RJE38 CAT5 Modular Jacks

Amphenol Commercial RJE38 CAT5 Modular Jacks are single-port modular jacks that meet CAT5 performance standards per EIA-568-C.2. The RJE38 series supports a 100BASE-T Ethernet data rate and transmission frequencies up to 100MHz. The available shielding enhances electromagnetic interference (EMI) performance and network speed verification. These Amphenol connectors are highly durable, with 750 mating and unmating cycles. These modular jacks also support an operating temperature of -55°C to +85°C, suitable for a wide range of environmental conditions. The series supports CAT3/5 Ethernet protocols and features a common stacked through-hole housing.
