D000: Standard hardened-steel tip

E010: M6 × 0.5 mounting thread

F0: Aluminum probe housing

G000: No integral cable (external coaxial cable to be specified by user)

H10: PTFE insulation spec for external cable

Range: 0–2.5 mm linear (ideal span 0.1–2.5 mm)

Sensitivity: 4 mV/µm (voltage mode) when used with standard conditioner

Frequency Response: DC to 20 kHz (–3 dB)

Output Impedance: ~500 Ω (voltage mode); ≤ 800 Ω load (current mode)

Supply: –20 V to –32 V DC from conditioner (≈ 13 mA typical draw)

Probe Body: 42 mm length × 12 mm Ø, aluminum housing

Tip: Hardened-steel, flush-mounted

Mounting Thread: M6 × 0.5

Cable: User-supplied PTFE-insulated coax per H10 spec

Operating Temp: –25 °C to +140 °C; Storage: –40 °C to +150 °C

Shock: 50 g, 2 ms (tip)

Vibration: ≤ 25 g peak, 5 Hz–5 kHz (body)

Pressure Rating: Up to 100 bar at probe face

Ingress: IP 65 at tip; IP 40 at cable junction (when mated)

ATEX Zone 1 (Ex ia IIC T6)

CSA Class I, Div 1, Groups A B C D

IEC 60529 / CE / CENELEC compliant

Linear, digital-grade displacement measurement over 0–2.5 mm with ≤ 1 % nonlinearity (with matched conditioner).

Lighter weight for applications where stainless-steel mass is undesired; withstands industrial shock and vibration.

No integral cable—enables flexible cable routing and custom lengths. Use PTFE-insulated, shielded coax meeting H10 spec for full bandwidth and environmental tolerance.

Wide Bandwidth

DC–20 kHz response captures both slow centerline shifts and high-frequency vibration without external filtering.

Operates to +140 °C, 100 bar pressure, and full IEC shock/vibration standards; IP 65 at the sensing tip.

ATEX Zone 1 and CSA Div 1 approvals allow direct use in classified locations when paired with approved conditioning equipment.

In long machinery rooms or retrofit scenarios, users specify cable lengths to suit panel layout. The aluminum-housed TQ402 mounts on bearing brackets, with field-installed coax to IQS conditioners in remote cabinets.

On small turbines with limited probe-pad mass budget, the lighter aluminum probe monitors radial shaft position and vibration; signals drive VM600 MPC4 protection logic to trip on excessive eccentricity.

For chemical pumps where stainless-steel housing might be overkill, the aluminum probe delivers accurate clearance measurements in splash zones, with PTFE-insulated cable routed back to safe-area IQS modules
