1. Mechanical and physical parameter requirements: Ensure the size, weight, sealing, strength, and weldability of the product's application device, lead pins, etc. This includes mechanical parameters such as contact pressure, contact clearance, contact tracking, restoring spring pressure, armature travel, and stop pin height.

2 Electrical parameter requirements: Ensure that the relay operates reliably and normally under regular operating conditions, accurately reflecting and transmitting speed signals. This includes electrical parameters such as winding resistance, contact electrical resistance, pull in current (voltage), rated operating current (voltage), release current (voltage), rated contact load, insulation resistance, and electrical strength.

3 time parameter requirements: In the control circuit, there are often requirements for the suction and release time of Xinchuangzhi relays, as well as time parameter requirements for armature conversion, contact jitter, pulse distortion, etc.

4 Environmental Habitual Requirements: Based on the application environment of the relay, in order to ensure reliable operation, environmental habitual items include: temperature (high and low temperature, temperature cycling, temperature shock, low temperature storage, etc.), moisture resistance (room temperature and high humidity, high temperature and high humidity), low pressure resistance, vibration stability and intensity, impact stability and intensity, constant acceleration. In special environments, there are also projects such as salt spray resistance, mold resistance, radiation resistance, transportation, and storage.

5 Life and power loss target requirements: Under regular experimental environmental conditions and contact loads, the number of errors in Xinchuangzhi relays should not exceed the requirements of product rules within the specified number of actions. The error referred to here refers to the bonding phenomenon when the contacts of the relay are disconnected during the action process, resulting in a voltage drop exceeding the regular level when the contacts are closed. Relays with reliability target requirements have power loss target level requirements.

6 Safety standard requirements: To avoid electric shock and fire, the product must comply with relevant national safety regulations, such as China Great Wall, Canada CSA, Germany VDE, TUV, etc.
