PANASONIC HL-G212B — Displacement Sensors
Panasonic HL-G212B: network-integrated laser displacement sensor, ±30 mm, resolution 4 μm, IP67.
Status: In production
Brand: Panasonic
Product: Network-integrated laser displacement sensor
Series: HL-G2
Measuring: ±30 mm
Resolution: 4 μm
Light: Red semiconductor laser, Class 2 (IEC / EN / JIS / GB / KS)
Protection: IP67 (IEC)
HL-G212B is a network-integrated laser displacement sensor from Panasonic’s HL-G2 series: the communication type (-S) carries Ethernet and RS-485 interfaces and an organic EL display on the sensor, while the analog output type (-A) delivers the measurement as an analog signal; it measures by diffuse reflection with a red semiconductor laser and CMOS image sensor. Measurement center distance 120 mm, measurement range ±30 mm. Resolution: 4 μm. Linearity (limited range): ±0.05 % F.S. (105 to 135 mm). Light source: Red semiconductor laser, Class 2 (IEC / EN / JIS / GB / KS), max. output 1 mW, 655 nm.
Sampling: 100 μs / 200 μs / 500 μs / 1 ms / 2 ms. Ethernet: 10BASE-T / 100BASE-TX (RJ45), auto negotiation; protocols: EtherNet/IP, Modbus TCP, SLMP. RS-485: 9,600/19,200/38,400/115,200/230,400 bps; Modbus RTU; up to 16 units. Supply: 24 V DC ±10 % (including ripple). Degree of protection: IP67 (IEC). Ambient temperature: −10 to +45 °C (no icing).
