Overview
The Allen-Bradley 1585D-M4DC-SH is a shielded M12 insulation displacement connector (IDC) designed for rapid field attachment to Ethernet cables in industrial automation environments. This straight male connector features a robust zinc die-cast body and supports toolless installation without hand tools, making it ideal for maintenance technicians and system integrators who need fast, reliable cable termination in hazardous or IP67-rated locations.
Key Features
- 4-pin D-coded M12 form factor for EtherNet/IP and industrial Ethernet applications
- Shielded design with zinc die-cast housing for EMI protection and harsh-environment durability
- Toolless insulation displacement (IDC) installation—no crimping or hand tools required
- IP67 rated enclosure type—sealed against dust and water ingress for outdoor and washdown environments
- Operating temperature range -25 to +85 °C (-13 to +185 °F) with installation temperature -5 to +50 °C
- Supports twisted-pair Ethernet cables with high noise immunity and robust signal integrity
