CNTD CZ-7312 Precision Limit Switch

Product Overview

The CNTD CZ-7312 is a precision limit switch from the CZ-7 Series, featuring a panel-mounted vertical roller plunger actuator and snap-action 1NO/1NC contacts. Built for position detection, end-of-travel limiting and safety interlocking in industrial automation, its water-proof and oil-proof reinforced enclosure offers mechanical strength superior to conventional horizontal limit switches. Key ratings include a rated insulation voltage of 380 V, a conventional thermal current of 10 A, and certified safety ratings of 10 A/250 V (AC-15) and 0.3 A/220 V (DC-13). With IP64 protection on the operating surface and a -20 °C to +70 °C operating range, the CZ-7312 delivers dependable, long-life switching in dust-laden, oil-splashed and vibration-prone environments.

Key Selling Points

●Snap-action 1NO/1NC contacts — positive, repeatable switching with 25 mΩ max. contact resistance

●IP64 operating surface — water-proof, oil-proof reinforced enclosure for harsh industrial conditions

●Precise actuation — operating force 6 N, pretravel 2 mm, overtravel 6 mm, movement differential 0.8 mm

●Long electrical life — 500,000 operating cycles min. (250 V/6 A resistive load)

●High shock and vibration resistance — 1,000 m/s² (approx. 100 G); 10–55 Hz at 1.5 mm double amplitude

●Low-load capability — minimum applicable load DC 24 V 10 mA, ideal for PLC and low-power control circuits

●Robust insulation — rated impulse withstand voltage 4 kV; dielectric strength 1,500 VAC (terminals to ground)

●EU market compliance — CE and TÜV certified to EN 60947-5-1, plus CCC to GB/T 14048.5

Application Scenarios

The CZ-7312 is used wherever accurate position feedback and travel limitation are required:

●Machine tools and CNC equipment — end-of-travel and home-position detection on tables, spindles and tool changers

●Conveyors and material handling — presence detection, sorting control and end-stop protection

●Packaging and printing machinery — cycle counting, registration control and guard interlocking

●Elevators and hoisting equipment — car leveling, door-position and limit signaling

●Automated lines and robotics — position confirmation for gantries, grippers and safety gates

●Textile and woodworking machinery — durable switching under oil splash, dust and vibration
