* Care should be taken when utilizing these screw pitches to ensure that the physical load limits to the motor are not exceeded. Please consult the factory for advice in selecting the proper pitch for your application.

NOTE: All chopper drive curves were created with a 5 volt motor and a 40 volt power supply.

Ramping can increase the performance of a motor either by increasing the top speed or getting a heavier load accelerated up to speed faster. Also, deceleration can be used to stop the motor without overshoot.

With L/R drives peak force and speeds are reduced, using a unipolar drive will yield a further 30% force reduction.

Lubrication Options +

Haydon® Super Slick Greases

Haydon offers a wide selection of greases designed to meet any application requirements. Please contact Haydon Kerk Motion Solutions for assistance in selecting the most effective lubrication option.

	Grease Type	Chemical Compatibility	Temp. Range	Comments	Cost
HSS-03	Polyolester	Good	-54°C to +150°C	Moderate Load	$
HSS-17	Synthetic Hydrocarbon	Good	-20°C to +125°C	Standard	$
HSS-06	Perfluoropolyether	Best	-65°C to +250°C	Tough Environments	$$
HSS-16	Perfluoropolyether	Better	-80°C to +204°C	Vacuum compatible	$$$
HSS-20	Perfluoropolyether	Best	-65°C to +250°C	High Repeatability	$$$

HSS-03

is a light viscosity, polyolester based grease thickened with PTFE. It is an economical alternative to premium PFPE (perfluoropolyether) types where low temperature performance is a primary requirement as it provides low starting torque.

HSS-17

is a medium viscosity synthetic hydrocarbon grease thickened with lithium soap. It is fortified with EP (extreme pressure) modifiers to increase load carrying capabilities and TFE to increase lubricity and reduce friction. Rated temperature capacity is -20°C to +125°C. HSS-17 has the highest load characteristics.

HSS-06

is a TFE thickened heavy viscosity perfluoropolyether grease. It is designed to operate in chemically harsh environments and provides excellent operating properties for light to medium loads. Rated temperature capacity is -65°C to +250°C. Standard on Hybrid Actuators.

HSS-16

is a perfluoropolyether grease developed for use in vacuum environments good to 4x10–13 torr at 20°C. Rated temperature capacity is -80°C to +204°C.

HSS-20

is an ultrafiltered version of HSS-06, meaning that the grease it put through a ‘cleaning’ process to remove any particles greater than 35 microns in size. It is designed for use when accuracy and repeatability are of utmost concern.

Black Ice® and Kerkote® TFE Coatings

Black Ice and Kerkote TFE coatings are available in some of our actuator designs depending on the nut polymer used. Please consult the applications engineering team to discuss lead screw nut / TFE coating compatibility.

Encoders +

All Haydon hybrid linear actuators are available with a specifically designed encoder for applications that require feedback. The compact optical incremental encoder design is available with two channel quadrature TTL squarewave outputs. An optional index is also available as a 3rd channel. The size 6 encoder provides resolutions for applications that require 250 and 4000 counts per revolution. Encoders are available for the external linear configuration only. Captive and non-captive options are under development

Simplicity and low cost make the encoders ideal for both high and low volume motion control applications. The internal monolithic electronic module converts the real-time shaft angle, speed, and direction into TTL compatible outputs. The encoder module incorporates a lensed LED light source and monolithic photo-detector array with signal shaping electronics to produce the two channel bounceless TTL outputs.

Home Position Switch and Proximity Sensor +

Proximity Sensor

Haydon offers a miniature hall effect sensor capable of monitoring the end position of Can-Stack and Hybrid captive linear actuators.The sensor incorporates a hall effect device, which is activated by a rare earth magnet embedded in the end of the internal screw. The compact profile of the sensor allows for installation in limited space applications.The sensor has virtually unlimited cycle life. Special cabling and connectors can be provided. Haydon's end of stroke proximity sensor, and all Haydon Kerk Motion Solutions products are backed by a technical team which provides extensive customer support and applications assistance.
