Terminal block module CAYMON CASY138/B — 2x 3-pin screw/plug connector module

CAYMON CASY138/B — 2x 3-pin screw/plug connector module is a compact terminal block module that provides two independent 3-contact connection points for signal or low-voltage power wiring. The module accepts screw or plug termination, allowing secure connections with the option to detach or reconfigure wiring quickly. Its form factor is suitable for control panels, instrument racks, prototype assemblies and device-to-device interconnections where a small, modular terminal interface is required.

Advantages

The module offers a compact, modular design that simplifies wiring and reduces panel space. Screw and plug termination options deliver reliable mechanical and electrical contact while enabling fast replacement or reconfiguration of connected cables. Construction materials and contact design ensure stable low-voltage signal transfer and reduce risk of accidental disconnection during maintenance. The two separate 3-pin points provide flexibility for grouping signals or power lines without using multiple separate connectors.

Suitable for

• Control panels and automation cabinets
• Prototyping and development boards
• Device interconnections in rack systems
• Low-voltage signal and power wiring
• Maintenance environments requiring quick cable changes

Key specifications

• Connector configuration: two independent 3-contact terminals
• Termination types: screw and plug compatible
• Application: signal and low-voltage power connections
• Mounting: panel- or rail-compatible compact module form factor
• Contact arrangement: individual pins with secure fastening

How to use

Install the module into the intended panel or rail space according to the mounting provisions of the enclosure. Strip conductors to the recommended length, insert each conductor into the appropriate terminal contact and tighten screws to the specified torque to ensure a secure electrical connection. For plug termination, attach the mating plug assembly before routing cables; verify proper engagement and retention. Label terminals as necessary to maintain clear wiring identification during installation and future maintenance.

Usage recommendations

Use appropriate wire sizes and observe the device or system’s rated voltage and current limits. Tighten screw terminations to the recommended torque to avoid loose connections or conductor damage. When reconfiguring wiring, power down circuits before disconnecting plugs or loosening screws. Regularly inspect connections for corrosion or loosening in environments with vibration or humidity.
