DIN HALF SIZE HOUR METER TH63·TH64 Hour Meters 57.5 2.264 24 .945 48 1.890 TH64 series (with reset button) mm inch TH63 series (without reset button) RoHS Directive compatibility information http://www.nais-e.com/ Features 1. Compact to save panel space The 24 × 48 mm hour meters are just half the DIN 48 × 48 standard size. They help save the panel space. UL File No.: E42876 CSA File No.: LR39291 2. Reset button The hour meters can be reset to zero (TH64 series). 3. Wide-ranging measurement display The measurement can be displayed from 0.1 hour up to 99999.9 hours (TH63 series). The dial size is the same as that of 48 × 48 DIN size hour meters (TH14 and TH24 series). 4. Easy to install The flat terminals (#187) are used for easier wiring. There is no need to undo the lock spring. 5. High-performance sync motor with 50/60 Hz selector The noise-resistant, accurately turning motor is employed to provide for longer period of measurement. The power frequency can be selected for 50 or 60 Hz. 6. Rotary indicator The rotary indicator makes one turn every 72 seconds for monitoring. 7. Compliant with UL, CSA and CE. Typical applications Management of small generators and food processing machines; hour counting for leased equipment; maintenance management of various equipment, etc. Specifications Rated operating voltage Allowable operating voltage range Rated frequency Counting range Minimum time display Rated power consumption Insulation resistance (Initial value) Breakdown voltage (Initial value) Max. temperature rise Vibration resistance Functional Shock resistance Functional Destructive Ambient temperature Ambient humidity Weight 12 V AC, 24 V AC, 48 V AC, 100 V AC, 110 V AC, 115 to 120 V AC, 200 V AC, 220 V AC, 240 V AC 85 to 115% of rated operating voltage 50/60 Hz (selectable by switch) 0 to 99999.9 hours (TH63 series) 0 to 9999.9 hours (TH64 series) 0.1 hours (6 min) Approx. 1.5 W Min. 100 MΩ, Between live and dead metal parts (At 500 V DC) 2,000 Vrms, Between live and dead metal parts 55°C 131°F 10 to 55 Hz: 1 cycle/min double amplitude of 0.5 mm (10 min on 3 axes) Min 98 m/s2 {10 G} (4 times on 3 axes) Min 980 m/s2 {100 G} (5 times on 3 axes) –10 to +50°C +14 to +122°F Max. 85% RH (non-condensing) Approx. 80 g 2.82 oz Product types Type Operating voltage Part number Operating voltage Part number Operating voltage Part number TH63 series (without reset button) 100V AC 200V AC 12V AC TH631 TH632 TH633 24V AC 48V AC 110V AC TH634 TH635 TH636 115 to 120V AC 220V AC 240V AC TH637 TH638 TH639 TH64 series (with reset button) 100V AC 200V AC 12V AC TH641 TH642 TH643 24V AC 48V AC 110V AC TH644 TH645 TH646 115 to 120V AC 220V AC 240V AC TH647 TH648 TH649 Notes) 1. Only the metallic-looking (silver) panel mounting type is available. 2. Standard products are UL-recognized as well as CSA-certified. There is no need to add “U” at the end of the part number. Just specify the standard part number when ordering. 174 Applic.
