The Omron J7KNA-09-10 24VS is an electrical contactor from the J7KNA series, used to switch motor loads and resistive circuits in control panels. It carries a 24 VDC coil, which means the coil pulls in at nominal 24 VDC and drops out below the release threshold typical for this class. The part number breaks down as a J7KNA frame, 09 frame size, 1 NO + 0 NC main pole configuration, with a 24 VDC coil.
The J7KNA-09-10 24VS is classified at a mature lifecycle stage. That means it is not in active new-product introduction, but it remains available through the independent distribution channel.
As a contactor, the J7KNA-09-10 24VS is sized for switching loads within its rated thermal current and utilization category. The 09 frame size typically corresponds to a rated operational current around 9 A in AC-3 duty (motor switching), though the exact rating should be confirmed from the nameplate or full datasheet. The 24 VDC coil makes it a direct fit for 24 VDC control systems common in industrial panels — no additional power supply conversion needed. The 1 NO + 0 NC main pole arrangement means it switches one power circuit (single-pole normally open), suitable for single-phase motor loads, resistive heaters, or as a pilot-duty contactor in larger starter assemblies.
The 24 VDC coil integrates directly with PLC digital outputs or relay modules supplying 24 VDC. For inductive loads switched by the contactor, verify that the load circuit includes appropriate overcurrent protection (fuse or circuit breaker) sized per the contactor's rated short-circuit current. The J7KNA series uses spring-cage or screw terminals depending on the variant; confirm the termination type on the specific unit before wiring.
