Frequently Asked Questions

What contact combinations are available for these auxiliary contact modules?

Modules are available in 2-contact and 4-contact options, offering various NO (normally open) and NC (normally closed) compositions including 1NO+1NC, 2NO, 2NC, 2NO+2NC, 1NO+3NC, 4NO, 4NC, and 3NO+1NC.

How are the auxiliary contact blocks installed onto an AC contactor?

They are built with a modular structure that allows quick clamping or snap-on installation and removal without requiring extra tools. Options include both front mounting and side mounting depending on the contactor model.

What materials ensure the safety and longevity of the contacts?

The contacts utilize high-conductivity alloy for low electrical resistance and stable operation. The outer casing is manufactured from a flame-retardant, high-temperature resistant, and anti-aging insulated housing.

What typical applications do these auxiliary contact units serve?

They are extensively used for electrical circuit interlocking, indicator signal control, PLC feedback expansion, and varied industrial automation control systems.

What are the differences in dimensions and weight between 2-contact and 4-contact models?

Standard 2-contact models (such as LADN11C, LADN20C, LADN02C) have a width dimension A of 23 mm and weigh 0.030 kg, while 4-contact models (such as LADN22C, LADN40C) have a width dimension A of 44 mm and weigh 0.050 kg. Both series share dimensions B (38 mm) and C (47 mm).
