Description
One-Piece Weather-Sealing Plug for Unused 4-Pin DT-Style I/O Module Ports
Every unused port on your I/O module is a liability. Left open, a 4-pin DT-style socket loses its weather seal, letting in water, dust, and debris that lead to corrosion, shorts, and premature failure.
Our patent-pending sealing plug solves this with a true one-piece design, the only one of its kind on the market. Compatible with 4-pin Deutsch DT sockets, it seals unused ports and restores the socket’s original weather-sealing integrity, keeping your module protected in the field. It also works on DT sockets in cable-assembly applications, maintaining the seal wherever a port would otherwise sit exposed.
Engineered as a direct, reliable fit for 4-pin DT sockets, it installs in seconds with no tools or extra components.
Additional configurations are on the roadmap, including versions with integrated terminating resistors and alternate pin arrangements, giving you a single, trusted source as your needs grow.
