About combination of connector and contact shape

[WT]For S Type (plug with integrated socket contact) of the series, the contact shape name is omitted for all shapes such as PF and RM, and they are simply P, R, etc.
- * Pin contact products have exposed electrodes, which may cause electric shock or short-circuit accidents if used on the "power supply side."To prevent accidents, use a socket contact product for the [Power Supply Side] and a pin contact product for the [Power Receiving Side].
