Molex Mini-Fit Jr 6-Circuit Power Connector (Male)

The Molex 39-01-2060 is a 6-circuit Mini-Fit Jr series male power connector with a 4.2 mm pitch, providing six independent power or signal circuits within a single latched connector body that is physically keyed against adjacent 2-circuit and 4-circuit variants to prevent cross-mating in multi-connector panel harnesses. The 6-position configuration is the most widely used Mini-Fit Jr variant in industrial panel construction, covering the ATX-standard +12 V, +5 V, +3.3 V, GND, and two auxiliary supply rail assignments used in industrial single-board computers, Ethernet switches, and embedded control modules, as well as the three-phase instrument power and earth wiring for industrial control transformers and three-phase monitoring modules. The wire-to-board application dominates in panel OEM fabrication, where the 6-circuit housing is pre-loaded with 18–22 AWG (0.32–0.82 mm²) tinned-copper crimp contacts and routed as a harness to the PCB or backplane header.

The 39-01-2060 housing uses the same UL94 V-0 rated PA66-GF30 material as the 2-circuit variant, with the added structural benefit of a wider footprint that distributes connector insertion and extraction forces across a larger housing body — reducing the risk of circuit board header pad damage during repeated maintenance disconnections in high-duty-cycle environments such as ARAMCO process control panels that undergo bi-annual planned maintenance shutdowns. The dual-row (2×3) contact arrangement on the 4.2 mm pitch gives a total connector footprint of approximately 8.4 mm × 12.6 mm, compact enough to fit in the dense wiring zones of Siemens ET200 I/O modules, Allen-Bradley FLEX I/O, and Yokogawa CENTUM VP field I/O units where connector packing density directly determines the minimum enclosure depth and DIN rail width required.

In the Saudi context, the 6-circuit Mini-Fit Jr male connector is the internal power wiring standard for panel OEMs in Jubail and Riyadh building ARAMCO-specified DCS and SIS cabinets. SABIC's instrumentation panel standardisation documentation for the Jubail and Yanbu complexes specifies Molex Mini-Fit Jr as the approved internal wiring connector family alongside Phoenix Contact SACC and TE MATE-N-LOK for panel-to-field connections. The 9 A per-circuit rating — 54 A aggregate for the 6-circuit connector — gives sufficient headroom for powering the combined 24 V DC, 12 V, and 5 V loads of a fully populated I/O rack in a single harness connector, simplifying the internal wiring layout of ARAMCO SIS marshalling cabinets where wire count management is a key engineering discipline. Panel fabricators building to IEC 61439-2 and ARAMCO GI-0036 rely on the Mini-Fit Jr's audible engagement confirmation and polarised housing to pass workmanship inspection without the need for individual connector continuity testing.

Razz Middle East holds comprehensive Mini-Fit Jr 6-circuit stock including both the 39-01-2060 male housing and the corresponding female 39-01-2060F housing, along with 18–24 AWG 39-00-0060 contacts and the Molex 638111300 crimping tool.
