SICK WT100-2N1439 | Mini Photoelectric Sensor, 1.2m Range, NPN
SICK WT100-2N1439 miniature energetic reflex sensor. 10-30V DC, NPN output, 0-1.2m range, IP67, M3 mounting. Ideal for object detection in tight spaces.
Product Overview
The SICK WT100-2N1439 is a compact miniature photoelectric sensor from the W100-2 series. This energetic reflex sensor (direct reflection type) features a very small housing (11x31x20 mm) with a surprisingly long detection range of up to 1.2 meters. It operates on a 10-30V DC supply with an NPN transistor output and includes a potentiometer for sensitivity adjustment and a switch for light/dark operation selection. Its tiny size and M3 threaded mounting make it ideal for space-constrained automation applications.
