Pepperl+Fuchs Inc., Twinsburg, OH, has expanded its ML4.2 Series of subminiature photoelectric sensors with new models offering faster response times, multibeam redundant detection, independent outputs, and zero deadband sensing. High-speed models offer 250 µs response time. Other models include dual-sensor redundant detection models, dual-sensor redundant detection and independent output models, precise sensing models, a retroreflective sensing model with no sensing deadband, and throughbeam sensors. All nonthroughbeam sensors feature integrated crosstalk immunity, 4-in-1 output, high immunity to ambient light, and diagnostic LEDs.
