Why Choose the EMAS SIQ18NP1RC7 Square Inductive Sensor?
The EMAS SIQ18NP1RC7 is a compact 18 mm square non-flush inductive proximity sensor designed for reliable non-contact detection of metallic objects in industrial machinery and automation systems. As part of the EMAS SIQ Series square inductive sensor range, it combines a durable plastic housing, PNP normally-closed output and a generous 7 m pre-wired cable for flexible installation.
The SIQ18NP1RC7 provides fast, repeatable metallic target detection without physical contact, helping reduce mechanical wear in automated equipment. Integrated short-circuit, overload and reverse-polarity protection support dependable operation, while its IP67 protection rating makes the sensor suitable for demanding industrial environments where dust and moisture may be present.
With a nominal sensing distance of 8 mm, an operating voltage range of 10–30 V DC and a switching frequency of 400 Hz, the SIQ18NP1RC7 is well suited to position sensing, component detection, machine sequencing and material handling applications requiring a non-flush PNP normally-closed sensor.

Reliable Non-Contact Detection for Industrial Automation
Inductive proximity sensors detect conductive metallic targets by generating an electromagnetic field at the sensing face. When a suitable metal object enters the detection zone, the sensor changes its electrical output state without requiring physical contact, enabling repeatable position and presence detection while helping minimise mechanical wear.
The EMAS SIQ18NP1RC7 combines an 8 mm sensing distance with a compact non-flush square housing and PNP normally-closed output. Its 7 m cable provides additional installation flexibility where the sensor is positioned some distance from a junction box, PLC or control panel.
Typical Applications
- Machine position and end-of-travel detection.
- Metal component presence sensing.
- Conveyor and material handling systems.
- Packaging and assembly machinery.
- Automated production and manufacturing equipment.
- Machine tools and process equipment.
- PLC-controlled industrial automation systems.
