5.Contact Analysis
6.Product Overview
The CNTD TZ-8166*is a compact plunger-type limit switch with a plastic rod coil-spring actuator, designed for precise position detection where space is tight and actuation force must be minimal.
Rated 250VAC / 6A with an SPDT contact and double-spring contact box, it sustains 500,000+ operations at 5 mm/s–0.5 m/s, up to 30 ops/min.
The standout feature is its ultra-light 1.5N operating force — the resin rod + stainless steel coil spring requires minimal push to trigger, making it ideal for detecting lightweight workpieces, thin materials, or fragile components without damage.
The IP65 sealed body runs from −20°C to +70°C (<95% RH). Certified CE / TÜV / CCC / ISO9001
