-pull fastening, so internal wiring stays behind the panel while the external cable assembly plugs in from outside.
