About the PW-61
PW-61 is a retro-reflective Main unit by Keyence. The PW-61 is a standard retro-reflective unit. The PW-66 has a detecting distance of zero point one to five (0.1 to 5)m or zero point three to sixteen point four (0.3 to 16.4) feet (with R-1). The PW-61 has an infrared LED light source. The PW-61 can detect opaque materials thirty by thirty (30 x 30)mm in one point one eight (1.18) inches minimum. The PW-61 has a response time of twenty (20)ms max. The PW-61 has a LIGHT-ON/DARK-ON (switch-selectable) operation mode. The PW-61 has a Red LED indicator lamp. The PW-61 has a control output of SPST-NO relay contact with a two-hundred and fifty (250) VAC three (3) A max., thirty(30) VDC three(3) A max. (resistive load). The PW-61 has a noise resistance of square-wave noise by a noise simulator: one (1) kV p-p, one (1) µs (across power terminals). The power voltage is 24 to 240 VAC ±10 %, 50/60 Hz, 12 to 240 VDC ±10 %. The PW-61 has a power consumption of three (3) VA max. The PW-61 has an enclosure rating of IP66. The PW-61 has an insulation resistance of twenty (20) MΩ min. (between each terminal and case, using insulation resistance metre of 500 VDC). The PW-61 has an incandescent lamp of five thousand (5,000) lux max., and sunlight of twenty thousand (20,000) lux max. The ambient temperature for the PW-61 is between negative ten to positive sixty degrees Celcius (-10 to + 60 °C) or fourteen to one-hundred and forty degrees Fahrenheit (14 to 140 °F). The PW-61 can NOT be exposed to any freezing.
