What it is and where it fits
The Omron E32T16WR2M.1 is a through-beam fibre optic sensor in the E32 series, terminated with a 2 m cable and housed to IP50. It detects by aligning a separate emitter and receiver across a gap, which is how the E32 through-beam style reaches its 3.9 m maximum sensing distance — long throw for a small-format fibre head. The body is 23 mm wide, 5 mm high, and 69 mm long, so the head drops into tight fixture brackets where a block-style photoelectric switch would not fit. Operating envelope is -40 °C to 70 °C, which covers unheated cabinets, freezer-adjacent lines, and most factory floors without derating.
IP50 is the headline to read carefully
IP50 means dust-protected but not water-resistant — a panel-side or enclosed-fixture rating, not a washdown or outdoor rating. Three same-series fibre optic sensors carried as peers — the E32T22S2M, E32TC200A2M, and E32T14LR2M.1 — are all rated IP67, so the seed is the odd one out on ingress, not the family default.
Range and termination in plain terms
3.9 m of through-beam throw outpaces typical diffuse-reflective fibre heads and reaches across conveyor sections, pallet stops, or small-part feeders without an extra reflector. The 2 m pigtail is sized for routing back to a remote fibre-optic amplifier mounted on a DIN rail or in a control cabinet — pair the head to the amplifier spec, not to a generic photoelectric input.
