Other features include:

• Small size and high density (outside diameters for plugs (max) – 11mm: 4,6 and 8 positions; 13mm: 12,16 and 20 positions)
• Simple push-in/pull-out mating and un-mating
• Several mounting positions, styles and terminations
• Metal shells
• Termination style: crimping or soldering

Connector plugs for medical equipment

The TM-P series connector plug conforms to FCC standards. The six-conductor model conforms to RJ-11 standards, while the eight-conductor model conforms to RJ-45 and ISO8877 standards. A wide variety of cables are available, including flat and round copper foil stranded wires, non-shielded solid wires and thin stranded wires. Features include:

• Cable termination to pre-inserted contacts using a special manual tool
• Environment-resistive gold-plated terminals with a fire-retardant insulator (UL94V-0)
• A one-touch lock that offers excellent operability

Right-angle through-hole connectors

The TM-DS series of right-angle through-hole connectors conforms to FCC standards. The six-conductor opening model conforms to RJ-11 standards and the eight-conductor model conforms to RJ-45 and ISO8877 standards. Features include:

• Dip soldering horizontally to the PCB
• Gold-plated, environment-resistive terminals with a fire-retardant insulator (UL94V-0)
• Multiple port types have a six-conductor or eight-conductor opening in a wide variety of models, including space-saving types
• A space-saving model with a height of 11.7mm from the PCB surface, a width of 14mm, and a depth of 17mm is available

Straight through-hole connectors

The TM-DSA series of straight through-hole connectors conforms to FCC standards. The six-conductor opening model conforms to RJ-11 standards and the eight-conductor model conforms to RJ-45 and ISO8877 standards. Features include:

• Dip soldering vertically to the PCB
• The gold-plated terminals are environment-resistive with a fire-retardant insulator (UL94V-0)
• Multiple port types have a six-conductor opening in a wide variety of models with one to four ports
• Lightweight, compact design with PCB mounting space reduced

Wire-lead jack connectors

The TM-W series of wire-lead jack connectors conforms to FCC standards. The six-conductor opening model conforms to RJ-11 standards, while the eight-conductor model conforms to RJ-45 and ISO8877 standards. Features include:

• Jack with tin-coated lead wire connected
• The gold-plated terminals are environment-resistive with a fire-retardant insulator (UL94V-0)
• A variety of connectors can be connected to the opposite side of the lead wires
• Products are shipped with the lead wires connected

Electronic therapy, pulse-oximeters, slimming and muscle training, exercise counters and warm water cleaning units

Hirose started to develop and manufacture a variety of medical instruments in 1976. These products include electronic therapy devices for relieving pain and promoting blood flow, and measuring devices such as the pulse-oximeter, which is used to measure the oxygen concentration of blood.

In an effort to make medical technology available for practical use, Hirose has also focused attention in recent years on the development of health products for personal use and has already won a highly favourable market response with a variety of electronic products, including electronic devices for slimming and muscle training, exercise counters for lifestyle monitors and warm water cleaning units for portable toilets.
