SICK Block Inductive Proximity Sensor M20 x 1.5, PNP Output, 30 V DC, 40 mm Detection Range IQ40-40NPOKK0S

SICK IQ40-40NPOKK0S is a block-style Inductive Proximity Sensor designed for industrial automation and control applications. Featuring a 40 mm sensing range, this sensor reliably detects metal objects in various manufacturing and processing environments. The sensor body measures 118 mm in length, with a width and depth of 40 mm, and is equipped with a plastic housing that complies with IP67, IP68, and IP69K protection standards, ensuring resistance to water, dust, and high-pressure cleaning.

This model uses a PNP output configuration and operates on a maximum supply voltage of 30 V DC, capable of switching currents up to 200mA. It supports non-flush mounting with screw terminals, facilitating robust mechanical and electrical installation. The operating temperature range from -25°C to 85°C allows it to function effectively in harsh conditions. The sensor features an extended sensing range of 20 to 40 mm, making it versatile for presence detection, positioning, and end position monitoring in automation systems.

The IQ40 series offers a push-lock mounting system that allows tool-free installation and quick replacement. The sensor head can rotate in five directions to adapt easily to various setups. Four corner LEDs provide clear indication of sensor status from different angles, improving monitoring and troubleshooting efficiency.

Typical industrial applications include press tool presence detection, car body positioning, skid detection, rack identification, discrete mechanical position detection, wear detection on conveyor clamps, and control of wrapping and conveyor belt processes. The sensor's robust design ensures long service life and stable operation even in environments exposed to shocks, vibrations, and electromagnetic interference.

Compact block style with M20 x 1.5 thread size for flexible mounting. Plastic housing rated IP67, IP68, and IP69K for harsh environment protection. Capable of detecting metallic materials within 20 mm to 40 mm range. Operates on 30 V DC supply voltage with a maximum switching current of 200mA.
