FAQs
1What size emergency-stop buttons can the BD-D56 accommodate?
The BD-D56 features a 54.5 × 64 mm internal cavity designed for elongated mushroom emergency-stop buttons up to 45.5 mm in diameter. Please confirm the complete button dimensions before ordering.
2Is it compatible with different emergency-stop reset mechanisms?
Yes. Its optimized dual-contour cavity accommodates both push-type and twist-reset elongated mushroom emergency-stop buttons commonly used on industrial control panels.
3Does the mounting base need to be removed after maintenance?
No. The split design allows the adhesive base to remain permanently mounted on the cabinet. Only the transparent cover needs to be attached or removed during lockout procedures.
4Will the transparent cover remain clear in oily production environments?
The cover is made from transparent glass-resin PC with oil-resistant and UV-resistant properties, helping reduce fogging and yellowing during long-term industrial use.
5Can multiple maintenance employees lock out the same emergency-stop button?
Yes. The integrated multi-padlock lug accepts several safety padlocks, supporting group lockout procedures in which each authorized employee applies an individual lock.
