ABB 3HAC023819-004 UTOW 26-Pin Bayonet Pin Connector, Shell Size 16

ABB 3HAC023819-004 UTOW 26-Pin Bayonet Pin Connector, Shell Size 16

ABB 3HAC023819-004 is the UTOW 26-pole bayonet pin connector, type designation UTOW61626PH, shell size 16, used at the service break points of ABB robot cabling. Fitment is set by the type designation rather than by appearance, so send us the designation on the connector in your robot and we will confirm the match before you order.

Specifications

Industrial Applications

• Power and signal connection points in ABB manipulator and controller cabling that use UTOW-series bayonet connectors.
• Replacement of a damaged, corroded or intermittently contacting connector in an existing robot cable run.
• Field service and preventive maintenance where connectors are inspected and renewed on a schedule.
• Cable-run repairs where a harness section has to be separated and reconnected without re-terminating individual conductors.
• Cells exposed to coolant, humidity or washdown where connector sealing and contact condition are routine inspection items.

Design Purpose

ABB robot cabling routes many power and signal conductors between the controller, the manipulator and the end-effector. Instead of terminating every conductor at a fixed terminal, ABB uses defined circular bayonet connectors — the UTOW series — at service break points, so a cable run can be separated and reconnected quickly during maintenance. The bayonet coupling gives a positive mechanical lock that resists the vibration loosening which a continuously moving robot produces.

That serviceability is also why this part is identified by designation rather than by shape. A UTOW connector is defined by its type designation, shell size, pole count and insert arrangement, and each of those is tied to a specific position in a specific harness. Two connectors can share a shell size and still not be interchangeable. 3HAC023819-004 is therefore a confirmed-fitment spare: it is matched by the type designation called out in the cabling or spare-parts documentation, not selected by appearance.

Common Failure Modes

• Contact corrosion or oxidation from coolant, humidity or washdown.
• Bent or damaged pins from misalignment during mating.
• Intermittent signal or power loss from a loose bayonet lock or partial engagement.
• Seal or insulation degradation shortening service life in oily, dusty or harsh environments.
• Wrong connector fitted — a shell-size, pole-count or insert mismatch that prevents mating or damages the contacts.
• Mechanical stress from cable pull or routing that loads the connector body against the manipulator structure.

Send us the fault code shown on your controller display and we will look at the diagnosis and the matching spare part with you.

Installing and handling it — what to check before and after fitting:

• Isolate and lock out robot power before working on cabling or connectors, and verify zero voltage on the affected circuit.
• Identify the exact connector by type designation (UTOW61626PH), shell size 16 and the 26-pole arrangement from the cabling documentation. ABB UTOW connectors are application- and position-specific.
• Mark and photograph the pin assignments, polarity and keying before separating the halves, so reassembly follows the original wiring.
• Protect both halves from contamination and moisture while disconnected. A contaminated contact face causes intermittent faults that are hard to trace later.
• Align the keyway before mating; do not force the coupling. Forcing a misaligned connector bends pins and damages the insert.
• Verify full insertion, bayonet lock engagement and sealing, then carry out safe isolated checks on the circuit before returning the robot to production.

Why Choose Us
