The Omron E3ZM-CL61H 2M is a retroreflective photoelectric sensor from the E3ZM series, designed for detection of opaque objects in environments that demand high ingress protection. It provides an NPN output with selectable dark-on or light-on logic and an adjustable sensing distance of 10 mm to 100 mm. Rated IP67 and IP69K, this sensor withstands high-pressure washdown and submersion, making it a natural fit for food, beverage, and pharmaceutical packaging lines where frequent cleaning cycles are standard. The 1 ms response time, coupled with a 650 nm red LED light source, allows reliable detection at moderate line speeds; a PLC scan cycle of 10 ms typical in these applications will capture the pulse with adequate margin. Supply voltage of 10 V to 30 VDC; connection via cable.
For a BOM line that specifies an NPN retroreflective sensor with IP69K, this part is a direct fit. Submit an RFQ for current pricing and lead time; standard availability is expected.
Mounting and optical alignment follow standard retroreflective practice: the sensor emits a red spot (650 nm) that reflects from a separate reflector (not supplied). The adjustable sensing range is set via the internal potentiometer; a 10–100 mm adjustment window suits short-range detection where precise object presence or gap must be established. The cable exit is fixed; allow enough slack to reach the controller. Spring-cage or screw terminals are typical; conductors are color-coded per Omron standard. No auxiliary power or load resistor is required for the NPN open-collector output at 10–30 VDC.
