800.727.5646 automatictiming.com Automatic Timing & Controls 7680 Series Self- Contained Sensors // 7680 Series 169 The 7680 Series was developed for its choice of AC/DC or DC power supply and small inexpensive package. Available in four operating modes. These sensors have a NEMA 4 rating and three output types: (Relay, FET or NPN), making this series ideal for many applications. • Compact Size • 10 to 30V DC or 10-135V AC/DC • NPN, Relay or Solid-State Output • Short and Long Range Diffuse • Polarized Retroreflective • NEMA 4 Housing • Output LED Mini Sel f -Cont a i n ed P ho to e l e c t r i c S e n s or \\\SPECIFICATIONS 7682A Short Range Diffused 7683A Retroreflective 7684A Long Range Diffused 7685A Retroreflective Polarized SENSING Maximum Distance 4" (10 cm) 12' (3.5 m)* 18" (0.5 m) 12' (3.5 m)* Minimum Target Size 0.2" (5 mm) 2.0" (5.1 cm)** 0.5" (1.25 cm) 2.0" (5.1 cm)** INPUT Voltage 10-30 VDC 10-30 VDC 10-135 VAC 10-30 VDC 10-30 VDC 10-135 VAC 10-30 VDC 10-30 VDC 10-135 VAC 10-30 VDC 10-30 VDC 10-135 VAC Current (nominal) 30 mA 45 mA 30 mA 45 mA 30 mA 45 mA 30 mA 45 mA OUTPUT Type NPN FET NPN FET NPN FET NPN FET Capacity 200 mA 100 mA 200 mA 100 mA 200 mA 100 mA 200 mA 100 mA Response Time <2 ms <3 ms <2 ms <3 ms <2 ms <3 ms <2 ms <3 ms Max.
