Flush mounting means it can be embedded in metal without false triggers from the surrounding material, which is the usual requirement for tool changers, gripper jaws, or end-of-stroke detection in tight bores. Rated for 10-30 VDC with a PNP normally-closed (NC) switching output rated to 200 mA — the NC logic means the output is ON when no target is present, so a broken wire or sensor failure reads as a target-present condition, which is the fail-safe choice for safety-monitored position feedback. The 1500 Hz switching frequency handles fast-moving targets on pick-and-place cycles or spindle speeds without missed pulses. IP65/IP67 enclosure rating means the stainless steel body and PA sensing face tolerate washdown spray and temporary submersion — suitable for food-and-bev lines, coolant splash on machining centers, or outdoor conveyor stations. The M8 3-pin connector keeps field replacement quick without opening the panel gland. This class of inductive proximity sensor is used for non-contact position detection of metal targets in automated machinery — end-of-stroke on pneumatic cylinders, part-presence on transfer lines, or tool-position feedback in machining centers. The flush 8 mm body fits into drilled pockets in steel manifolds or fixture plates without stand-off brackets.","metaTitle":"Festo SIEN-M8B-PO-S-L Inductive Proximity Sensor, PNP NC, 1.","metaDescription":"Festo SIEN-M8B-PO-S-L inductive proximity sensor, flush mount, 1.5 mm range, PNP normally closed, M8 3-pin, IP65/IP67, 10-30 VDC.
