Phoenix Contact 1674134 Heavy Duty Connector Base - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1674134 is a Heavy Duty Connector base unit designed for box mount, side entry applications with PG21 thread size in the HEAVYCON® B series. This connector provides IP65 ingress protection (dust tight, water resistant) and operates across a temperature range of -40°C to 125°C. The part is currently obsolete, making identification of suitable substitute components essential for system maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1674134 is determined by strict alignment of the following critical parameters:

• Connector Type & Style: Base - Box Mount, Side Entry configuration
• Size Designation: B24 form factor
• Thread Interface: PG21 thread size
• Lock Mechanism: Locking Clip (1) on Base Bottom
• Operating Temperature Range: -40°C to 125°C
• Housing Material: Aluminum, Die Cast construction
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The substitute part 1412879 maintains all these core parameters while providing enhanced ingress protection (IP66/IP67/IP69K versus IP65) and additional features including salt water resistance and feed-through capability. Both parts share identical electrical and mechanical interfaces, enabling direct functional substitution in applications where the enhanced environmental protection of the newer series is acceptable or beneficial.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1412879 serves as the direct functional substitute for the obsolete 1674134. Selection between these parts should be based on the following criteria:

Use 1674134 (Original): Only in legacy system maintenance where exact series continuity with existing HEAVYCON® B infrastructure is mandated and IP65 protection is sufficient for the application environment.

Use 1412879 (Substitute): For all new designs, system upgrades, and replacement scenarios. This part is active in production, carries current RoHS3 compliance certification, and provides enhanced ingress protection (IP66/IP67/IP69K) suitable for demanding industrial environments including salt water exposure. The HEAVYCON® EVO series represents the current generation technology with improved environmental sealing and feed-through capability.

Both parts maintain identical mechanical interfaces (B24 size, PG21 thread, side entry configuration, locking clip mechanism) and identical operating temperature specifications, ensuring direct interchangeability at the connector interface level.

Frequently Asked Questions (FAQ)

Q: Can the 1412879 directly replace the 1674134 in existing installations?

A: Yes. Both connectors share identical mechanical interfaces (B24 size, PG21 thread, side entry configuration) and locking mechanisms. The 1412879 provides enhanced ingress protection without requiring any mechanical or electrical interface modifications.

Q: What is the primary difference between these two parts?

A: The 1412879 belongs to the HEAVYCON® EVO series and provides IP66/IP67/IP69K ingress protection with salt water resistance, compared to the IP65 rating of the 1674134 HEAVYCON® B series. Both maintain identical operating temperature ranges (-40°C to 125°C) and housing materials.

Q: Why is the 1674134 listed as obsolete?

A: The 1674134 has been superseded by the 1412879 in the Phoenix Contact product line. The newer HEAVYCON® EVO series offers improved environmental protection and current compliance certifications.

Q: Are there any dimensional differences between these connectors?

A: The height dimension differs slightly: 1674134 measures 2.638" H (67.00mm), while 1412879 measures 2.677" H (68.00mm). Length and width dimensions are identical at 5.669" L x 2.244" W (144.00mm x 57.00mm).

Q: What compliance certifications apply to each part?

A: The 1674134 carries RoHS Compliant certification. The 1412879 carries ROHS3 Compliant certification and is REACH Unaffected, representing current regulatory compliance standards.

Q: Can these connectors be used in salt water environments?

A: The 1412879 is specifically rated for salt water resistance with IP66/IP67/IP69K protection. The 1674134 with IP65 protection is suitable for dust and water resistance but is not specified for salt water applications.
