HARTING

HARTING rectangular connector housings in the Han series are typically rated IP65 or IP67, depending on the model. For example, the bulkhead-mount housing size 16 B (SKU 793XX6) is rated IP67, while the surface-mount housing size 16 B (SKU 793Y90) is rated IP65. The rating indicates protection against dust ingress and water jets (IP65) or temporary immersion (IP67). The seal material used is NBR (nitrile rubber), which provides resistance to oils and fuels. When selecting a housing, verify the IP rating against the application environment, especially if the connector will be exposed to washdown or outdoor conditions.

The Han 4A and Han 16B series differ in size, current rating, and contact capacity. Han 4A connectors, such as the modular kit SKU 793WR4, are rated for 10 Amps and accommodate 4+PE contacts (5 poles total) with a screw connection type. Han 16B connectors, like SKU 793WR6, are rated for 16 Amps and support 6+PE contacts (7 poles total) with screw connections. The 16B housing is physically larger, allowing more contacts and higher current. Both series are IP65-rated and use die-cast zinc or aluminum housings. Choose Han 4A for lower-power signal or control circuits and Han 16B for higher-power or mixed-signal applications.

HARTING M8 and M12 cordsets are available with PVC or PUR cable jackets. For example, the M8 cordset SKU 793TY9 uses a gray PVC jacket, suitable for flexing applications in dry or mildly oily environments. PUR jackets, as seen in some M12 cordsets, offer higher abrasion resistance and flexibility at low temperatures, making them suitable for robotic or moving cable tracks. The jacket material affects the cordset's temperature range, chemical resistance, and mechanical durability. Check the specific SKU's datasheet for exact temperature limits and flex-cycle ratings.

HARTING M12 connectors are available with A, B, D, and X coding, depending on the application. A-coding is used for sensor/actuator connections (e.g., 4-pin), B-coding for Profibus, D-coding for Ethernet (100 Mbps), and X-coding for Gigabit Ethernet (Cat6a, up to 10 Gbps). For example, the M12 to RJ45 cordset SKU 793TU4 uses X-coding and supports Cat6a performance. The coding ensures correct mating and prevents mismatching of signal types. When selecting an M12 connector, match the coding to the network protocol or device requirement.

Yes, many HARTING RJ45 cordsets are shielded to reduce electromagnetic interference (EMI). For instance, the Cat5e cordset SKU 793TL7 and the Cat6a cordset SKU 793TM1 are both shielded and rated IP20. Shielding is achieved via a metal connector housing and a foil or braid around the cable. Shielded cordsets are recommended in industrial environments with high electrical noise, such as near motors or drives. Unshielded versions may be available for less noisy settings. Verify the SKU's specifications for shielding type and grounding requirements.

HARTING rectangular connector housings typically use a dual-lever locking system. For example, the bulkhead-mount housing SKU 793XX6 and the surface-mount housing SKU 793Y90 both feature dual-lever locks. This mechanism provides secure closure and prevents accidental disconnection under vibration. The levers are made of metal or plastic, depending on the housing series. Some housings may also offer single-lever or screw-lock options. The dual-lever design allows tool-less operation and is common in Han 16B and larger sizes.
