SICK KTM-MB31194P Contrast Sensor 12.5 mm 10 kHz

Industrial Contrast Sensor for Print Inspection

The SICK KTM-MB31194P detects contrast marks at a 12.5 mm sensing distance with a 2 mm light spot. It operates on 12 V DC to 24 V DC and switches at 10 kHz with a 50 µs response time. The rectangular ABS housing measures 12 mm x 31.5 mm x 21 mm and carries an IP67 enclosure rating. A 2 m open-end cable provides four-wire connection.

Suited for High-Speed Mark Detection on Web Lines

This sensor fits packaging lines and label verification where fast, reliable switching is required. Both PNP and NPN outputs with light/dark switching cover most PLC input cards. Buyers needing longer range, analog output, or colour differentiation should look at other sensor families. The fixed 2 m cable may not suit installations requiring connectors or custom lengths.

Verify Supply Voltage

Confirm your control system accepts 12 V DC to 24 V DC with ripple below 5 Vpp and can sink or source up to 50 mA per output. Ensure the 12 mm x 31.5 mm x 21 mm housing fits the available space and that the 12.5 mm ± 3 mm sensing window matches the target position. The IP67 rating suits wet or dusty environments but check chemical compatibility with ABS housing material.
