Description

Model and pitch selection

The 66 series uses a single row of M4 screw connections with 2-24 positions. Select 66S/A for mounting ears, 66S/B for a compact body with straight pins, or 66R/B for side-projecting pins. Match the mechanical pitch to the complete model: 66S/A uses 11mm, while the two /B models use 11.11mm. All three are shown uncovered.

Ordering

Select the complete model, position count and color. The /B order formats are ULO-TB39-66S/B-XXP-Y100A and ULO-TB39-66R/B-XXP-Y100A. XX is 02-24 positions; Y is the color code. The 100A ending selects a cross-head screw, screw-down clamping and the standard 0A product configuration.
