Banner Engineering SLM30P6Q-74974 Photoelectric Slot Sensor

SLM30P6Q-74974 is Banner Engineering's SLM Series Rugged Nickel-Plated Metal Fixed-Distance Slot Sensor, designed to detect metal workpieces within a 30 mm-wide slot. It uses an emitter/receiver pair with a maximum sensing range of 30 mm and a minimum object detection of 0.4 mm, making it suitable for precise presence sensing in tight slots. The unit is powered from 10-30 V DC and provides a PNP output on a 3-pin M8 integral quick-disconnect connection, with a zinc die-cast housing nickel-plated for durability in harsh manufacturing environments. It carries IP67 and NEMA 4X ratings, and includes LED indicators to show status. The sensor's response time is about 0.5 ms, with repeatability of 95 µs, and a power-up delay of 100 ms. Slot depth/array length is 60.8 mm, and the slot depth is listed as 62 mm (and 80 mm in some configurations). The SLM30P6Q also offers CAD data and documentation via Banner, and is part of a family intended for fixed-distance sensing in automation lines. Applications include detecting metal parts in guide slots on conveyors, ensuring part presence within a fixed-width slot, and aiding alignment in automated equipment where slot sensing provides reliable feedback.
