SPECIFICATIONS
■ Sensor head
*1 Reference distance
Small: 65 mm, medium: 60 mm, large: 50 mm
*2 Large spot: 15 ± 5 mm, small spot: 15 ± 3 mm
*3 The focus distance is about 10 mm, but stable detection can be achieved
with 15 mm.
■ Amplifier unit
*1 20 mA maximum when several units are connected.
*2 When several units are connected, the acceptable ambient temperature var-
ies depending on the conditions given below. To connect several units, be
sure to mount them to a DIN rail. Ensure that the output current is 20 mA max.
When 1 to 2 units are connected: -10 to +50 °C
When 3 units are connected: -10 to +45 °C
MOUNTING THE SENSOR HEAD
■ Extraneous light
A detection error may occur when the light from high-frequency lighting equipment
such as an inverter fluorescent lamp directly enters or reflected on the target into
the emitter. In such a case, apply a light shield plate or change the location of the
sensor.
■ Target movement and sensor orientation
To stabilize the sensor output at a border, mount the sensor as shown in the
following figure as much as possible.
■ When using the CZ-H32
When detecting a metal surface or glossy target
When a target has a metal or glossy surface, the calibration/differentiation
may fail. To detect such a target, tilt the sensor head by approximately 10 to
15 degrees.
■ When using the CZ-H35S/CZ-H37S/H72
When a target has a glossy surface (a birefringence target such as an ori-
ented film), the detection may fail depending on the mounting orientation. To
detect such a target, displace the sensor head by approximately 45 degrees.
