Telemecanique Current Switches

Overview

The TELEMECANIQUE ST08001 is an AC solid-state proximity sensor switch designed for conductivity-based presence sensing in industrial control applications. Operating at 120 VAC with a 3-amp current output, it uses solid-state electronics with no moving parts, eliminating the need for a relay in most circuits. The die-cast zinc enclosure carries a NEMA 1/4/13 rating, making it suitable for general-purpose, oil-tight, and dust-tight environments. A 3-foot SJTO cable provides direct wiring without additional connectors. Licensed electricians and controls technicians are the primary installers for this type of sensor. This sensor is suited for residential and light industrial automation panels, machine control circuits, and process equipment where precise conductive-material detection is required. The ST08001 performs well in applications demanding fast response without warm-up time, such as liquid-level detection or conductive-object presence verification. Its wide operating temperature range of -40 to 70 degrees C supports use in cold-storage or outdoor-rated enclosures where ambient conditions fluctuate significantly. Key Features Solid-state design with no moving parts for long service life and high reliability 3-amp high-current output eliminates external relay in most control circuits Fast response with 10-millisecond on delay and 100-millisecond off delay NEMA 1/4/13 rated die-cast zinc enclosure resists oil, dust, and general contaminants 3-foot SJTO cable connection…
