Telco Sensors SPBS 2601 Industrial Proximity Sensor

The Telco Sensors SPBS 2601 is a background-suppression photoelectric proximity sensor in the SpacePak SP 2000 series, designed for non-contact object detection that ignores background surfaces in industrial automation. It operates on 10–30 VDC with an 880 nm infrared LED, offering a 1.5 m sensing range (adjustable) and selectable NPN/PNP transistor outputs with Normally Open or Normally Closed configurations to fit various control schemes. The 17 × 50 × 50 mm polycarbonate/ABS housing carries IP67 protection and a 5 m fixed cable, rated for -20°C to +55°C, with a range potentiometer and a light/dark switch for field tuning. Key performance specs include a 2 ms response time (ON) and 2 ms OFF, a maximum switching frequency of 250 Hz, a maximum output load of 200 mA at 30 VDC, and current consumption under 65 mA, along with reverse polarity and short-circuit protection. Common applications span packaging equipment, conveyor systems, warehouse logistics, food and beverage processing, assembly lines, and sorting systems, and the sensor is widely used by maintenance teams, OEM builders, and system integrators for repairs, retrofits, and control-system upgrades. Common replacements include SPBS 2600, SPBS 2602, and SPBS 2901.
