Safety Door Switch [D4BS]
Caution
Product Description
Blocks the control circuit by directly opening the contact by using the dedicated operation key when opening a protective door, such as for machine tools.
[Features]
· Approved by EN (TÜV) standards compliant with CE markings.
· Approved by UL, CSA.
· Opening the switch contact at the time of opening protective cover by using the direct opening mechanism (only on NC contact side).
· Approval of EN standard direct opening operation is shown by marking the switch.
· Prevents error operation and fake operation by using a dedicated operation key.
· A wide temperature range of -40 to +80°C.
· The protective structure of the switch enclosure is approved by IP67 (EN60947-5-1).

Note: The above values are initial values.
*1. This protection structure is based on a test method based on the standard (EN60947-5-1), so please check the sealing performance in the actual environment and conditions of use in advance.
The Limit Switch box body is protected from the intrusion of dust and water, but please use it in a place where cutting chips, water, chemicals, etc. will not come into contact with the operation key insertionport in the head part.
It may cause early wear, damage, and failure.
*2. The durability conditions are at an ambient Limit Switch of 5 to 35°C and an ambient humidity of 40 to 70% RH.
*3. Please ensure that you use it safely.
