D4ER-1A21N Omron

Oil-Resistant Limit Switches D4ER- N Even Better Oil Resistance Than D4E-N Switches Material combining HNBR and fluororubber used for superior resistance to oil. Prevents ingress of cutting oil from moving sections. Fluororesin cable that withstands cutting oils is provided as standard. Pre-wired and connector cable models available. Smartclick connectors for easy connection. Minute load model with gold cladding is optimal for electronic control. Approved by EN (TV). For the most recent information on models that have been certified for Same mounting pitch as D4E-N Switches. safety standards, refer to your OMRON website. IP67G degree of protection (JIS C 0920 Annex 1). * * The IP67G is the degree of protection which is defined according to Be sure to read Safety Precautions on pages 37 to 38 and the JIS (Japanese Industrial Standards). Safety Precautions for All Limit Switches. The IP67 indicates the same level of protection as defined by the IEC, and the G indicates that a device has resistance to oil.
