XC5B Double-row Sockets, DIN B-type (Standard)

A Wide Variety of DIN Connectors That Conform to UL/CSA Standards.

Fully preserve the characteristics of normal DIN connectors while increasing the number of terminals available.
A wide product range to fit almost any application.
Meeting world market needs with products ranging from one-piece connectors (card edge) to two-piece connectors.
Use the twin-contact system for high reliability.
Lower insertion force as a result of FEM analysis techniques.
Mates with OMRON's XC6-series connectors.
Conform to UL standards (file no. E103202) and CSA standards (file no. LR 62678).

RoHS Compliant

Correct Use

Soldering

Automated Soldering

Use masking tape to mask Right-angle Connectors before automated soldering.

Automated Soldering Conditions (Jet Flow)

1. Soldering temperature: 250±5°C
2. Continuous soldering time: Within 5 s

Basic Mating Dimensions

Mating dimensions for all Connectors should be as shown in the following diagram.

α: 3.55 mm
The distance between the center line of the mounting holes on the mother board and the daughter board. (This center line is shifted 0.3 mm toward row a from row b.)

β: 2.54 mm
The distance between the mounting holes on the daughter board and row a.

γ: 5.3 mm
The distance between the edge of the daughter board and row a.

δ: 12.4 to 14.2 mm
To ensure reliability, be sure to keep the Connectors within these dimensions when mounting.

The allowable margins for mating the Connectors are shown below.
