美国MERCOTAC水银接头，205型无刷滑环

Mercotac®无刷滑环

Mercotac®无刷滑环的工作原理优越。它们提供了极低电阻的电连接，因为导电路径是一种与触点分子结合的液态金属。Mercotac连接在滑环的使用寿命内保持不变。

电刷式滑环通常由一个旋转的金属环与石墨或金属电刷摩擦，传递电信号或电流组成。虽然电刷滑环在技术上操作简单，但摩擦界面可能导致各种问题。这些包括磨损、高电阻、氧化和电阻波动，这些都会导致电气噪声。

切换到Mercotac无刷滑环可以提供可靠，持久的连接，避免与刷式滑环相关的问题的卓越选择。看到不同之处

Accessories

Connector options are noted below. They are not included with a 205 Mercotac purchase. Order the desired connector(s) separately.

Description: Two Contact Receptacle
Item #: 591

• With one pre-attached 6” wire (18 AWG), center contact

• Customer may solder their own wire in the outer contact hole (18 AWG recommended)

• Suitable up to 4 Amps

Description:Two Contact Receptacle
Item #: 592

• With two pre-attached 6” wires (18 AWG)

• Suitable up to 4 Amps

Description: Two Contact Receptacle with Solder Holes
Item #: 594

• Two solder holes for 18 AWG wires

• Suitable up to 4 Amps

Description: Two Contact Cap
Item #: 595

• With two solder lugs for 18 AWG wires

• Suitable up to 4 Amps

A receptacle is used for mounting to the rotating device. The accessories are required for wire connections, since the Mercotac units cannot be soldered to directly. Order Separately.

Mounting

Model 205 is typically mounted by either the black body or the contact. Body mount typically uses a set screw or split clamp. Contact mount is held in the installed receptacle by a spring fit. It is best to mount the Mercotac so the body of the connector rotates. When used horizontally, mount the Mercotac so the body of the connector rotates.

Receptacle Mount

Bottom Mount with Conductive Shaft

Preferred mounting orientation.

Top Mount with Conductive Shaft

Use for top rotation.

Horizontal Mount with Electrically Insulated Shaft

The Mercotac body is electrically hot. An electrically insulated shaft can isolate it, if needed.

Thermal & Electrically Insulated Horizontal Mount

Use if electrical and thermal insulation is needed.

Protective Housing Mount with Conductive Shaft

Vibration Isolating Mount

Installation Notes:

• The up arrow should not point below horizontal.

• Do not solder to or bend terminals.

• Avoid lateral forces and mechanical loads (overly stiff or tight wires).

• Do not rigid mount both ends of the Mercotac.

• Limit the mounting eccentricity (runout / wobble) to .005" (.13mm).

• Provide overload protection within the circuit.

• Avoid vibration and bumping motions.

Connections

Model 205 Standard Wire Connections

The plastic cap with solder lugs attach to stationary wires

The metal receptacle press fits into rotating member of machine.

Model 205 plugs into the receptacle after the receptacle is press fit into the rotating member of the machine.

The cap plugs onto the stationary end of the 205 for the attachment of stationary wires.

Applications

Mercotac 205型无刷滑环满足各种应用的要求，如热电偶，应变片，涡流测试设备和风力涡轮机叶片传感器。凭借其紧凑的尺寸，可靠的信号连接，低扭矩和经济实惠的成本，它们是这些应用的绝佳选择。它提供了增强的性能和功能。值得注意的是，205型改进了它的前身，590型，最初是为莱斯利风琴扬声器设计的，用于连接电动风琴和旋转扬声器。经过多次尝试，这是唯一的滑环能够使这种高保真连接。

在下水道检查应用中，如左图所示，205型可用于电缆卷轴上，为灯供电或在电缆从卷轴上展开时将视频信号传输到电缆上。除了其他视频检测应用外，它们还用于茶包机和飞机机身的无损涡流裂纹检测。

这些滑环也发现相关的仪器，测试和测量设备，以及机器人。它们在仪器系统中提供稳定的信号传输，确保测试和测量设备中准确的信号传输，并使机器人运动平稳。Mercotac 205型无刷滑环是一种可靠且具有成本效益的解决方案，适用于各种应用，在不同行业中保持高效可靠的电气连接。
