Type JW Specifications
Description
NTC or PTC chip thermistor on a ceramic/metal shoe
assembly sealed in a polymer housing and provided
with flexible twin cable connections. The housing is
fitted with a spring metal clip for pipe attachment.
Options
• Other resistance - temperature characteristics
• Other wire lengths
• Special pipe sizes
General Data
• Minimum operating temperature: 32°F (0°C)
• Maximum temperature: 212°F (100°C) (sensor) 185°F
(85°C) (housing)
• Dissipation factor: ≥2mW/K (mounted on copper pipe
at 77°F (25°C))
• Isolation voltage: 500 VDC
• Clip force: <50N for mounting / de-mounting on pipe
5N will not cause rotation on pipe
• Shoe material: Plated brass
• Body material: Nylon
• Pack quantity & MOQ: 200 pcs
