4-Port Shielded RJ45 Jack for Industrial Ethernet
The TE Connectivity 2041376-2 is a 4-port modular jack with 8P8C (RJ45) contacts, designed for Cat5 Ethernet applications. It sits in the 2041376 base series as a right-angle, shielded variant with integrated EMI fingers for noise suppression in electrically noisy environments — think factory floor panels, machine control cabinets, or PoE switches where signal integrity matters. Each port carries green-yellow LEDs for link/activity status, letting a technician spot a dead port without cracking the enclosure. Board locks on the through-hole solder tails anchor the jack to the PCB, so cable strain from a stiff Ethernet patch cord doesn't lift the connector off the board during vibration. The glass-filled PA46 housing stands up to reflow temperatures and industrial cabinet heat.
Cat5 Rating and Shielding — What It Means on the Line
Rated Cat5, this jack supports 100 MHz signaling — enough for 100BASE-TX and 1000BASE-T (Gigabit) Ethernet over short to moderate cable runs. The shielded shell with EMI fingers bleeds common-mode noise from the cable shield to the chassis ground before it reaches the PHY, which makes the difference between a link that holds and one that drops packets near a VFD or welding line. Tab direction up and down means the latch on a standard RJ45 plug engages from either side — no fumbling with orientation when you're reaching blind into a cabinet.
