What the seed is, and what it switches
The Square D / Telemecanique XS8E1A1PAM8 is a rectangular inductive proximity sensor from the OSICONCEPT XS8 family, front-face sensing, 3-wire PNP normally open, intended to detect metal targets on industrial machinery and signal them as a switching event to a PLC or controller input.
Sensing head and timing
Front-face unshielded sensing with a 15 mm rated range, the head gives a 2000 Hz maximum switching frequency, which is the number that governs how fast a passing target can be detected on a conveyor or indexing table without missing a pulse.
Electrical interface and wiring
Power is 12 to 24 VDC across three wires, output is PNP normally open terminated on a 3-pin nano M8 connector, and the sensor carries a 100 mA maximum load current with an integral LED for state indication, so the M8 pigtail drops directly into a standard nano-style input block without re-termination.
Housing, environment, and approvals
The 26 mm W x 13 mm D x 26 mm H PBT body is rated NEMA 1/4X/12 and IP67, and the operating range is -13 to 158 deg F, which covers ordinary washdown and most factory floor ambient bands without derating. The unit carries UL, CSA and CE approvals.
Where this class of part sits
Block-style inductive sensors of this class are used as end-of-travel, position-confirm and part-present detectors on assembly lines, packaging machinery and material handling cells, where a non-contact metal target has to be read at short range into a 24 V logic input.
Same-family siblings worth knowing
The XS8C1A1PAL2 sibling runs 25 mm range on a 2 m PVC cable at 1000 HZ, and the XS8D1A1PAL2 runs 60 mm range at 150 HZ; this 26 x 13 x 26 mm block with a 15 mm head at 2000 HZ on a nano M8 connector is the only one of the three combining that footprint, range and termination.
This part has a current lifecycle stage, so it is ordered to the BOM line as a current production unit; the record carries a Prop 65 warning for diisononyl phthalate and di-isodecyl phthalate that ships with the documentation. No official replacement or second-source order code is identified on this record, so any cross to a different XS8 body must be re-checked against range, termination and timing numbers, not the family name alone.
