Selection & installation notes
- Choose by both conductor size and insulation diameter. Color is a selection aid; verify pin count, pinout and mating compatibility.
- The ESTB accessory chart gives different yellow/blue insulation ranges (yellow 1.0–1.4 mm; blue 1.4–1.6 mm). Confirm the exact connector revision before ordering.
- Insert each wire fully and inspect through the cover. Do not exceed the stated current-dependent ambient limit.
- Outline dimensions, mass, soldering temperature/time and mating-cycle life are not provided; request the model-specific drawing and assembly instructions.
- Disconnect power before insertion/removal, grip the connector body and provide strain relief in vibrating equipment.
