Electrical & Physical Specifications

Signal Protection and Enclosure Barrier Integration

The integrated output stage features reverse polarity and short-circuit protection against wiring errors in industrial control networks. The Varikont enclosure maintains high DIN-rail mounting stability when using mounting adapters, keeping surge voltage protection limits intact and maintaining low protocol conversion latencies when supplying discrete switching inputs to field signal isolators and intrinsic safety (Ex i) barriers.

Mechanical Mounting & Field Wiring

Sensing Head Positioning

Secure the Varikont rectangular housing to the machine frame using standard mounting screws. Ensure the target metallic object remains within the 0 to 12.15 mm safe operating distance window.

Cable Gland Terminal Connection

Unscrew the terminal box cover to expose the screw terminals. Thread the control cable through the PG/M20 cable gland and wire the supply (+UB, 0V) and dual PNP switching outputs (NO, NC).

High-Temperature Routing Precautions

Ensure field cables used in extended temperature zones carry an equivalent heat resistance rating to prevent insulation degradation near high-temperature machinery.

Frequently Asked Questions

• What does the "-T" suffix denote in the model number?

  The "-T" suffix indicates an extended temperature rating allowing operational functionality up to 100 deg C.

• How do the complementary PNP outputs (A2 function) operate?

  The sensor provides two concurrent PNP outputs: one normally open (NO) and one normally closed (NC) switching output.

• Can the orientation of the inductive sensing surface be adjusted?

  The Varikont sensor head can be unbolted and rotated into 5 distinct directions relative to the terminal base block.

• What supply voltage range powers the internal sensor electronics?

  The sensor operates across a standard filtered 10 to 30 VDC supply range with less than 10% ripple.

• What target material is calibrated for the 15 mm nominal sensing distance?

  The rated 15 mm sensing distance is based on a standard mild steel (FE 360) target measuring 45 mm x 45 mm x 1 mm.

• How should cable shielding be handled to avoid electrical noise interference?

  Connect the cable shield to the central cabinet earth ground bus bar to suppress high-frequency EMI in industrial environments.

• Does the output circuit incorporate overload protection?

  Both PNP transistor outputs feature built-in short-circuit and thermal overload protection to prevent driver burnout.

• What ingress protection level does the Varikont terminal housing achieve?

  When correctly assembled with a tightened cable gland and housing cover, the unit meets an IP68 ingress protection rating.
