Description

Spring clamp connections in four pitches

The 240 family provides a single row of spring clamp wire connections with two solder pins per pole. Button-operated models have a raised actuator; W models omit the actuator and have a lower profile. Select the exact pitch, conductor range and electrical rating before laying out the PCB.

Ordering fields

Field	Selection
Model	240 or 240W, with the pitch and series prefix from the model table
Pole count	02P–24P
Colour code	1 grey; 2 blue; 3 black; 4 green; 5 orange; 6 red; 7 transparent; 8 yellow; 9 white
Customer suffix	000A after the colour field in the model drawings
General standard-product field	0A
General screw-head and clamping fields	The common legend defines 0 slot / 1 cross and 0 screw down / 1 screw up; these do not introduce screw connections on the 240 spring models

The common legend's 02–99 pole format covers a wider terminal range; select 2–24 poles for these 240 models.

Model outlines and PCB layouts

N is the number of poles. Dimensions in the next two tables are in millimetres. Each pole has two aligned PCB pins, with 5.00mm between the pin rows.
