Turck NI50-CP80-FZ3X2 50 mm non-flush 2-wire inductive sensor

SKU CH-7WXJ-BXTHS MPN NI50-CP80-FZ3X2

50 mm non-flush inductive proximity sensor with 2-wire output, 20…250 VAC or 10…300 VDC supply, and ≤2 % repeat accuracy

  • TypeSensors
  • Reliable detection up to 50 mm range
  • Flexible wiring with programmable 2-wire output
  • Broad voltage compatibility from 20 to 250 VAC
  • Consistent performance within 2 % repeat accuracy
  • Robust surge handling up to 8 A capability

50 mm non-flush inductive proximity sensor

The Turck NI50-CP80-FZ3X2 detects metal targets at a rated switching distance of 50 mm without needing flush mounting. It operates on 20 to 250 VAC or 10 to 300 VDC and uses a programmable 2-wire output. Repeat accuracy is within 2 % of full scale.

Installation suitability

The non-flush design suits applications where the sensor face cannot sit level with the surrounding metal. The 2-wire connection simplifies wiring for AC or DC supplies. Builders needing a flush-mountable housing or a 3-wire PNP/NPN output should look elsewhere.

Switching frequency of 0.02 kHz

The sensor switches at 0.02 kHz, limiting it to slow-moving or presence-detection tasks. Faster cycles will exceed this rate and cause missed signals. Verify that the application speed stays within this limit before specifying the part.

Questions about this item

What supply voltage must my system provide for the 2-wire output to operate?

The sensor accepts 20…250 VAC or 10…300 VDC, so your supply must fall within one of those ranges.

If I keep my existing St37 mounting bracket, will the 50 mm switching distance change?

St37 has a correction factor of 1, so the rated 50 mm distance is unchanged with that material.

How can I verify the sensor is switching reliably after installation?

Measure repeat accuracy; it should stay within ≤ 2 % of full scale, and hysteresis should remain between 3…15 %.
