HAS8141-16 is a TURCK field-wireable M12 male connector, straight, 4-pin, A-coded, for 6...8 mm cable with IDC terminals.

• Connector: M12, male, straight, A-coded, 4-pin, gold-plated CuZn contacts
• Ratings: 6 A, 50 V
• Connection: IDC terminals, conductors up to 0.75 mm², cable diameter 6...8 mm, M12 x 1 screw-in thread
• Housing: black PA body and contact carrier, nickel-plated brass (CuZn) coupling nut, FPM/FKM seal
• Environment: IP67 (screwed together); -5...+50°C fixed

FW-M12KU5W-G-ZF-ME-SH-9 is a field-wireable M12 female connector for PROFIBUS-DP. It is assembled on site onto a cut length of bus cable, so a damaged connector or an awkward cable run can be repaired without replacing a whole cordset. The cable screen is picked up by an iris spring and carried through to the metal housing.

• Connector: M12 × 1 female, straight, B-coded, 5-pin, gold-plated CuZn contacts
• Bus: PROFIBUS-DP up to 12 Mbit/s, overall shield connected via iris spring
• Rating: 4 A, 125 V, contact resistance ≤ 5 mΩ, over 100 mating cycles
• Termination: screw/clamp connection for 0.37...0.75 mm² cores, cable diameter 7...9 mm
• Housing: nickel-plated die-cast zinc with M18 × 1 screw-in thread, FPM/FKM seal
• IP67 when screwed together, −40 °C to +85 °C

It is used to terminate PROFIBUS-DP segments at drives, remote I/O and field devices, and for repairs in cabinets and on machines where a pre-moulded cordset cannot be routed. No crimping tool is needed — the cores are clamped and the gland is tightened by hand.
