Product Q&A

Q:Q1: What is the difference between TR236 and ZR236?

Q:Q2: What does 2NC mean?

A: 2NC means two Normally Closed contacts. Both circuits are closed in the resting state and open simultaneously when the switch is triggered. This dual-redundant design is critical for safety circuits.

Q:Q3: Which elevator brands is this compatible with?

A: Compatible with KONE, Mitsubishi, and other major elevator/escalator systems. It is commonly used as a tension pulley switch and buffer switch.

Q:Q4: What is the protection grade?

A: IP65 / IP67 with M20 cable entry and waterproof head - suitable for humid and dusty hoistway environments.

Q:Q5: What are the electrical specifications?

A: Rated insulation voltage Ui: AC500V. Rated current: 4A (AC-15) / 1A (DC-13). Rated impulse voltage Uimp: 6 kV.
