Omron
The Omron D4NS-4BF is a key-operated resin door switch featuring a resin head and an adjustable direction of operation. This slow-action component provides two NC door contacts, operates within an ambient temperature range of -30 to 70 °C, and includes an M20 conduit size with a terminal block connection method. Built with an IP67 degree of protection, the housing lacks a guard-lock, LED indicator, and cable length. Submit the exact part number, quantity, and application requirements for a quote.
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Omron references — within one business day.
