HMI Solutions (X Series E-stop)

IDEC now offers a new series of E-stops that provide an even higher level of function and safety to customers. These 30mm XN E-stops are the first and only with exciting, new technology to make machines even safer.

Features include our unique “Safe Break Action,” which ensures NC contacts will open if the contact block is damaged or separated from the operator due to excessive force. Direct Opening Action ensures that even if the contacts are welded, the force applied to the button will directly open the contact. A Safety Interlock Mechanism keeps contacts open when the operator is locked.

Inspired by the lockout concept, the new XN series of padlock-type E-stops were developed to prevent unauthorized or accidental resetting of latched emergency stop switches, by allowing the use of up to 20 personal padlocks*. XN1E series E-stops save space behind the panel with depths of only 47.7mm for up to four contacts. And XN5E series E-stops only extend 21mm from the front of the panel, ideal for applications needing a low-profile design.

HMI Solutions (LBW Flush)

Welcome to the LBW series, a new breed of 22mm flush mount switch family that offers hundreds of styles and numerous features.

Available in face- or ring-illuminated pushbuttons, flush or extended pushbuttons, pilot lights, selector switches, and key selector switches, the LBW Series is perfect for applications for medical devices, food and beverage processing equipment, semiconductor equipment, demo equipment, home automation, and robotic control systems where a hygienic surface is required. A smooth surface design prevents particles and debris from accumulating and makes regular cleaning a breeze. LBW flush mount switches also remove the obstacles from busy control panels where a flat surface is desirable to allow frequent finger travels. The compact and space-saving design of the LBW series also enables breakthrough in stylish and modern design by reducing the machine’s panel size while enhancing its functionality and controllability.
