DRT2-MD16TA (NPN)
DRT2-MD16TA-1 (PNP)
Note 1. V1 is not connected internally to V2, and G1 is not connected internally to
G2. Connect them carefully
2. When using inductive loads (such as solenoid valves), use a load with a
built-in diode to absorb reverse power or attach a diode externally.
3. Do not connect anything to the reserved terminals.
4. Wire colors have been changed according to revisions in the JIS standards
for photoelectric and proximity sensors. The colors in parentheses are the
wire colors prior to the revisions.
