Y2M21 Russian Standard Circular Connector 2-65 Pin Bayonet Lock

PC Series Circular Connector Types and Specifications

Y2M21 Russian Standard Circular Connector Overview

The Y2M21 Russian Standard Circular Connector is a rugged industrial interconnect designed for reliable power and signal transmission in automation equipment, machinery systems, and electrical control devices. Built to the traditional Russian connector standard, the Y2M21 series combines a compact circular structure with strong mechanical protection and dependable electrical performance.

Its quick bayonet locking system and screw connection design ensure stable, secure installation, while the rugged aluminum housing and reliable contact structure support long-term performance in demanding industrial environments.

Key Selection Criteria for the Y2M21 Connector

When evaluating the Y2M21 for your application, consider these primary decision points:

• Core Count and Gender: Available in 2 to 65 pins, with male and female configurations to match your wiring scheme.
• Locking System: The quick bayonet lock provides fast, secure mating, which is critical for applications requiring frequent connect and disconnect cycles.
• Environmental Resistance: The aluminum housing and PBT insulator are selected for mechanical strength and stable insulation over a wide temperature range.
• Termination Method: Screw connection offers a straightforward, reliable method for field wiring and equipment assembly.

Durable Metal Housing for Industrial Protection

The Y2M21 connector features a strong aluminum housing designed to protect the internal contacts from external damage. In industrial environments, connectors are often exposed to vibration, mechanical impact, dust, and temperature changes.

Compared with plastic connectors, metal housings offer superior strength and durability. The Y2M21 connector benefits from this design in several ways:

• High mechanical strength
• Strong resistance to impact and vibration
• Improved heat dissipation
• Enhanced protection for internal contacts

The metal shell also helps extend the service life of the connector by reducing wear and improving structural stability. This makes the Y2M21 connector suitable for long-term use in heavy-duty equipment and industrial systems.

Quick Bayonet Lock for Fast and Secure Connection

One of the key features of the Y2M21 connector is its quick bayonet locking structure. This design allows the connector to engage quickly and lock securely during installation.

Bayonet lock connectors are popular in industrial applications because they simplify installation while maintaining a strong connection. Once the connector is inserted into position, the locking mechanism holds it firmly in place.

Benefits of the quick bayonet lock design include:

• Quick and convenient installation
• Stable connection during operation
• Reduced risk of accidental disconnection
• Improved efficiency during assembly

This feature is particularly useful for equipment that requires frequent maintenance or component replacement.

Screw Connection for Strong Mechanical Fixing

In addition to the bayonet lock, the Y2M21 connector uses a screw connection method for cable installation. Screw termination is widely used in industrial connectors because it provides a secure and reliable way to connect wires.

The screw connection ensures strong mechanical fixation between the cable and the connector. This design helps maintain stable electrical contact even in environments with vibration or movement.

Advantages of screw connection include:

• Easy installation and maintenance
• Reliable wire fixation
• Good electrical conductivity
• Suitable for field wiring and equipment assembly

Because of its simple and practical structure, screw connection is commonly used in industrial equipment and control systems.

Application Scope and Boundaries

The Y2M21 connector is designed for industrial electrical systems where a rugged, reliable connection is required. Its construction makes it a strong candidate for the following:

• Automation equipment and control panels
• Industrial machinery and heavy-duty equipment
• Power and signal transmission in factory settings

However, it is important to verify the specific environmental and electrical requirements of your application. The connector's suitability for outdoor use, exposure to chemicals, or high-vibration environments should be confirmed against the detailed specifications and your operating conditions.

Parameter Interpretation and Installation Guidance

For proper selection and installation, the Y2M21 connector should be evaluated against your system's requirements. The core count, gender, and termination method must match your cable and mating connector. The operating temperature range and housing material are key factors for environmental fit.

During installation, ensure the cable is correctly prepared and the conductors are securely fixed in the screw terminals. Proper mating of the bayonet lock is essential to achieve the designed mechanical and electrical connection.

Inquiry Checklist for Accurate Quotation

To receive an accurate quotation and ensure the correct connector configuration, please provide the following information:

• Required number of cores and gender (male/female)
