Obsolete — Sourcing Reality for the K8AB-TH11S
Omron lists the K8AB-TH11S AC100-240 as obsolete. This unit is sourced through independent distribution channels. Quantities are lot-specific; availability and current pricing are confirmed at the time of RFQ against your BOM line.
Trip Range and Contact Rating — What They Mean for Your Loop
The adjustable trip range spans 0°C to 399°C, covering most industrial process monitoring for overtemperature or undertemperature on bearings, windings, or fluid lines. The SPDT relay output is rated 3 A at 250 VAC — enough to directly switch a small alarm horn, pilot light, or PLC input, but for larger loads you'll want an interposing contactor.
Panel Fit and Supply Voltage
Snaps onto standard 35 mm DIN rail — no panel cutout needed, which simplifies retrofits in crowded enclosures. Accepts 100 to 240 VAC supply, so it works across common plant voltages without a separate control transformer. Rated for -10°C to 55°C ambient — fine for most indoor panel environments but not for direct outdoor or washdown placement.
