Frequently Asked Questions
What's the advantage of metal housing?
Metal housing provides: better mechanical protection against impact, higher temperature resistance, better EMI/RFI shielding, and longer life in harsh industrial environments. Choose for demanding applications.
Why 3NC instead of 4NC?
3NC provides triple redundancy for safety circuit (sufficient for Category 4). 4NC provides quad redundancy. Both achieve Category 4/PL e when properly applied. 3NC is more cost-effective for most applications.
What's the lock force rating?
1000N (100kg/220lbs) holding force. Sufficient for most guard locking applications. For higher force requirements (large guards, high-risk), consider D4NL series with 1300N rating.
Can this be used outdoors?
Yes, IP67 rating and metal housing suit outdoor use. Ensure conduit entries are properly sealed. Consider stainless steel version for corrosive environments (marine, chemical).
