M12 B-Coded Field-Wireable Receptacle, 2 Positions, Screw Termination
The TE Connectivity T4111402021-000 is an M12 B-coded receptacle with male pins, designed for field-wireable screw termination in industrial automation networks. This 2-position connector carries a 4A current rating per contact at 250V, with gold-plated mating surfaces (3.00µin) on zinc alloy contacts. The nickel-plated brass shell and threaded coupling nut provide IP67 sealing when mated, making it suitable for washdown environments in food processing, packaging, and machine tool applications. The glass-filled PBT backshell accepts cable diameters from 0.236" to 0.315" (6.00mm to 8.00mm), and the operating temperature range of -40°C to 85°C covers most factory floor conditions.
B-Coding and Pin Configuration
The B orientation (B-coding) is the standard keying for Profibus and actuator/sensor networks, with pin 1 typically assigned to V+ and pin 2 to GND in a 2-position configuration. This coding prevents cross-mating with A-coded (sensor) or D-coded (Ethernet) connectors, ensuring correct wiring in mixed-cable installations. The M12-2 shell size confirms the insert arrangement matches standard B-coded cordset patterns.
IP67 Sealing and Environmental Fit
Rated IP67 - Dust Tight, Waterproof, this connector withstands temporary immersion up to 1 meter for 30 minutes when properly mated with a matching B-coded cordset. The threaded fastening type provides vibration-resistant coupling, while the unshielded design means it's intended for non-EMI-critical signal or power circuits. The nickel shell finish and gold-plated contacts resist corrosion in humid or washdown environments, though the 3.00µin gold flash limits mating cycle life to moderate duty (typically 50-100 cycles).
