Where this timer drops into the panel
The Omron H3Y-2-B DC12 5S is a fixed-range solid-state timer in the H3Y series, built as a DPDT (double-pole double-throw) output block with a 5-second timing window and a 12 VDC supply — the kind of device you plug into an 8-pin octal socket to sequence a conveyor, a lube pump, or a star-delta transition in a control panel. It is a mature, Active product on the Omron line, not a flagged end-of-life item — which matters when a storeroom is sizing a long-lived spare for a machine the floor plans to run another decade.
Timing range, output form, and what they mean for the buyer
The 5-second fixed range is the headline spec: the time interval is set at the factory, not by a front-face pot, so once it lands in the socket the timing window is locked — there is nothing for an operator to nudge out of calibration during a shift change. DPDT output gives two independently switched poles, so a single timer can drive a load and a status indicator simultaneously, or hand off between two discrete control paths in the same ladder rung; the 12 VDC supply rail matches common PLC-style control power in lower-voltage machinery cabinets. H3Y timers ship in Bulk package format, so the part comes ready for high-density bin stocking rather than a retail peg-out — the appropriate handling for a maintenance spare that will sit in a panel-shop drawer until a line goes down.
Lifecycle read and how to keep it on the BOM
Lifecycle status is Active and the stage is mature — the H3Y-2-B DC12 5S remains on the manufacturer's ordering book, not relegated to last-time-buy surplus channels. That is the green light a procurement planner needs before locking it into a long-running machine's bill of materials. Because the line is still active, the cleanest path is the standard quoted-to-order channel — independent distribution pulls against the BOM line, current pricing and lead time are confirmed at the RFQ stage, and the traceable stock carries full manufacturer pedigree.
