Han Coding Pin "Insert In Hood/Housing" Male

The HARTING 09300009908 Han Coding System Guide Pin is a mechanical coding accessory for HARTING Han® connector assemblies, designed to prevent accidental mismating of connectors in applications where multiple similar-looking connector pairs are used in close proximity. Installed in the hood or housing of the connector, the guide pin works in conjunction with a guide bushing on the opposite connector half: only connectors whose guide pin and bushing positions match can be physically mated. This mechanical interlock eliminates the risk of connecting the wrong cable to the wrong equipment, which can cause equipment damage, process faults, or safety incidents.

The Han Coding System: Preventing Connector Mismating

In industrial installations with multiple Han® connectors of the same series and size — machine tool panels, production lines, modular equipment systems — each connector pair can appear identical. Without a coding system, an operator under time pressure could accidentally mate the wrong connectors. The HARTING Han Coding System addresses this at the mechanical level: differently positioned guide pins and bushings make it physically impossible to mate a coded connector with any connector that does not share the same coding position. No reliance on colour coding, labelling, or operator awareness is required.

The coding system is widely used in combination with Han E® insert assemblies and Han® B series housings wherever multiple connector pairs of the same size are installed on the same panel or machine.

Guide Pin Construction and Installation

The guide pin (this product) is the male component of the coding pair. It is installed into the hood or housing — the "insert in hood/housing" application described in the datasheet. The corresponding female component is a guide bushing, installed on the opposite (base/insert) side of the connector pair. The pin and bushing must occupy matching positions in both connectors for mating to be mechanically possible.

The pin is a steel component, machined for precise dimensional consistency. Steel construction provides the mechanical robustness required to withstand repeated mating cycles and the incidental contact forces that occur when operators attempt to mate mismatched connectors.

Compliance

RoHS compliant with exemption 6(a)/6(a)-I — Lead as an alloying element in steel for machining purposes (up to 0.35% lead by weight) and in batch hot dip galvanised steel components (up to 0.2% lead by weight). This exemption applies to the steel body of the guide pin and is distinct from the copper alloy exemption 6(c) applicable to electrical contacts. ELV compliant with the same exemption. REACH SVHC substance Lead is present; REACH Annex XIV and Annex XVII substances are not contained. China RoHS: 50. California Proposition 65: Lead is present. Manufactured in Germany.
