SICK RZT7-03ZUS-KWB T-Slot Cylinder Sensor

Overview

The SICK RZT7-03ZUS-KWB is a reed-switch T-slot cylinder position sensor engineered for direct mounting into the T-slot groove of pneumatic cylinders, delivering reliable end-position and stroke-limit detection across industrial automation lines. Carrying SICK part number 1070867, the SICK RZT7-03ZUS-KWB provides an AC/DC normally-open (NO) switching output over a 2-wire, 5 m stripped cable, making it a drop-in solution for OEM machine builders and maintenance teams standardizing on the well-proven RZT7 cylinder sensor platform. Its compact 29.5 mm housing, IP65/IP67 enclosure rating, and wide 5 V–30 V AC/DC supply range let plant engineers integrate it into both new pneumatic circuits and legacy control panels without redesigning the surrounding electrical architecture.

As the official authorized partner and exclusive regional representative for SICK, Seven Star LLC proudly supplies the SICK RZT7-03ZUS-KWB T-Slot Cylinder Sensor to industrial buyers throughout Oman and the wider GCC. Facility engineers and procurement teams in Muscat, Sohar, and Salalah rely on Seven Star LLC for genuine SICK stock, full manufacturer warranty coverage, and local technical support — a level of assurance that grey-market resellers of the SICK RZT7-03ZUS-KWB simply cannot match.

Operating Principle

The SICK RZT7-03ZUS-KWB operates on straightforward reed-switch technology. A permanent magnet embedded in the pneumatic cylinder’s piston travels along the bore as the piston strokes; once that magnet enters the sensor’s typical 3 mT response sensitivity zone, the sealed reed contacts inside the SICK RZT7-03ZUS-KWB close and the normally-open output switches, signaling the controller that the piston has reached a defined position. The sensor’s typical 10 mm overrun distance and ±0.1 mT reproducibility keep the switching point consistent cycle after cycle, which matters enormously in high-throughput pneumatic sequencing where end-position accuracy drives cycle time and part quality.

Because switching is achieved through a sealed magnetic reed contact rather than a mechanical limit switch or optical emitter, the SICK RZT7-03ZUS-KWB has no moving parts exposed to the process, no wear surfaces in contact with the piston, and no light path to become contaminated by oil mist, dust, or coolant spray common on shop floors. The practical consequence is a maintenance-free position feedback element that continues delivering a clean switching signal at up to 400 Hz switching frequency over millions of cycles, with the sensor’s IP65/IP67 enclosure rating protecting the internal reed and wiring from washdown and airborne contaminants alike.

Engineering Design of the SICK RZT7-03ZUS-KWB

The SICK RZT7-03ZUS-KWB is housed in a slim, T-slot-profile Grilamid LVX-65H SST plastic body measuring 29.5 mm in length, sized to slide directly into the T-slot groove machined into the cylinder barrel and lock in place with a single mounting screw – no separate mounting bracket or clamp is required for standard T-slot cylinders. A status indicator LED on the housing gives an immediate visual confirmation of the switching state during commissioning and troubleshooting, letting technicians verify correct sensor position without disconnecting the control circuit.

Electrical connection on the SICK RZT7-03ZUS-KWB is a fixed 2-wire, 5 m PVC cable with stripped conductor ends (0.12 mm² conductor cross-section, Ø2.9 mm overall cable diameter) exiting axially from the rear of the housing, simplifying routing through cable carriers and along cylinder bodies in confined machine frames. The sensor accepts a wide 5 V to 30 V AC/DC supply with a voltage drop of ≤3.5 V and continuous current of ≤100 mA, giving system integrators flexibility to wire the SICK RZT7-03ZUS-KWB directly into either AC or DC control circuits without an interposing relay, while shock and vibration ratings of 30 g / 11 ms and 10–55 Hz at 1 mm keep the sensor stable on cylinders subject to rapid, repetitive strokes.

Key Features

The SICK RZT7-03ZUS-KWB combines a compact form factor with rugged electrical and mechanical specifications suited to demanding pneumatic automation environments.

• The sensor delivers a normally-open (NO) reed switching output compatible with both AC and DC control circuits from 5 V to 30 V.
• A sealed reed-switch mechanism provides contactless, wear-free position sensing with no exposed moving parts.
• The IP65 and IP67 enclosure ratings protect the sensor against dust ingress and temporary water immersion on washdown-duty machinery.
• An ambient operating temperature range of –30 °C to +70 °C supports installation in both outdoor GCC ambient conditions and heated process areas.
• The fixed 5 m, 2-wire PVC cable with stripped ends removes the need for separate connector hardware on most retrofit installations.
• A built-in status indicator LED simplifies commissioning, position verification, and field troubleshooting.
• The T-slot housing profile mounts directly into the cylinder groove, compatible with SICK’s broader RZT7 accessory range including mounting clamps and quick-disconnect cable sets.
• Full compliance with EU, UK, ACMA, and Moroccan declarations of conformity, China RoHS, and cULus certification supports use in multinational engineering specifications.

Industrial Applications

Pneumatic cylinder position feedback is foundational to nearly every automated production line, and the SICK RZT7-03ZUS-KWB is routinely specified wherever T-slot cylinders drive clamping, indexing, ejection, or material-handling motion. In Oman’s growing industrial base — including packaging and bottling plants, food and beverage processing, and general machine-building workshops across Muscat — the SICK RZT7-03ZUS-KWB is used to confirm cylinder extend and retract positions feeding directly into PLC sequencing logic, helping operators catch a stalled or leaking cylinder before it causes downstream quality defects or unplanned downtime.

As the officially authorized partner for SICK, Seven Star LLC distributes the SICK RZT7-03ZUS-KWB to industrial buyers supporting the Sohar and Salalah economic zones, where petrochemical, port-logistics, and heavy manufacturing facilities depend on dependable pneumatic actuation for valve operation, conveyor diverters, and packaging-line automation. Its wide voltage tolerance and IP65/IP67 protection make it equally suitable for climate-controlled assembly halls and for outdoor or semi-exposed installations across the Sultanate of Oman and the broader GCC, where ambient dust, heat, and humidity would compromise less robust position-sensing technologies.
