Overview

The Carlo Gavazzi PMT20IM (SKU: PMT20IM) is a through-beam photoelectric emitter designed for precise long-range detection up to 20 meters in industrial environments. Using 880nm infrared modulated light, it delivers reliable operation even under high ambient light interference. The device supports a wide voltage range of 10.8–264VDC or 21.6–264VAC, making it compatible with most industrial power systems. It features a SPDT relay output with both normally open (NO) and normally closed (NC) contacts for flexible switching configurations. The PMT20IM is housed in a reinforced plastic/metal enclosure with IP67 rating, ensuring resistance to dust, moisture, and harsh conditions. Connection is via screw terminals, and the unit measures 25 x 65 x 81 mm. Designed for easy mounting in automation, material handling, conveyor systems, and industrial door applications, the emitter includes a mute input for verification of sensing function. The optical angle is ±2°, with a response time of ≤20ms (OFF-ON/ON-OFF) and a power-on delay of ≤300ms. Rated for mechanical life ≥40 x 10^6 operations and electrical life ≥5 x 10^5 operations at 220VAC/3A resistive load. Operating frequency is 20Hz, with sensitivity adjustable via a single-turn potentiometer.
