• If a capacitor of 1 µF or more is connected between 0 V and

output or between +V and output, connect a 100 Ω resistor in

series as shown below.

Without the resistor, the short-

circuit protection is activated by

the charge or discharge current

of the capacitor, so that it

results in delaying the response

whenever the sensor switches.

The connected resistor solves

this problem.

Note:

GX-3S□, GX-4S□ and GX-5M□ do not incorporate a short-circuit

protection circuit at the output. Do not connect them directly to a

power supply or a capacitive load.
