Antaira LMP-1204G-SFP-bt-T-CC 12-Port Gigabit Managed PoE++ Switch with 8x PoE++, 4x SFP, Conformal Coating and -40 to 75 °C

Some outdoor and process cabinets let in condensation, dust or airborne contaminants that can attack bare circuit boards over years of service. The LMP-1204G-SFP-bt-T-CC is the conformal-coated build of the LMP-1204G-SFP-bt-T in the Antaira LMP-1204G-SFP-bt series, a 12-port Light Layer 3 managed industrial switch rated -40 °C to 75 °C for surveillance, ITS, utility, water treatment, oil and gas and factory automation networks.

Four 10/100/1000 RJ45 ports deliver IEEE 802.3bt PoE++ at up to 90 W per port, four more deliver IEEE 802.3at/af at up to 30 W, and four 100/1000 SFP slots carry fiber uplinks. The PoE budget is 240 W on 48 to 55 V DC. Store-and-forward switching runs on a 24 Gbps fabric with an 8K MAC table, and the firmware covers static routes, DHCP Option 82, VLANs, QoS and IGMP v1/v2/v3 for up to 1024 groups.

ITU-T G.8032 ERPS v1/v2 restores the ring in under 50 ms, with STP, RSTP, MSTP and LACP also available. Redundant 48 to 55 V DC inputs land on a removable 6-contact terminal block with overload current and reverse polarity protection, a 24 V DC, 1 A relay contact reports faults, and the switch draws 12.5 W. Management runs over the web console, Telnet, CLI or SNMP.

The LMP-1204G-SFP-bt-T-CC sits in an IP30 metal case for DIN-rail or wall mounting. Antaira lists FCC, CE, UL 61010-1 and NEMA TS2 approvals and covers it with its 5-year warranty. The uncoated LMP-1204G-SFP-bt-T carries the same rating, and the LMP-1204G-SFP-bt-24-T accepts 12 to 55 V DC. We supply and specify the switch, and can pre-configure IP addressing, VLANs and ring settings on request.
