IFM KI503A - Capacitive Sensor, M30 ATEX, 15 mm Adjustable

Q: What is the sensing range of the IFM KI503A and is it adjustable?

The KI503A has a sensing range of 15 mm, which is adjustable, with a real sensing range Sr of 15 mm +/- 10 %.

Q: What measuring principle and mounting does the KI503A use?

It is a capacitive sensor that is non-flush mountable.

Q: What ATEX rating does the KI503A carry?

It is ATEX marked II 3D Ex tc IIIC T90 C Dc, per approvals BVS 20 ATEX E 058 X and IECEx BVS 20.0061X.

Q: What output does the KI503A provide?

It has a PNP output with complementary function, rated 200 mA permanent current, with a maximum voltage drop of 2.5 V DC and a maximum leakage current of 0.1 mA.

Q: What is the switching frequency of the KI503A?

The switching frequency is 10 Hz.

Q: What is the operating voltage and current consumption of the KI503A?

It operates on 10 to 30 V DC and consumes less than 20 mA.

Q: What is the housing material, IP rating and temperature range of the KI503A?

The housing is PBT and PA with an M30 x 1.5 thread, rated IP 65 and IP 67, with an ambient temperature range of -20 to 60 C.

Q: How is the KI503A connected and protected?

It connects via terminals accepting 0.34 to 1.5 mm2 conductors through an M20 x 1.5 cable gland (cable sheath 5 to 9 mm dia), and is short-circuit proof with pulsed protection.

KI503A Applications

The IFM KI503A is a capacitive sensor certified for use in hazardous (dust Ex) areas. It is suited for level and presence detection of bulk solids and liquids in silos, hoppers and process vessels within ATEX Zone-22 environments. Its ATEX II 3D marking allows direct connection to the plant control without a switching amplifier, the sensing range is set easily via potentiometer, and the complementary NO/NC output plus clearly visible LED indication simplify integration and diagnostics in dusty industrial applications.
