SA1E Sensors SA1E Miniature Photoelectric Switches Key features: • Seven sensing methods: through-beam, polarized retroreflective, small beam reflective, diffuse, background suppression, conver- gent, and transparent. • 2m cable type and M8 connector. • NPN output, PNP output, light ON, dark ON can be selected. • Coaxial polarized retro-reflective type (SA1E-X) available for sens- ing transparent objects. • Background suppression (SA1E-B) type detects objects only, ignor- ing the background. • Red LED available for easy alignment in long distance applica- tions (SA1E-T, -P, -N, and -B) • Convergent reflective type (SA1E-G) is ideal for detecting objects at a short distance with a background. • Also available without sensitivity adjustment (SA1E-T, -P) • Air blower mounting block for installing an air blower to clean the lens surface. Ideal to maintain a clean lens surface and sensor performance. • UL Listed and CE marked R C US • IP67 Part Numbers Photoelectric Switches Part No. Cable Operation Sensing Method Sensing Range Connection Length Mode NPN Output PNP Output Light ON SA1E-TN1-2M SA1E-TP1-2M Cable 2m Dark ON SA1E-TN2-2M SA1E-TP2-2M 10m Light ON SA1E-TN1C SA1E-TP1C Connector – Dark ON SA1E-TN2C SA1E-TP2C Light ON SA1E-TN1-NA-2M SA1E-TP1-NA-2M Cable 2m Dark ON SA1E-TN2-NA-2M SA1E-TP2-NA-2M 15m Light ON SA1E-TN1C-NA SA1E-TP1C-NA Connector – Dark ON SA1E-TN2C-NA SA1E-TP2C-NA Light ON SA1E-TAN1-2M SA1E-TAP1-2M Cable 2m Dark ON SA1E-TAN2-2M SA1E-TAP2-2M 10m Light ON SA1E-TAN1C SA1E-TAP1C Connector – Dark ON SA1E-TAN2C SA1E-TAP2C Light ON/ Cable 2m SA1E-LTN3-2M SA1E-LTP3-2M Dark ON 30m Light ON/ Connector – SA1E-LTN3C SA1E-LTP3C Dark ON 1705151126 www.IDEC.com 210 SA1E Barriers Communication Sensors Power Supplies Automation Software PLCs OI Touchscreens Through-beam Class 1 Laser Red LED Infrared LED w/Sensitivity w/Sensitivity w/o Sensistivity w/Sensitivity Adjustment Adjustment Adjustment Adjustment OI Touchscreens PLCs Automation Software Power Supplies Sensors Communication Barriers SA1E Sensors Photoelectric Switches Part No. Cable Operation Sensing Method Sensing Range Connection Length Mode NPN Output PNP Output 2.5m (100 mm) Light ON SA1E-PN1-2M SA1E-PP1-2M When using IAC-R5/R8 Cable 2m 1.5m (100 mm) When using IAC-R6 Dark ON SA1E-PN2-2M SA1E-PP2-2M 1.3m (150 mm) When using IAC-RS2 Light ON SA1E-PN1C SA1E-PP1C 1.0m (150 mm) When using IAC-RS1 Connector – 0.8m (100 mm) Dark ON SA1E-PN2C SA1E-PP2C When using IAC-R5/R8 3.0m (100 mm) Light ON SA1E-PN1-NA-2M SA1E-PP1-NA-2M When using IAC-R5/R8 (Note) Cable 2m 2.0m (100 mm) When using IAC-R6 Note: Maintain at least the distance Dark ON SA1E-PN2-NA-2M SA1E-PP2-NA-2M shown in the ( ) between the SA1E 1.4m (150 mm) photoelectric switch and reflector.
