ZX Series (ZX-L-N) Smart Sensors (Laser Type) 5
■Amplifier Units
Item Model ZX-LDA11-N ZX-LDA41-N
Measurement period*1
*1. The response time for the first linear output or judgment output is calculated as follows (with fixed sensitivity): Measurement period × (Average
count setting + 1). The response time for the second and later outputs is the measurement period specified in the table.
150 μs
Possible average count settings 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1,024, 2,048, or 4,096
Temperature characteristic When connected to a Reflective Sensor Head: 0.01% FS/°C, When connected to a Through-beam Sensor
Head: 0.1% FS/°C
Linear output*2
*2. The output can be switched between a current output and voltage output using a switch on the bottom of the Amplifier Unit.
Current output: 4 to 20 mA/FS, Max. load resistance: 300 Ω
Voltage output: ±4 V (± 5 V, 1 to 5 V *3), Output impedance: 100 Ω
*3. Setting is possible via the monitor focus function.
