FAQs
1What size emergency-stop button is compatible with the BD-D57?
The BD-D57 is designed for oversized mushroom emergency-stop buttons with a 57 mm mounting-hole diameter. It accommodates both push-reset and twist-reset button styles.
2Does the mounting base need to be removed after maintenance?
No. The dedicated base is designed to remain permanently mounted on the control panel. Only the transparent lockout cover needs to be attached during maintenance and removed afterward.
3Is the BD-D57 suitable for equipment exposed to continuous vibration?
Yes. Its 3 mm thick glass-resin polycarbonate construction provides high impact resistance and structural rigidity, helping resist cracking and deformation in continuous-vibration environments.
4Will the transparent cover remain clear in oily workshop conditions?
The glass-resin PC material offers oil-resistant and UV-resistant properties, helping minimize fogging, discoloration, and yellowing during long-term industrial use.
5Can multiple employees lock out the same emergency-stop button?
Yes. The extended multi-padlock locking lug accepts several safety padlocks, supporting group lockout/tagout procedures in which each authorized employee applies an individual lock.
