KHJ30 / 10 intrinsically safe emergency stop switch, two-way rope emergency stop switch, KHJ0.5 / 24 emergency stop switch, emergency stop sensors 1. Product Overview KHJ30 / 10 mine intrinsically safe emergency stop switch for coal mine methane other explosive gas environments, as shutdown protection along the belt conveyor can also be used for ground, mining, cement, coal preparation plant, power, ports and other belt conveyor or other equipments. 1.1 Standard: 1.2 Model and meaning: 1.3 Explosion-proof type: intrinsically safe. 1.4 Explosion-proof mark: "ExibI Mb", product compliance GB3836.4-2010 simple device. 1.5 Work: continuous work. 1.6 Dimensions: 165mm × 90mm × 160mm; weight 2kg ± 0.2kg. 1.7 Specifications: Action mode: Pull; Action Direction: Bidirectional; the output contacts: 1 normally open, 1 normally closed (changeover contact). 2. Working conditions 2.1 environment a) Ambient temperature: (0 ~ 40) ℃; b) Humidity: ≤98%; c) atmospheric pressure: (80 ~ 116) kPa; d) wind speed: ≤8m / s. 2.2 Transport and storage conditions a) Temperature: (- 40 ~ 60) ℃; b) Vibration: ≤50m / s2; c) Impact: ≤500m / s2. 3. Main features and technical parameters (1) Operation stroke: 10mm ± 2mm; (2) Operating force: 60N ± 10N; (3) the return force: 75N ± 15N; (4) normally closed contact closure resistance ≤0.1Ω; vibration, shock test after ≤0.2Ω; (5) Contact capacity: DC30V / 10mA (resistive load); (6) operational performance: locking switch by action force immediately after the operation and locked at the same time there are warning signs indicating, must After the manual reset to unlock. The operation principle of the two-way pull switch is operated, by the action force immediately after the operation and locked normally open contact closure, while there are warning signs indicating, in the immediate manual reset normally open contacts open and unlocked. 5. Installation using cable outer diameter of φ6 ~ φ10 (also with communication cables), not less than 2.5mm2. The emergency stop switch is fixed to the easy touch of place, when faced with an emergency, pull the switch, the contacts within the emergency stop switch operation output. Emergency stop switch for the two-way cable operation, by the action force immediately after the operation and locked inside the switch contact action, while there are warning signs indicating need to unlock after a manual reset.
