D4BS
Safety-Door Switch
• The special operation key activates a direct opening mechanism to
open the contacts and shut off control circuits when protective doors
are opened on machine tools or other equipment
• Conforms to EN (TÜV) standards corresponding to the CE marking.
• Certified by UL and CSA standards.
• The Switch contact is opened by a direct opening mechanism (NC-
contacts only) when the protective cover is opened. The EN-certified
direct opening mechanism is indicated by
on the Switch
• Malfunctions and false operation prevented by special Operation Key
• Wide temperature range specifications: -40 to 80°C
• Degree of protection of the switch box: IP67 (EN60947-5-1)
• Series includes models with gold-plated contacts for handling the
microload range
