More Info

The HD Series HMDs are radiation detection photo sensors with separate amplifiers that have achieved compact sizes and low cost.

HD301N and HD601N are intended for sites where temperature in the vicinity of the receiver is up to 50 or 70 C and available in models for low temperature and medium/high temperature. Applications include detection of presence or passage of heated steel material, glass, etc.

HD400 and 502F are fiber optic cable sensors with ultra-small heads.
Applications include detection of heated steel material, glass, etc.

  • Low cost
    The HD Series offers the lowest cost of all HMDs. Amplifiers are separately installed and no water-cooling is involved.
  • Airless hood provided
    The HD Series sensors come with Airless hood for prevention of soiling of lens.
  • Fiber type
    HD 400 may be used in combination with heat resistant generic fiber optic cables, which improves the resistance to heat and electric safety of the sensing head. Attaching a lens unit at the end extends the detecting distance.
    HD502F is the most competitive model of HMD. The fiber optic cable covered with ø1.1mm stainless tube allows focused detection of heated condition of electronic components or mechanical parts.

Compact multifunctional amplifier (HDA300A)

  • 3 point level indicator
    The received light intensity level is shown by flashing 3 indictors for easy checking of stability.
  • Sensitivity adjustment volume
  • Relay output and voltage output available
