Reflex sensor with 120 mm range

The Wenglor HK12PA is a PNP reflex sensor designed for presence detection in industrial automation. It operates on a 10...30 V DC supply and delivers a switching frequency of 1300 Hz with a response time of 385 µs. The housing is fully encapsulated plastic rated IP67 for harsh environments. A 2 m, 4-wire cable provides the electrical connection.

Suits short-range detection on 24 V systems

This sensor suits applications needing adjustable detection between 18...120 mm with a red light source. It is not for installations requiring longer sensing distances or NPN output logic. Buyers needing higher ambient light immunity above 10000 Lux or a wider temperature span than -25...60 °C should look elsewhere.

PNP antivalent output with 100 mA switching

The single specification that decides fit is the PNP NO/NC antivalent output rated at 100 mA switching current. It includes short-circuit, reverse-polarity and overload protection with a voltage drop below 2,5 V. Verify that your controller accepts this PNP logic and current level before purchasing.

Questions about this item

What supply voltage must my control cabinet provide for the HK12PA PNP reflex sensor?

The sensor operates on 10...30 V DC, so any cabinet rail within that range will power it.

Will the sensor's red light spot still detect targets if I keep my existing 10000 Lux ambient lighting?

Yes, the spec allows up to 10000 Lux ambient light without affecting the 120 mm sensing range.

How can I verify the HK12PA is switching correctly after wiring the 4-wire cable?

Turn the potentiometer until the output toggles at your desired distance; the 1300 Hz switching frequency gives a clean on/off signal at the PNP output.
