B-LINE E57LAL18A2EA – Frequently Asked Questions
1) Can the Eaton E57 proximity sensor E57LAL18A2EA be wired directly into a 120V or 240V AC circuit?
Yes. Model E57LAL18A2EA is a 2-wire AC sensor with a normally open output, and it operates across a 20-250V input range, so it drops straight into a 120V or 240V AC control loop in series with the load. Switching capacity is 250 mA at 250V, so keep the connected load, typically a relay coil or PLC AC input, under a quarter amp.
2) Is this Eaton E57 inductive sensor rated for washdown areas?
It is built for it. The E57LAL18A2EA carries NEMA 4, 4X, 6, 6P, 12 and 13 along with IP67 and IP69K, and the barrel is 303 stainless steel. IP69K is the high pressure, high temperature washdown rating, so it suits food processing and other sanitary lines rather than just dusty plant floors.
3) Does this Eaton proximity sensor need to be mounted flush in metal, or can it stick out?
It is an unshielded sensor, so it must be mounted non-flush with clearance of free space around the sensing face. Burying an unshielded barrel flush in a steel bracket will cause it to see the surrounding metal and false trigger. Unshielded construction buys you longer sensing distance than a shielded equivalent, at the cost of that mounting clearance.
4) Can I use this AC sensor to feed a 24V DC PLC input?
No. The E57LAL18A2EA is a 2-wire AC device running on 20-250V, so it will not switch a 24V DC sinking or sourcing PLC card. For a DC input card you need a 3-wire DC PNP or NPN version of the E57 series instead.
5) Will this sensor hold up in a cold warehouse or near an oven line?
Operating range on the E57 Premium+ sensor is -13 to 158 degrees F (-25 to 70 degrees C). That covers unheated docks and most ambient plant conditions, but it is not an oven-zone part. For radiant heat above 158 F you need a high temperature sensor instead.
6) Can a technician tell if this sensor is triggering without a meter?
Yes. The sensor has a 360 degree viewable LED, so the target indication is visible from any side of the barrel once it is mounted, which matters when the sensor is buried in a machine frame and you can only see one face of it.
7) How repeatable is the switch point on this Eaton inductive sensor?
Accuracy is within 3 percent of the sensing range, so on a positioning or counting application the trip point stays tight enough for typical machine indexing. Keep the target approach consistent, since an unshielded sensor's effective distance also varies with target material and size.
