Spec Detail

Item Specifications
Product Number EX-29A
Part Number EX-29A
Regulatory compliance CE Marking (EMC Directive, RoHS Directive), UKCA Marking (EMC Regulations, RoHS Regulations)
Sensing range 30 to 200 mm 1.181 to 7.874 in
(Note) The sensing range and the sensing object of the retroreflective type sensor are specified for the RF-200 reflector. Further, the sensing range is the possible setting range for the reflector. The sensor can detect an object less than 30 mm 1.181 in away. However, if the reflector is set 100 mm 3.937 in or less away, the sensing object should be opaque.
Sensing object dia. 15 mm dia. 0.591 in or more opaque or translucent object
(Note) The sensing range and the sensing object of the retroreflective type sensor are specified for the RF-200 reflector. Further, the sensing range is the possible setting range for the reflector. The sensor can detect an object less than 30 mm 1.181 in away. However, if the reflector is set 100 mm 3.937 in or less away, the sensing object should be opaque.
(Note) Make sure to confirm detection with an actual sensor before use.
