Festo SME-8M-DS-24V-K-0,3-M8D Proximity Sensor Reed 500mA 30V

Overview
The Festo SME-8M-DS-24V-K-0,3-M8D (part number 543861) is a robust magnetic reed proximity sensor from the SME-8M series, specifically designed for use in T‑slot cylinders and grippers. It provides precise, non-contact piston position detection for automation systems, with a service life of up to 14.91 million cycles, making it an ideal choice for high-frequency, long‑duration applications. This 3-wire sensor features a bipolar, Normally Open (NO) reed contact output, a wide operating voltage range of 5 to 30 V AC/DC, and a 0.3 m PUR cable terminated with a 3‑pin M8x1 plug, allowing for flexible mounting and integration. Designed for industrial automation, it excels in dynamic environments like energy chains and robotics, with an LED indicator for clear switching status and IP65/IP68 protection against dust, washdown, and temporary immersion.

Key Features

• Proximity Sensor with Reed Contact – Magnetic reed switching element for reliable, contact‑based position detection of metallic targets.

• 3‑Wire Normally Open (NO) Output – Bipolar/contacting output with a maximum switching current of 500 mA (80 mA when using mounting kits) for versatile control of small loads.

• Wide Operating Voltage Range – 5 to 30 V AC/DC, compatible with both AC and DC systems for flexible integration into existing controls.

• High Protection Class – IP65 and IP68 rated, dust‑tight and protected against water jets and temporary immersion, suitable for harsh environments.

• LED Switching Status Indicator – Yellow LED provides clear visual confirmation of the switching state, simplifying system diagnostics.

• Suitable for Dynamic Applications – Designed for use in energy chains and robotics with proven cable durability of over 5 million cycles at a 75 mm bend radius.

• Easy T‑Slot Mounting – Can be inserted into the slot from above or lengthwise and secured via screw clamp, providing a secure fit without protruding beyond the cylinder profile.

• Wide Temperature Range – Operates reliably from -40 °C to +70 °C, with a cable temperature range of -5 °C to +70 °C for moving applications, ensuring performance in extreme conditions.

• High Switching Frequency – Capable of up to 480 Hz for fast detection tasks.

• Oil Resistant – Designed for long-term stability in environments with oil mist, including those with food-grade lubricants.

• Original Brand New, Within Warranty Period – Genuine Festo product, brand new in sealed packaging, covered by manufacturer's warranty.

• 100% Satisfaction Guarantee – Your purchase is protected by our satisfaction guarantee; return or exchange if not completely satisfied.
