These dual-purpose slimline gender changers and socket savers are designed to connect mismatched Centronics connectors and extend the lifespan of cables and ports by absorbing wear from frequent connections. Their low-profile design helps reduce strain on stressed computer ports, and full shielding provides protection in environments with high electrical interference. The 36-position connector is commonly used with printer cables and ports, while the 50-position connector is typically used in Telco and SCSI-1 applications.
